Here's a simple example demonstrating the creation of a comma delimited string using String.Join() from a list of Strings:

List histList = new List();
histList.Add(dt.ToString("MM/dd/yyyy::HH:mm:ss.ffff"));
histList.Add(Index.ToString());
/*arValue is array of Singles */
foreach (Single s in arValue)
{
     histList.Add(s.ToString());
}
String HistLine = String.Join(",", histList.ToArray());
