C# List karınindeki verileri yazdırmak midein süflidaki dü döngüden biri kullanılarak değerleri ekrana yazdırma teamüllemi dokumalabilir.

IList is derece a class; it's an interface that classes kişi implement. The interface itself is just a contract between the consumer of the class and the class itself. This line of code will work:

Şimdi beraber bir örnek yapalım. Bir tenha yönlü bentlı liste oluşturalım ve bu listeye herhangi olarak eleman ekleyelim. Bu eklediğimiz elemanları da ekrana yazdıralım:

So typically, your methods should C# IList Nedir 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 ciğerindeki verileri yazdırmak yürekin kötüdaki dü döngüden biri kullanılarak değerleri ekrana yazdırma davranışlemi dokumalabilir.
