Else use List. You kişi't really argue "oh but I KNOW that I will always pass in a List here", then you should take a List not an IList, else you are breaking Liskov substitution principle: "if S is a subtype of T, then objects of type T may be replaced with objects of type S"

1 @supercat: What could ISortableList offer that's hamiş already in IList? Or, asked differently, why couldn't an IList be sorted in-place without re-adding the items by your imagined static method?

If a class implmenting IList needs to be extended or changed, the consuming code does derece have to change; it knows what the IList Interface contract adheres to.

; being aware of the definition of the interface ie. all abstract methods that are there to be implemented by any class inheriting the interface. so if some one makes a huge class of his own with several methods C# IList Nedir besides the ones he inherited from the interface for some addition functionality, and those are of no use to you, its better to use a reference to a subclass (in this case the interface) and assign the concrete class object to it.

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 had to do exactly this before).
