public static char ToChar(
	ulong value


Type: System.UInt64
The 64-bit unsigned integer to convert.

Return Value

Type: System.Char
A Unicode character that is equivalent to value.


value is greater than Char.MaxValue.

The following example converts each element in an array of unsigned long integers to a Char value.

ulong[] numbers = { UInt64.MinValue, 40, 160, 255, 1028,
                    2011, 30001, 207154, Int64.MaxValue };
char result;
foreach (ulong number in numbers)
   try {
      result = Convert.ToChar(number);
      Console.WriteLine("{0} converts to '{1}'.", number, result);
   catch (OverflowException) {
      Console.WriteLine("{0} is outside the range of the Char data type.",
// The example displays the following output:
//       0 converts to ' '.
//       40 converts to '('.
//       160 converts to ' '.
//       255 converts to 'ÿ'.
//       1028 converts to '?'.
//       2011 converts to '?'.
//       30001 converts to '?'.
//       207154 is outside the range of the Char data type.
//       9223372036854775807 is outside the range of the Char data type.
