string AString = "Ting, Choo";
string[] tokens = AString.Split(new char[] { ',' });
MessegeBox.Show(takens[0]);  //==>NO PROBLEM
MessegeBox.Show(takens[1]); // ==>ERROR : out of index..

This is very ignoring, to overcome this error for Whidbey Beta 2,
instead of using tokens[1], i did this
   string token2 = AString.Replace(tokens[0]);

As i explore more in Whidbey 2, i have found countless of errors / mistakes which draw me to "uneffective" solutions..
What say u?
