Convert.ToUInt64 Method (SByte)

Converts the value of the specified 8-bit signed integer to the equivalent 64-bit unsigned integer.

This API is not CLS-compliant. 

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

[CLSCompliantAttribute(false)]
public static ulong ToUInt64(
	sbyte value
)

Parameters

value
Type: System.SByte
The 8-bit signed integer to convert.

Return Value

Type: System.UInt64
A 64-bit unsigned integer that is equivalent to value.

ExceptionCondition
OverflowException

value is less than zero.

The following example attempts to convert each element in a signed byte array to an unsigned long integer.


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

foreach (sbyte number in numbers)
{
   try {
      result = Convert.ToUInt64(number);
      Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                        number.GetType().Name, number,
                        result.GetType().Name, result);
   }
   catch (OverflowException) {
      Console.WriteLine("The {0} value {1} is outside the range of the UInt64 type.",
                        number.GetType().Name, number);
   }   
}
// The example displays the following output:
//    The SByte value -128 is outside the range of the UInt64 type.
//    The SByte value -1 is outside the range of the UInt64 type.
//    Converted the SByte value 0 to the UInt64 value 0.
//    Converted the SByte value 10 to the UInt64 value 10.
//    Converted the SByte value 127 to the UInt64 value 127.
