Hashtable with MultiDimensional Key in C#

Question

I\'m basically looking for a way to access a hashtable value using a two-dimensional typed key in c#.

Eventually I would be able to do something like this

Answer 1

How about using a regular Dictionary with some kind of Tuple structure as a key?

public class TwoKeyDictionary
{
    private readonly Dictionary, V> _dict;

    public V this[K1 k1, K2 k2]
    {
        get { return _dict[new Pair(k1,k2)]; }
    }

    private struct Pair
    {
        public K1 First;
        public K2 Second;

        public override Int32 GetHashCode()
        {
            return First.GetHashCode() ^ Second.GetHashCode();
        }

        // ... Equals, ctor, etc...
    }
}
