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.
