   End Try

   ' A conversion from Char to Long cannot overflow.
   longVal = System.Convert.ToInt64(charVal)
   outputBlock.Text &= String.Format("{0} as a Long is {1}", _
                             charVal, longVal) & vbCrLf
End Sub

public void ConvertLongChar(long longVal)
{
   char charVal = 'a';

   try
   {
      charVal = System.Convert.ToChar(longVal);

   }
   catch (System.OverflowException)
   {
      outputBlock.Text += String.Format(
         "Overflow in long-to-char conversion.") + "\n";
   }

   // A conversion from Char to long cannot overflow.
   longVal = System.Convert.ToInt64(charVal);
   outputBlock.Text += String.Format("{0} as an Int64 is {1}",
