I toyed with writing an extension method, also with inheriting from IList and implementing my own Sort() method bey well kakım casting to a List but none of these seemed overly elegant.

For instance I was switching one of my return types to a IList then I well I am probably just going to enumerate over them anyways lets just return an IEnumberable.

Typically, a good approach is to use IList in your public facing API (when appropriate, and list semantics are needed), and then List internally to implement the API. This allows you to change to a different implementation of IList without breaking code that uses your class.

Yes, you may never change that veri type from a List but you birey be sure that if you have to. Your code is ready for it.

In case of using IList, the caller is always guareented things to work, and the implementer is C# IList Nerelerde Kullanılıyor free to change the underlying collection to any alternative concrete implementation of IList

If you specify your methods to return an interface that means you are free to change the exact implementation later on without the consuming method ever knowing.

If you started with a concrete type and you decided to change to another one, even if it uses the same interface, you're going to break someone else's code unless you started off with an interface or abstract base type. Share Improve this answer Follow

If you can consider your C# IList Nerelerde Kullanılıyor method, determine that you probably won't be changing the return collection type, then it is probably safe to return a more exact type.

Bu örnekte, Student adında bir dershane ve StudentCollection isminde CollectionBase derslikından türeyen özel bir C# IList Nerelerde Kullanılıyor derlem dershaneı oluşturduk.

If you use a concrete implementation of list, another implementation of the same list will hamiş be supported by your code.

Bu şekilde, Dog derslikı IAnimal interface’inin sözleşmesine uymuş olabilir. Aynı şekilde, diğer efsanevi sınıfları da IAnimal interface’ini C# IList Neden Kullanmalıyız uygulayabilir. Örneğin, süflidaki kodda bir Cat derslikı tanımladım ve IAnimal interface’ini uyguladım.
