Yintoni i-C # kwaye Ikhanya phi

I-C# (ebizwa ngokuba yi-C-sharp) lulwimi lwenkqubo lwangoku, olujoliswe kwinto yonke oludalwe nguMicrosoft njengenxalenye yeqonga le-NET, eliyilelwe ukuba libe namandla, uchwethezo olukhuselekileyo, kwaye kwangaxeshanye kube lula ukulichola ukuba uyazazi iilwimi ezifana neJava, C++ okanye nezinye ii-syntaxes ezifana ne-C. Ekuqaleni yayikhokelwa nguAnders Hejlsberg, injineli efanayo emva kweelwimi ezifana neTurbo Pascal kunye neDelphi.

Ngokwezinto eziphathekayo, i-C # isetyenziswa ngokubanzi ukwakha uluhlu olubanzi lwezicelo, esinye sezizathu ezigcina ubukho obuqinileyo kwimarike yomsebenzi. Iimeko zokusetyenziswa eziqhelekileyo ziquka:

• Usetyenziso lwewebhu nge ASP.NET kunye ne ASP.NET Core.
• Isoftware yedesktop usebenzisa iiFom zeWindows okanye iWPF.
• Ukuphuhliswa komdlalo ngoManyano, apho iC# ilulwimi oluphambili loshicilelo (umzekelo, hlela umbhalo we-TextMeshPro).
• Ilifu, ii-APIs, kunye neenkonzo ze-AI phezulu kweAzure okanye ezinye iziseko.

Ulwimi luqokelelwe kwaye lusebenza kwi-.NET runtime, elawula imemori kwaye inyanzelise ukuchwetheza okuqinileyo, kukunika ulungelelwaniso oluhle phakathi kokusebenza, ukhuseleko, kunye nemveliso yomphuhlisi. Eso sesinye sezizathu zokuba iinkampani ezinje ngeMicrosoft, iStack Overflow kunye namaqela amaninzi oshishino athembe iC # kwiinkqubo ezibalulekileyo.

Ukufunda i-C# Ngokusebenzisa iziFundo eziSebenzayo, imizekelo, kunye neeQuiz

Izifundo zangoku ze-C # zihlala zihamba ngaphaya kokubhaliweyo okumileyo kwaye zikunika umhleli webhrawuza apho unokuqhuba kwaye uguqule ikhowudi ngoko nangoko, eluncedo kakhulu xa usaqala kwaye ungafuni kujongana nofakelo. Ezi ndawo zisebenzisanayo zikuvumela ukuba wenze i-snippet, ucofe iqhosha elithi "Baleka" okanye "Hlela & Run", kwaye ngoko nangoko ubone imveliso.

Iikhosi ezininzi ezikumgangatho ophezulu we-C # zakha isahluko ngasinye malunga nemizekelo emifutshane, egxininisekileyo ebonisa ingcamango enye ngexesha, ukusuka kwi-syntax esisiseko ukuya kwizihloko eziphambili ezifana nokutshatisa ipateni okanye ii-tuples. Ungahlela ezi sampuli ngokuthe ngqo, ulinge ngamaxabiso ahlukeneyo, kwaye ufunde ngokuqaphela kunokuba ufunde ithiyori kuphela.

Ukubethelela oko usandula ukukufunda, uninzi lwezifundo ziphelisa izahluko zazo ngokuzilolonga ngezandla kwaye ngamanye amaxesha iikhwizi ukujonga ukuqonda kwakho. Ukuzivocavoca kukucela umngeni ukuba ubhale okanye uguqule ikhowudi ngokwakho, ngelixa iikhwizi zikunika ingxelo ekhawulezayo malunga nokuba zeziphi izimvo ozifunxe ngokupheleleyo kwaye zeziphi onokufuna ukuzindwendwela kwakhona.

Amanye amaqonga akwabonelela ngengqokelela epheleleyo ye-C # yomzekelo onokuthi ukhangele ngokuzimeleyo kulandelelwano lwekhosi engqongqo, eluncedo xa ufuna ukujonga into ethile efana nokuphatha iifayile, iilophu, okanye iiklasi kwaye ubone i-snippet esebenza ngokupheleleyo. Le ndlela "yokufunda ngemizekelo" yenza kube lula ukudibanisa iinkcazo ezingabonakaliyo kunye nekhowudi yokwenyani.

Indlela yokufunda eLuhlobo lwabaQalayo yeC#

Ukuba umtsha kwi-C # (okanye nakwinkqubo ngokubanzi), inyathelo-ne-step indlela eyakha ngokuthe ngcembe kwizifundo zangaphambili iya kukugcina uziva ulahlekile okanye utsibe phambili kakhulu. Ezona zifundo zibalaseleyo zithatha amava e-zero ekuqaleni kwaye zinyuse ubunzima ngokucotha njengoko uziqhelanisa.

Izixhobo ezininzi zicebisa ukuba uqale ngothotho lwevidiyo eyintshayelelo okanye uluhlu lokudlalayo lwabaqalayo ukuze uzive ngolwimi ngaphambi kokuba ungene kwizifundo ezisebenzisanayo ngokupheleleyo. Umzekelo, unokuqala ukubukela iividiyo ezimfutshane ezichaza ukuba yintoni i-C #, injani .NET isebenza njani, kwaye injani inkqubo elula ekhangeleka ngayo, ngoko ngoko nangoko womeleze oko ngokubhala ikhowudi ngokwakho kumhleli we-intanethi.

Izifundo zokuqala zihlala zikuhamba ngezinto ezingundoqo zesintaksi, njengokuchaza indawo yokungena yenkqubo, indlela yokubhengeza izinto eziguquguqukayo, kunye nendlela yokubhala isiphumo kwikhonsoli. Ukusuka apho, isahluko esitsha ngasinye sakhela kwinto osele uyibonile, ke ukuzenza ngolungelelwano kubonelela ngamava agudileyo-nangona ukuba sele ukhowudi ngolunye ulwimi, unokutsiba okanye utsibe iziseko ezisisiseko.

Omnye umba omnandi womxholo wokufunda weC # kukuba uhlala uphatheka kwiindawo ezahlukeneyo: ungaqala ngomhleli osekwe kwisikhangeli, emva koko utshintshele kwiKhowudi yeVisual Studio okanye i-IDE epheleleyo kamva, kunye nemizekelo yekhowudi efanayo kunye neengqikelelo ezisisiseko zisasebenza. Ulwimi luhlala lufana; izixhobo zokutshintsha kuphela.

Inyathelo lokuqala lakudala: "Molo, Hlabathi!" kwi C#

Mhle kakhulu yonke i-C # yokufundisa iqala ngokuncinci Molo Lizwe! inkqubo kwi C# ngoko unokubona ngokupheleleyo, umzekelo osebenzayo ukusuka phezulu ukuya ezantsi. Isiqwengana esiqhelekileyo sazisa iziqwenga ezingundoqo zesintaksi kwishothi enye.

Inkqubo esisiseko yeconsole kwi C# ichaza iklasi, ibhengeza indlela esisigxina engashukumiyo njengendawo yokungena, kwaye isebenzisa indlela yeConsole.WriteLine ukuprinta okubhaliweyo. Unokubona into efana nale yolwakhiwo lwengqiqo:

using System;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Hello, World!");
    }
}

Kolu lwakhiwo, ukusetyenziswa kweNkqubo; Umyalelo wenza iSixokelelwano samagama sifumaneke, kulapho ihlala khona iConsole, ngelixa iklasi yeNkqubo isebenza ngokulula njengesikhongozeli seNdlela ePhambili ethi ixesha lokubaleka lifowuna xa usetyenziso lwakho luqala. Umnxeba oya kwiConsole.WriteLine ubhala umyalezo olandelwa ngumgca omtsha kwifestile yeconsole.

Izifundo ezisebenzisanayo zihlala zikuvumela ukuba uqhube olu hlobo lomzekelo ngqo kwibhrawuza ngokucofa iqhosha, kwaye ukusuka apho uyakhuthazwa ukuba utshintshe okubhaliweyo, wongeze imigca eyongezelelekileyo, okanye ulinge nezinye iingxelo. Lolophu yengxelo yangoko ikunceda ukuba ufunde ngokukhawuleza kunokufunda nje ikhowudi.

Ukusebenza ngamaNani, iiNdidi zeDatha, kunye neeNguqulelo

Wakuba uprinte umtya kwikhusi, inyathelo elikhulu elilandelayo kukuqonda ukuba iC# iphatha njani iindidi ezahlukeneyo zedatha ezinje ngenani elipheleleyo, amanani-amanqaku adadayo, imitya, kunye ne booleans. Apha kulapho ufunda khona malunga neentlobo kunye nezinto eziguquguqukayo, kubandakanya i-enums - bona ukuba wenze njani ukubala inani lamaxabiso e-enum.

C# ichwethezwe ngamandla, oku kuthetha ukuba zonke iintlobo zinodidi oluthile olufana ne-int, kabini, umtya, okanye i-bool, kwaye umqokeleli ujonga ukuba usebenzisa ezo ntlobo ngokungaguqukiyo. Izifundiso zihlala zibonisa imizekelo efana nokuseta inani elipheleleyo lobudala, umtya wegama lomsebenzisi, okanye kabini ngexabiso, emva koko uziprinte ngeConsole.WriteLine.

Isiqwengana esiqhelekileyo sabasaqalayo sinokubhengeza i-int yobudala kunye nomtya wegama lomntu, emva koko uwadibanise kumyalezo. Emva koko ungawaguqula amaxabiso ukuze ubone ukuba isiphumo sitshintsha njani, sikunceda ukuba ubambe indima nganye edlalwayo kwinkqubo yakho.

Izifundo zabaqalayo ezihambele phambili zihlala zingena kwindlela iikhompyutha ezigcina ngayo amaxabiso amanani, ukuquka inani elipheleleyo xa lithelekiswa namanqaku adadayo, i-arithmetic esisiseko, ukuziphatha okurhangqwa, kunye nendlela iindidi zamanani ezahlukeneyo (ezifana ne-int, inde, ukudada, kabini, idesimali) zisebenza ngeenjongo ezahlukeneyo. Ukuqonda oku kunceda ukunqanda iimpazamo ezifihlakeleyo ekubaleni kamva.

IiTuples, Iintlobo zesiNtu, kunye nokwakha ezakho iZakhiwo

Emva kokuba ukhululekile ngeentlobo zedatha yakudala, i-C # tutorials idla ngokuzisa iindlela ezicwangcisiweyo zokumela idatha, ezinje ngee-tuples, iirekhodi, iistructs, kunye neeklasi. Olu lwakhiwo lukuvumela ukuba uqokelele amaxabiso amaninzi ngokwengqiqo abe kunye.

Iikopi kwi C# zikuvumela ukuba uqokelele uluhlu lwamaxabiso kwinto enye ngaphandle kokwenza uhlobo olunikwe igama, oluluncedo kakhulu ekubuyiseleni amaxabiso amaninzi kwindlela okanye ukudlula iiseti zedatha eziqokelelweyo. Ngokomzekelo, umsebenzi unokubuyisela zombini iflegi yempumelelo kunye nomyalezo njenge-tuple enye.

Iirekhodi, into entsha ye-C #, zihlala ziboniswa kwii-tutorials zanamhlanje njengendlela emfutshane yokuchaza iindidi zedatha ezingenakuguquleka kunye nokulingana kwexabiso elakhelwe ngaphakathi. Zintle xa ulinganisa idatha ye-APIs okanye izinto ze-domain apho ukhathalele khona amaxabiso ngaphezu kwesazisi.

Ulwakhiwo kunye neeklasi zingumqolo wenkqubo ejolise kwizinto kwi-C #: i-structs ichaza iindidi zexabiso eziqhele ukuba zincinci kwaye zikhutshelwe ngexabiso, ngelixa iiklasi zichaza iindidi zereferensi ezihlala kwimfumba kunye nenkxaso yelifa. Izifundo zihlala zibonisa imizekelo elula eqaqambisayo xa unokukhetha enye phezu komnye ngokusekwe ekusebenzeni okanye kwisemantics.

Ukuqukuqela okuLawulayo: Amasebe kunye neeLoops

Ukuhamba kokulawula yinto evumela inkqubo yakho ukuba yenze izigqibo kwaye iphinde imisebenzi, kwaye i-C # tutorials inikezela amacandelo apheleleyo kwi-branching (ukuba, ngenye indlela, tshintsha) kunye nolwakhiwo lwe-loop (for, ngelixa, ukwenza-ngelixa, ngaphambili). Ukuqonda ezi patheni kubalulekile kuba phantse yonke ingqiqo yehlabathi lokwenyani ixhomekeke kuzo.

Umzekelo wangaphambili, oqhelekileyo usebenzisa inkcazo ukuba-enye ukujonga into efana neminyaka yomntu kwaye emva koko uprinte umyalezo njengokuthi uvumelekile na ukuvota. Ufunda igalelo lomsebenzisi, uliguqule libe linani elipheleleyo, kwaye emva koko uvavanye imeko ukwenza isigqibo ngomyalezo omawuboniswe.

Iiluphu ziza ngokulandelayo, zihlala ziluhlobo olulula lweluphu eprinta uthotho lwamanani okanye imiyalezo, ekuvumela ukuba ubone ngokubonakalayo ukuba iiteration isebenza njani. Ngokutshintsha ixabiso lokuqala, ixabiso lesiphelo, kunye nokwandiswa, unokuzama ukuba mangaphi amaxesha asebenzayo iluphu kwaye iprinta ntoni.

Ezinye izifundo zandisa oku ngelixa kwaye usenza-ngelixa iilophu, zikubonisa indlela yokuphinda ibhloko yekhowudi ukuba imeko ihlala iyinyani, eluncedo kakhulu ekuqinisekiseni igalelo okanye kwimisebenzi eqhuba ixesha elide. I-loop yangaphambili yaziswa kamva njengendlela efanelekileyo yokuphindaphinda ingqokelela efana noluhlu kunye noluhlu.

Iingqokelela: Ukusebenza ngoLuhlu kwi-C#

Iinkqubo zokwenyani azifane zisebenze ngoguqulo olunye okanye ezimbini; endaweni yoko, bakhohlisa ingqokelela yedatha, kwaye yiloo nto i-C # tutorials zinika ingqalelo ekhethekileyo kuhlobo lokuqokelela uLuhlu. Uluhlu lubonelela ngendlela eguquguqukayo yokugcina ulandelelwano lwezinto kwinkumbulo.

Uluhlu oluqhelekileyo I-tutorial ihamba nawe ngokwenza uluhlu, ukongeza nokususa izinto, ukukhangela izinto, kunye nokuhlela uluhlu ngeendlela ezahlukeneyo. Ungabona umzekelo ogcina uluhlu lwamagama amele amagama, emva koko usebenzise iindlela ezinje ngo Faka, Susa, Iqulethe, okanye Hlela.

Ngaphaya kwemisebenzi esisiseko, ezinye izifundo ziqaqambisa inyani yokuba unokuba noluhlu lwezinto ezintsonkothileyo, hayi nje amaxabiso akudala, avula umnyango wokwakha imodeli yedatha eyinyani. Umzekelo, Uluhlu lwezinto zeMoto okanye izinto zeMveliso zinokubonisa idatha yeshishini kwimemori.

Ukuphonononga uluhlu lwe-API kukunika ukuziva malunga nendlela ilayibrari yengqokelela ye-NET eyenzelwe ngayo, kwaye olu lwazi lugqithisela kwezinye iindidi zokuqokelela njengezichazi-magama, imigca, kunye nezitaki xa udibana nazo kamva.

Ipateni yokuTyatshaniswa kweKhowudi eQinisayo ngakumbi

I-C# yale mihla ibandakanya iipatheni ezomeleleyo ezihambelanayo ezikuvumela ukuba ubonise uqikelelo olunemiqathango oluntsonkothileyo ngendlela efundekayo, echazayo. Uninzi lwezifundo ezihlaziyiweyo ngoku zinikezela amacandelo apheleleyo ekuchazeni nasekuboniseni obu buchule.

Ukuthelekisa ipateni kukuvumela uthelekise ixabiso ngokuchasene nomzekelo onokubandakanya uhlobo lwayo, iipropati, okanye nolwakhiwo loluhlu, kwaye ngokusekelwe ekubeni ipateni iyahambelana, ikhowudi yakho ithatha amasebe ahlukeneyo. Oku kukholisa ukuvela kwiintetho zokutshintsha okanye kwiingxelo zokutshintsha ezongeziweyo.

Unokudibanisa iipateni ezininzi usebenzisa iziqhagamshelo ezinengqiqo ezifana kunye, okanye, kwaye hayi, nto leyo ekhokelela kwikhowudi emfutshane yeemeko ezinokuthi zifune ukuba iinkcazo ezininzi zifakwe kwindlwane. Umzekelo, unokutshatisa kuzo zombini udidi lwento kunye nexabiso lenye yeepropathi zayo kulwakhiwo olunye.

Ngokuziqhelanisa nongqamaniso lwepateni, ufunda ukubhala ikhowudi ye-C # egcinekayo ngakumbi kwaye kulula ukuqiqa ngayo, ngakumbi xa ujongana nedatha engafaniyo okanye imithi yezigqibo ezinzima.

Imisebenzi, Iindlela, kunye neNgqiqo eSebenziswa kwakhona

Olunye ugxininiso oluphindaphindiweyo kwi-C # tutorials yimisebenzi (iindlela kwi-C # isigama), kuba ziyibhloko yokwakha yengqiqo enokuphinda isetyenziswe kunye nesakhiwo esicocekileyo. Endaweni yokuphinda ikhowudi enye kwiindawo ezininzi, uyifakela ngendlela kwaye uyibize kwiMain okanye kwezinye iindawo zenkqubo yakho.

Umzekelo wentshayelelo olula ukholisa ukuchaza indlela emileyo ethatha iparamitha enye okanye ngaphezulu, yenza isenzo-njengokushicilela isibuliso-kwaye uyibize kaninzi ngeengxoxo ezahlukeneyo. Oku kubonisa indlela ogqithisa ngayo ulwazi kwaye ufumane iziphumo kwakhona.

Ukusuka apho, iikhosi zihlala zingena kumaxabiso embuyekezo, indlela yokulayisha ngaphezulu, kunye nendlela iindlela ezingena ngayo kwiiklasi kunye nezinto. Ukuqonda iiparamitha kunye neentlobo zembuyekezo kubalulekile ngaphambi kokuba uqhubele phambili kubuchule obujolise kwinto okanye iipatheni ezingaphezulu zokusebenza.

Ngokuziqhelanisa nokubhala iindlela eziluncedo ezincinci, uziqeqeshela ukubona amathuba okuhlaziya kunye nokuthatha okucacileyo, okuhlawula kakhulu kwiiprojekthi ezinkulu ze-C # kamva.

Inkqubo eJoliswe kwiNjongo: Iiklasi kunye neZinto kwi-C#

I-C # ngokusisiseko ijolise kwinto, ke nasiphi na isifundo esinzulu sichitha ixesha elininzi kwiiklasi, izinto, amasimi, iipropathi kunye neendlela. Apha kulapho usuka khona kwimibhalo emincinci, enye ukuya kwiinkqubo ezicwangcisiweyo ezinemodeli ecacileyo yeengqikelelo zehlabathi lokwenyani.

Umzekelo othe ngqo wabaqalayo unokuchaza iklasi yeMoto enebala likawonke-wonke okanye ipropathi yophawu kunye nendlela eprinta igama lebrendi, emva koko udale umzekelo walo didi kwiMain, seta ixabiso leBrand, kwaye ubize indlela. Oku kubonisa ngokucacileyo ukuba kuthetha ukuthini ukumisela into kunye nokusebenzisana namalungu ayo.

Ukusuka apho, izifundo ziye zanda ukuya kwizilungisi zofikelelo, abakhi, i-encapsulation, ilifa, kunye ne-polymorphism, nangona ezo zihloko eziphambili zihlala zingena kwizahluko zamva nje ukuba ukhululekile ngeenkcazo zeklasi ezisisiseko. Ingcinga engundoqo kwangethuba kukuba unokumisela umzekelo wamaziko anedatha yomibini (imimandla/iipropathi) kunye nokuziphatha (iindlela).

Ukuqonda udweliso lwenkqubo olujolise kwizinto kwi-C # kukulungiselela yonke into ukusuka kwi-desktop ye-GUI ye-apps ukuya kwi-ASP.NET izicelo zewebhu kunye nemibhalo yomdlalo we-Unity, kuba zonke zithembele kakhulu kwezi ngcamango ezifanayo.

Ukufunda nokubhala iiFayile kwi-C#

Ngokukhawuleza ukuba ufuna ukuqhubeka nedatha okanye usebenze ngoqwalaselo, ufuna ukuphathwa kwefayile, kunye ne-C # tutorials zihlala zibandakanya ubuncinane umzekelo osisiseko usebenzisa i-System.IO namespace. Oku kukunika incasa yokunxibelelana nenkqubo yokusebenza ngaphaya kweconsole.

Umboniso weklasikhi olungele abasaqalayo ubhala umtya olula kwifayile yokubhaliweyo (bona indlela yokwenza yenza ifayile yokubhaliweyo kwi C#) kwaye emva koko ifunde umva, ishicilela imixholo kwi console. Ixhomekeke kwiindlela eziluncedo zomncedisi ezifana neFayile.BhalaAllText kunye neFayile.ReadAllText ukuze ungalawuli imijelo ngokwenza kutyhileko lwakho lokuqala.

Ukuzama imizekelo enjalo kumatshini wakho wobulali kukunceda uqonde ukuba iinkqubo zakho ze-C # zinokudala, zifunde, kwaye zihlaziye iifayile kulawulo lwangoku okanye kwiindlela ezithile. Ukwafunda ukuba le misebenzi iphantsi kweemvume kunye nemithetho yefayile yeqonga lakho.

Kamva, izifundo eziqhubela phambili zinokuzisa iifayile zokubini, abalawuli, imilambo, kunye ne-async ye-I/O, kodwa umboniso wokuqala wokufunda nokubhala ifayile yombhalo olula udla ngokwanela ukuvelisa izimvo zezinto ezincinci okanye izixhobo onokuzakha.

Kutheni i-C # ilulwimi olukhulu lokufunda

Omnye weyona mibuzo iqhele ukubuzwa ngabaqalayo kukuba "Kutheni kufuneka ndikhethe i-C # kwezinye iilwimi?" kunye nezifundo ezibeka kakuhle ngokwesiqhelo ziphendula oku ngokujolisa kwizinto ezininzi, ukufikeleleka, kunye namandla. I-C# ibetha indawo emnandi phakathi kweempawu ezomeleleyo kunye ne-syntax elungele abaqalayo.

Ngenxa yokuba i-C # isetyenziswa kakhulu kwii-backends zewebhu (nge-ASP.NET), i-desktop apps, imidlalo (Ubunye), kunye neenkqubo ezininzi zezoshishino, ukufunda kuvula iingcango kumashishini amaninzi. Awutshixelwanga kwi-niche enye; ungajikeleza phakathi kwe-APIs yokwakha, izixhobo, kunye namava asebenzisanayo.

I-syntax iya kuziva iqhelekile ukuba ukhe wayibona iJava okanye i-C ++, kwaye nokuba umtsha kraca kwiprogramu, ulwakhiwo lunengqiqo ngokwaneleyo ukuba unokwenza inkqubela ngokuthe chu. Ixesha le-.NET lokusebenza kunye namathala eencwadi abonelela nge-ecosystem enkulu yokusebenza esele ilungile kuyo yonke into ukusuka kuthungelwano ukuya ekufundeni koomatshini.

Ngaphezulu koko, i-C# ithathwa njengohlobo olukhuselekileyo, oluneempawu ezifana nejenerics, iintlobo zereferensi ezingasebenziyo (kwiinguqulelo zamva nje), kunye nemodeli yememori elawulwayo, ikwenza kube lula ukunqanda iindidi zeempazamo eziqhelekileyo kwiilwimi ezikumgangatho ophantsi.

IsiFundo esicwangcisiweyo: Imithambo, iiQuiz, kunye namaThala eencwadi angumzekelo

Umgangatho ophezulu wezifundo ze-C # zigqamile kuba azibonisi nje ulwazi; zikunceda ujonge ukuqonda kwakho ngemithambo kunye neekhwizi. Emva kwengcamango nganye, uhlala unikwa umbuzo okanye umsebenzi wokubhala ikhowudi ukuqinisekisa oko ukufundileyo.

Ukuzivocavoca kunokuvela kwiinguqu ezincinci kwimizekelo ekhoyo-njengokutshintsha amaxabiso aguquguqukayo okanye iimeko-ukubhala imisebenzi emfutshane okanye iiklasi ukusuka ekuqaleni. Olu hlobo lokuziqhelanisa lunyanzela ingqondo yakho ukuba ikhumbule kwaye isebenzise ulwazi kunokuba uyiqonde esikrinini.

Iikhwizi, ngokuqhelekileyo kwifomathi yokhetho oluninzi okanye yeempendulo ezimfutshane, ikunika umqondiso ngoko nangoko malunga nenqanaba lakho langoku: ukuba usoloko uyiphosa imibuzo ngesihloko, luphawu lokuphinda ulifunde elo candelo okanye wenze okungakumbi. Olu vavanyo lukugcina unyanisekile malunga nenkqubela phambili yakho.

Ukongeza kulandelelwano olucwangcisiweyo, amaqonga amaninzi anikezela ngelayibrari ezinikeleyo ye-C # imizekelo, ehlelwe ngesihloko (i-syntax, iqoqo, i-I / O, i-OOP, njl.), Enokusebenza zombini njengezinto zokufunda kunye nesalathiso xa unamathele kwinto ethile.

IziBonelelo zokuFunda ezizezinye kunye noluntu

Ngaphandle kwamaxwebhu akudala kunye nezifundo ezisekwe kwiteksti, i-C # ecosystem izuza kwiseti etyebileyo yezifundo zevidiyo kunye nezixhobo eziqhutywa ngabahlali. Abafundi abaninzi bayathanda ukudibanisa izikhokelo ezibhaliweyo kunye noluhlu lokudlalwayo lukaYouTube okanye izifundo ezinde.

Ezinye ii-academy zamahhala kunye namaqonga abonisa umxholo ovela kubafundisi-ntsapho be-C # abaziwayo-njengoTim Corey kunye nabanye abadumileyo be-YouTubers-baququzelelwe kwizifundo kunye neetampu zexesha ukuze ukwazi ukutsiba ngqo kwisihloko osikhathaleleyo. Oku kuluncedo ngakumbi ukuba ukhetha incoko, isimbo sokufundisa sokwenyani.

Kukwaxhaphakile ukuba abaqalayo be-C # bakhuphele kwiilwimi eziyeleleneyo njengePython okanye iJavaScript kamva, kunye nengqondo yokusombulula ingxaki oyiphuhlisayo ngelixa usebenza nge-C # iya kuguqulela kakuhle kuzo zonke ezo nkqubo zendalo. Ukwabelana ngezifundo zakho ozithandayo, amajelo, okanye iibhlog nabanye kwaye ucele iingcebiso kumagqabantshintshi okanye iiforam kukunceda ufumane umxholo omtsha.

Ukusebenzisana noluntu-ngeesayithi ze-Q&A, iibhodi zengxoxo, okanye amaqela eencoko-kwenza kube lula kakhulu ukuhlala unomdla kwaye ungabambeki xa ubetha iikhonsepthi ezibhidayo.

Kufuneka wenze ntoni kwi-C # Code (kwaye xa unokutsiba ukuseta)

Enye yezinto eziluncedo ezininzi zale mihla ze-C # zokufundisa kukuba unokubaleka ikhowudi eninzi ngokuthe ngqo kwisikhangeli ngaphandle kokufaka nantoni na, egqibeleleyo ukuba uvavanya amanzi. Imizekelo esebenzisanayo iphatha ukuhlanganiswa kunye nokwenziwa emva kwemiboniso.

Nangona kunjalo, njengoko uqhubela phambili kwaye uqala ukusebenza kwiiprojekthi ezinokwenyani, ekugqibeleni uya kufuna ukuseta imeko-bume yophuhliso lwendawo ukuze ube nolawulo olupheleleyo kunye nokufikelela kwi-ecosystem epheleleyo ye.NET. Kwi-Windows kunye namanye amaqonga, oko kuthetha ukufaka i-.NET SDK kunye nomhleli ofanelekileyo okanye i-IDE.

Iingcebiso eziqhelekileyo ziquka iKhowudi ye-Visual Studio ene-C # izandiso (ezifana ne-C# Dev Kit) okanye i-IDE ye-Visual Studio epheleleyo kwi-Windows, zombini ezibonelela nge-IntelliSense, izixhobo zokucoca, kunye neetemplates zeprojekthi. KwiLinux okanye kwiMacOS, ungafaka kwakhona i-.NET SDK kunye neKhowudi yeVS kwaye ufezekise amava afanayo kakhulu.

Ukuba usebenzisa umatshini weWindows, ezinye ii-tutorials zide zibonelele nge-automated WinGet izikripthi zoqwalaselo ezifakela zonke izinto ezifunekayo kuwe, ukutsiba nantoni na esele ikwisistim yakho, ehambisa inkqubo yokuseta.

INyathelo-nge-Nyathelo ULungiselelo lweNdawo yeNdawo yeC#

Xa ulungele ukusuka kwi-browser-based learning ukuya kuphuhliso lwasekhaya lokwenyani, inkqubo ecetyiswayo iyahluka kancinci kuxhomekeke kwinkqubo yakho yokusebenza, kodwa amacandelo aphambili ayafana. Udinga i-.NET SDK, umhleli wekhowudi, kunye ne-C # izandiso.

Kwi-Windows, ezinye iiseti ezigciniweyo zisebenzisa ifayile yoqwalaselo yeWinGet eququzelela ukufakwa kwazo zonke izixhobo ezifunekayo. Ingcinga eqhelekileyo kukukhuphela loo fayile, nqakraza kabini, wamkele imigaqo yelayisensi (kaninzi ngokuchwetheza isiqinisekiso esifana no-y kwaye ucofe u-Enter), kwaye emva koko uvumele iskripthi sifake yonke into ngelixa uvuma nayiphi na i-akhawunti yoLawulo lweAkhawunti yoMsebenzisi.

Kumaqonga angengo-Windows, okanye ukuba ukhetha ulawulo lwezandla, ufaka izinto ngokwahlukeneyo: qala ubambe isifakeli esicetyiswayo se-NET SDK kwiphepha elisemthethweni lokhuphelo, emva koko ufumane iKhowudi yeVisual Studio kwiwebhusayithi yayo, kwaye ekugqibeleni ufake okanye uvule iC# Dev Kit okanye ulwandiso olulinganayo ukusuka ngaphakathi komhleli. Iwebhusayithi nganye ihlala ibona inkqubo yakho yokusebenza kwaye icebisa ukhuphelo olufanelekileyo ngokuzenzekelayo.

Nje ukuba yonke into isendaweni, ukwenza iprojekthi entsha yekhonsoli kuhlala kulula njengokusebenzisa i-dotnet entsha yomyalelo we-console (ukusuka kwi-terminal) okanye ukusebenzisa ithempleyithi yeprojekthi kwi-IDE yakho, ikunika indawo egcwele ngokupheleleyo yokwakha izicelo ezinkulu ze-C #.

Ngubani omele afunde i-C # kwaye zeziphi iimfuno ezifunekayo kuNcedo

I-C # ilungele uluhlu olubanzi lwabafundi: abaqalayo ngokupheleleyo, abafundi, isoftware kunye nabaphuhlisi bewebhu, abadali bemidlalo, kunye neengcali kwiindawo zamashishini. Ukudityaniswa kwayo kokufundeka kunye nobuchule kuyenza ibe lulwimi lokuqala oluluqilima kunye nolwimi lwesibini okanye lwesithathu oluxabisekileyo.

Ukuba ujolise kwi-ASP.NET backends, full-stack .NET work, okanye imidlalo yoManyano, C# sisenzo ekufuneka ubenaso. Kwakhona lukhetho olunyanzelisayo lophuhliso lweselula ngeXamarin okanye .NET MAUI kunye neemeko zokufunda ngomatshini usebenzisa izikhokelo ezifana neML.NET.

Awudingi ngokungqongqo amava okubhala ikhowudi ukuze uqalise, kodwa ukubamba isiseko semibono yenkqubo ngokubanzi-ezinje ngezinto eziguquguqukayo, iimeko, kunye neelophu-kungenza inkqubela phambili yakho yangethuba ilula. Ukuqhelana naluphi na ulwimi oluvela kusapho lwe-C (C, C ++, Java) kukunika intloko eyongezelelweyo isiqalo kuba i-syntax iya kubonakala iqhelekile.

Izinto eziyimfuneko eziluncedo ziquka ukucinga okunengqiqo, ukuvuma ukusombulula iingxaki inyathelo nenyathelo, kunye nekhompyutha ene-.NET SDK kunye nomhleli ofakiweyo (okanye ukufikelela kumqokeleli we-intanethi okanye indawo esebenzisanayo ukuba ufuna ukuhlehlisa ukuseta). Ukuqonda okusisiseko kweekhonsepthi ezijolise kwinto nazo ziya kuhlawula, kodwa izifundo ezininzi zichaza ezo zisuka ekuqaleni.

Izifundo ze-C # ezidibanisa iingcaciso ezicacileyo, imizekelo esebenzisanayo, uqheliselo olucwangcisiweyo, iikhwizi, kunye noseto oluthe ngcembe lokusingqongileyo kukunika umendo opheleleyo wokuprinta "Molo, Hlabathi!" ukwakha izicelo zokwenyani ezisebenza ngamanani, ingqokelela, iifayile, kunye noyilo olujolise kwinto, ke ukuba ulandela indlela enjalo ngokungaguquguqukiyo-ukulinga, ukwaphula kunye nokulungisa ikhowudi, kwaye uthembele kuluntu-uya kukhula ngokuthe ngcembe ukusuka kumqali onomdla ukuya kumthuthukisi we-C # oqinisekileyo ngezakhono eziguqulela ngqo kwiwebhu yanamhlanje, idesktop, umdlalo, kunye neeprojekthi zamafu.
