The following example attempts to convert each element in an array of Char values to a signed byte.

char[] chars = { 'a', 'z', '\u0007', '\u0200', '\u1023' };
foreach (char ch in chars)
{
   try {
      sbyte result = Convert.ToSByte(ch);
      Console.WriteLine("{0} is converted to {1}.", ch, result);
   }   
   catch (OverflowException) {
      Console.WriteLine("Unable to convert u+{0} to a byte.",
                        Convert.ToInt16(ch).ToString("X4"));
   }
}   
// The example displays the following output:
//    a is converted to 97.
//    z is converted to 122.
//     is converted to 7.
//    Unable to convert u+00C8 to a byte.
//    Unable to convert u+03FF to a byte.
