Hashtable mylist = new Hashtable();
            mylist.Add("1", "100");

            mylist.Add("2", "200");

            mylist.Add("3", "300");

            IDictionaryEnumerator myEnumerator = mylist.GetEnumerator();

            while (myEnumerator.MoveNext())

            {

               res += myEnumerator.Key + ":" + myEnumerator.Value+";";

            }
