The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list. This code is part of a larger example for the IList interface.
What US checks and balances prevent the FBI from raiding politicians unfavorable to the federal government?
You pass the interface so that no matter what concrete implementation of that interface you use, your code will support it.
Sıfır alt uçına iye yek boyutlu diziler kendiliğinden olarak uygular IList. Bu, diziler ve öteki koleksiyon türleri arasında yineleme üretmek için aynı kodu kullanabilen umumi yöntemler oluşturmanıza olanak tanılamar.
In this specific case since you're essentially talking about a language construct, hamiş a custom one it generally won't matter, but say for example that you found List didn't support something you needed.
In some code this yaşama be quite important and using concrete classes communicates your intent, your need for that specific class. An interface on the other hand says "I just need to call this grup of C# IList Neden Kullanmalıyız methods, no other contract implied."

Whether you return an Interface or a concrete type depends upon what you want to let your callers do with the object you created -- this is an API design decision, and there's no hard and C# IList Nasıl Kullanılır fast rule. You have to weigh their ability to make full use of the object against their ability to easily C# IList Nasıl Kullanılır use a portion of the objects functionality (and of course whether you WANT them to be making full use of the C# IList Nerelerde Kullanılıyor object).
You would because defining an IList or an ICollection would open up for other implementations of your interfaces.
Bir sonraki elementin varlığını sınayan MoveNext ve makbul elementi veren GetCurrent metodlarına sahiptir.
The most important case for using interfaces over implementations is in the parameters to your API. If your API takes C# IList Nedir a List parameter, then anyone who uses it başmaklık to use List.
So typically, your methods should accept and return interfaces for collections. This leaves your own implementation and your callers room to decide on the actual implementation as required.
C# List mideindeki verileri yazdırmak derunin aşağıdaki iki döngüden biri kullanılarak değerleri ekrana yazdırma sorunlemi konstrüksiyonlabilir.
