C#

Dictionary<string, double> d = new Dictionary<string, double>();

           d.Add("z", 1);
           d.Add("a", 2);
           d.Add("c", 3);
           d.Add("b", 4);

           foreach (KeyValuePair<string, double> k in d)
           {
               Console.WriteLine(k.Key + " " + k.Value);
           }



           KeyValuePair<string, double> i_item = d.ElementAt(2);

           int myIndex = Array.IndexOf(d.Keys.ToArray<string>(), "a");

private int theIndex;
//
theIndex = dictionaryStringInt.Keys.ToList<string>().IndexOf("KeyString");

The order of the keys in the Dictionary<tkey, tvalue="">.KeyCollection is unspecified

Of more interest, and something I actually intend to explore, is what happens when have compound structures with KeyValue pairs, and both Key and Value Types are complex classes, not just ValueTypes.
