         Dim id As Integer = 1
         Dim subString As String
         For Each subString In theRegex.Split(s1)
             id = id + 1
             sBuilder.AppendFormat("{0}: {1}" & Environment.NewLine, id, subString)
         Next subString
         Console.WriteLine("{0}", sBuilder)
     End Sub
 End Class
