public static long ToInt64(
	sbyte value


Type: System.SByte

The 8-bit signed integer to convert.

Return Value

Type: System.Int64

A 64-bit signed integer that is equivalent to value.

The following example converts each element in a signed byte array to a long integer.

sbyte[] numbers = { SByte.MinValue, -1, 0, 10, SByte.MaxValue };
long result;

foreach (sbyte number in numbers)
   result = Convert.ToInt64(number);
   Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                     number.GetType().Name, number,
                     result.GetType().Name, result);
// The example displays the following output:
//       Converted the SByte value -128 to the Int64 value -128.
//       Converted the SByte value -1 to the Int64 value -1.
//       Converted the SByte value 0 to the Int64 value 0.
//       Converted the SByte value 10 to the Int64 value 10.
//       Converted the SByte value 127 to the Int64 value 127.
