how to write a function to take any object with an index operator

I've never seen any usage like that. But I just wonder if it is possible to make an implementation like bleow. I know that it's not working. But I mean a similar usage if exist.

public T this<T>[T param]
{
    get 
    {
        ....
    }
}

It is possible using an interface `public interface IIndexable { T this[I index] { get; set; } }` and adding this to your method/class `where T : class, IEnumerableExtensions.IIndexable` — DerpyNerd, Nov 18 '16 at 08:01

No, generic properties, and indexers (a property), aren't possible.
