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

Performans Optimizasyonu: IList, bilgi erişimini optimize ederek uygulamanın performansını zaitrabilir ve yeti yönetimini iyileştirebilir.

I think that, ideally, the .NET Framework would include a static sorting method that accepts an IList, but the next best thing is to create your own extension method. It's not too hard to create a couple of methods that will allow you to sort an IList birli you would a List.

Hayat a unique position be deduced if pieces are replaced by checkers (dirilik see piece color but not type)

In this specific case since you're essentially talking about a language construct, not a custom one it generally won't matter, but say for example that you found List didn't support something you needed.

List is a specific implementation of IList, which is a container that can be addressed the same way as a linear array T[] using an integer index. When you specify IList bey the type of the method's argument, you only specify that you need certain capabilities of the container. For example, the interface specification does derece enforce a specific veri structure to be used.

I thought I'd never need to change from a List but had to later change to use a custom list library for the extra functionality it provided. Because I'd only returned an IList none of the people that used the library had to change their code.

Then later if you decide to convert the actual data store from a List to a Dictionary and expose the dictionary keys as the actual value for the property (I have C# IList Kullanımı had to do exactly this before). Then consumers who have come to expect that their changes will be reflected inside of your class will no longer have that capability. That's C# IList Nedir a big sorun! If you expose the List birli an IEnumerable you sevimli comfortably predict that your collection is derece being modified externally.

Benefit of using an Interface is that you get to implement your functionality or C# IList Kullanımı better yet, the only functionality you require. So, if iteration/enumeration is required only, then there is no need for the Sort, Add methods.

If you use the concrete type all callers need to be updated. If exposed as IList the caller doesn't have to be changed.

I read a lot of posts saying how this makes it easier to change the implementation later on, but I just don't fully see how that works.
