      byteString = "0x1F";

   private static void CallTryParse(string stringToConvert, NumberStyles styles)
   {  
      Byte byteValue;
      bool result = Byte.TryParse(stringToConvert, styles, 
                                  null as IFormatProvider, out byteValue);
      if (result){
         Console.WriteLine("Converted '{0}' to {1}",stringToConvert, byteValue);
      }else{
         Console.WriteLine("Attempted conversion of '{0}' failed.", stringToConvert.ToString());
