I am looking for a framework-defined interface that declares indexer. In other words, I am looking for something like this:

public interface IYourList<T>
    {
        T this[int index] { get; set; }
    }

I just wonder whether .Net framework contains such interface? If yes, what is it called?

You might ask why I can't just create the interface myself. Well, I could have. But if .Net framework already has that why should I reinvent the wheel?
