Perhaps a search function might?
If the Interface was "media objects", then a static collection of all TV, audio, and movies, and a search function to return the Program / song / movie with a given name?

Solution 3

Anything that's heriarchical might do this, so say you have a tree structure of categories (or a tree structure of anything) then you might have a method to get an item's parent;

C#

public interface ICategory
{
    string Name { get; set; }
    IEnumerable<ICategory> SubCategories { get; set; }
    ICategory Parent { get; set; }
}

This looks great. Can I have a small example to understand the real life implementation ? Any link out there might help.
