It's always best to use the lowest base type possible. This gives the implementer of your interface, or consumer of your method, the opportunity to use whatever they like behind the scenes.

If you think that interfaces are useful only for building over-sized, grandiose architectures and have no place in small shops, then I hope that the person sitting across from you in the interview isn't me.

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.

However using a concrete implementation and List on a class that changes, could cause C# IList Neden Kullanmalıyız the calling code to need to be changed birli well. This is because a class adhering to IList guarantees a certain behavior that is not guaranteed by a concrete type using List. Also having the power to do something like modify the default C# IList Nasıl Kullanılır implementation of List on a class Implementing IList for say the .Add, .Remove or any other IList method gives the developer a lot

In VS2008, when I click on the service reference and C# IList Kullanımı select "Configure Service Reference", C# IList Nerelerde Kullanılıyor there is an option to choose how the client de-serializes lists returned from the service.

It really comes down to the kind of functionality you need. I'd suggest using the List class in most cases. IList is best for when you need to make a custom array that could have some very specific rules that you'd like to encapsulate within a collection so you don't repeat yourself, but still want .NET to recognize it birli a list.

Of course that only need apply to methods that are externally visible (i.e. public methods). I personally use interfaces even in internal code, but as you are able to change all the code yourself if you make breaking changes it's derece strictly necessary.

Coming soon: Throughout 2024 we will be phasing out GitHub Issues birli the feedback mechanism for content and replacing it with a new feedback system. For more information see: .

I have two ILists of the same type returned by NHibernate C# IList Kullanımı and have emerged the two IList into one, hence the need for sorting.

Bu şekilde, Dog dershaneı IAnimal interface’inin sözleşmesine uymuş evet. Aynı şekilde, özge hayvan sınıfları da IAnimal interface’ini uygulayabilir. Örneğin, adidaki kodda bir Cat dershaneı tanımladım ve IAnimal interface’ini uyguladım.
