Answer 1

interesting question, here's one solution. You have to add an indexer for every key type you want to support though.

public class NewDic
{
    public void Add(string key1, long key2, T value)
    {
        mDic.Add(key1, value);
        mDic.Add(key2, value);
    }

    public T this[string s]
    {
        get { return mDic[s]; }
    }

    public T this[long l]
    {
        get { return mDic[l]; }
    }


    Dictionary mDic = new Dictionary();
}

        NewDic dic = new NewDic();

        dic.Add("abc", 20, 10);

        Console.WriteLine(dic["abc"]);
        Console.WriteLine(dic[20]);
