Hey Bill!

For using KeyValuePair in SortedSet, you need to define IComparable for it. Until it's not there, SortedSet would not be able to work on the datatype (as inherently it is supposed to sort)

To see what I say, comment your ElementAt line and run the code. You will get a runtime error as "At least one object must implement IComparable."

UPDATE: Below sample works fine with ElementAt. Where is the gap?

Once we have a defined sorted data, we can access with ElementAt. I put up a quick example:
class SortedSetDemo
{
    static void Main(string[] args)
    {
        var words = new string[]
            {"the", "quick", "brown", "fox", "jumps",
             "over", "the", "lazy", "dog"};

        // Create a sorted set.
        var wordSet2 = new SortedSet<KeyValuePair<int, string>>(new KVPKeyComparer<int, string>());
        int x = 0;
        foreach (string word in words)
        {
            x++;
            wordSet2.Add(new KeyValuePair<int, string>(x, word));
        }

        // List the members of the sorted set.
        Console.WriteLine("Set items in sorted order:");

        // Access an item at a specified index (position).
        for (int j = 0; j < wordSet2.Count; j++)
        {
            var item = wordSet2.ElementAt(j);
            Console.WriteLine(item);
        }
    }

    public class KVPKeyComparer<TKey, TValue> : IComparer<KeyValuePair<TKey, TValue>> where TKey : IComparable
    {
        public int Compare(KeyValuePair<TKey, TValue> x, KeyValuePair<TKey, TValue> y)
        {
            if(x.Key == null)
            {
                if(y.Key == null)
                    return 0;
                return -1;
            }

            if(y.Key == null)
                return 1;

            return x.Key.CompareTo(y.Key);
        }
    }
}
Outputs:
[1, the]
[2, quick]
[3, brown]
[4, fox]
[5, jumps]
[6, over]
[7, the]
[8, lazy]
[9, dog]
