Feem ntau ntawm cov txheej txheem hauv qhov no chav kawm txhais tau tias yog txoj kev txuas ntxiv uas txuas ntxiv mus IEnumerable . Qhov no txhais tau tias lawv tuaj yeem raug hu ua ib qho piv txwv ntawm txhua yam khoom siv IEnumerable . Cov txheej txheem uas siv rau hauv cov lus nug uas xa rov qab tus nqi singleton ua haujlwm thiab haus cov ntaub ntawv lub hom phiaj tam sim ntawd.
Yog li, dab tsi yog chav kawm suav nrog hauv C #?
IEnumerable thiab IEnumerator yog qhov kev siv ntawm iterator qauv hauv. NET. Hauv C# , tag nrho cov ntawv sau (xws li cov npe, phau ntawv txhais lus, pawg, kab, thiab lwm yam) yog suav tau vim lawv siv cov IEnumerable interface. Yog li cov hlua. Koj tuaj yeem iterate hla ib txoj hlua siv lub foreach block kom tau txhua tus cim hauv txoj hlua.
Kuj Paub, thaum twg peb yuav siv IEnumerable hauv C#? IEnumerable interface yog siv thaum peb xav rau iterate ntawm peb cov chav kawm siv lub foreach voj. Cov IEnumerable interface muaj ib txoj kev, GetEnumerator, uas rov qab IEnumerator interface uas pab peb rau iterate ntawm cov chav kawm siv lub foreach voj.
Ntawm no, IEnumerator yog dab tsi hauv C# nrog piv txwv?
IEnumerable yog ib qho interface uas txhais tau ib txoj kev GetEnumerator() uas rov qab ib qho IEnumerator interface. Qhov no ua haujlwm rau kev nyeem tsuas yog nkag mus rau ib phau ntawv uas siv IEnumerable tuaj yeem siv nrog cov lus qhia. IEnumerator muaj ob txoj hauv kev MoveNext thiab Reset. Nws kuj muaj ib qho cuab yeej hu ua Tam sim no.
Icollection hauv C# yog dab tsi?
Cov Kev sau interface hauv C# txhais qhov loj me, tus lej, thiab cov txheej txheem synchronization rau tag nrho cov kev sau tsis zoo. Nws yog lub hauv paus interface rau cov chav kawm hauv System. Collections namespace.

Dab tsi yog qhov txawv ntawm chav kawm sab hauv thiab cov chav nested?
Cov chav kawm uas tau tshaj tawm yam tsis siv qhov zoo li qub yog hu ua chav kawm sab hauv lossis chav kawm tsis zoo li qub. Cov chav kawm Staticnested yog chav kawm zoo li lwm cov tswv cuab zoo li qub ntawm cov chav kawm sab nrauv. Txawm li cas los xij, cov chav kawm sab hauv yog khi toinstance thiab nws tuaj yeem nkag mus rau cov tswv cuab ntawm pawg enclosingclass
Dab tsi yog ob chav kawm tshwj xeeb hauv hierarchy ntawm Java zam chav kawm?
Chav Kawm Exception muaj ob lub ntsiab subclasses: IOException class thiab RuntimeException Class. Hauv qab no yog cov npe ntawm feem ntau kuaj xyuas thiab tsis tau txheeb xyuas Java's Built-in Exceptions
Peb puas tuaj yeem muaj ntau chav kawm pej xeem hauv chav kawm hauv Java?
Yog, nws ua tau. Txawm li cas los xij, muaj peev xwm tsuas yog ib pawg pej xeem ib. java cov ntaub ntawv, raws li publicclasses yuav tsum muaj tib lub npe raws li cov ntaub ntawv qhov chaw. OneJava cov ntaub ntawv tuaj yeem muaj ntau chav kawm nrog kev txwv uas tsuas yog ib qho ntawm lawv tuaj yeem ua pej xeem
Chav kawm piav qhia txog tus qauv ntawm chav kawm yog dab tsi?
Nyob rau hauv object-oriented programming, ib chav kawm yog ib tug template txhais ntawm txoj kev s thiab txawv txawv s nyob rau hauv ib tug tej yam khoom. Yog li, ib yam khoom yog ib qho piv txwv tshwj xeeb ntawm chav kawm; nws muaj cov txiaj ntsig tiag tiag tsis yog hloov pauv. Cov qauv ntawm ib chav kawm thiab nws cov subclasses yog hu ua chav kawm hierarchy
Dab tsi yog qhov tseem ceeb ntawm IT Essentials chav kawm muaj nyob hauv Cisco Academy cov ntaub ntawv kawm?
Dab tsi yog qhov tseem ceeb ntawm IT Essentials chav kawm muaj nyob hauv Cisco Academy cov ntaub ntawv kawm? Nws qhia cov neeg kawm paub txog cov hauv paus ntawm lub computer hardware thiab software. Lub zej zog IT twg yog kev sau cov peev txheej tsim los rau cov tib neeg uas xav tsim kev txawj ntse thiab ua raws li Cisco ntawv pov thawj?
