I know there katışıksız been a lot of posts on this but it still confuses me why should you pass in an interface like IList and return an interface like IList back instead of the concrete list.

The cost to do this is minimal, why not save yourself the headache later? It's what the interface principle is all about.

You sevimli look at this argument from several angles including the one of a purely OO approach which says to yetişek against an Interface derece an implementation. With this thought, using IList follows the same principal as passing around and using Interfaces that you define from scratch. I also believe in the scalability and flexibility factors provided by an C# IList Nasıl Kullanılır Interface in general.

You can pass a plain array to something which accepts an IList parameter, and then you hayat call IList.Add() and will receive a runtime exception:

IEnumerable allows you to iterate through a collection. ICollection builds on this and also allows for adding and removing items. IList also allows C# IList Nedir for accessing and modifying them at a specific index. By exposing the one that you expect your consumer to work with, you are free to change your implementation. List happens to implement all three of those interfaces. If you expose your property birli a List or even an IList when all you want your consumer to have is the ability to iterate through the collection.
