ToSByte Method (UInt64)

Convert.ToSByte Method (UInt64)

 

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

This API is not CLS-compliant.

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

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

Parameters

value
Type: System.UInt64

The 64-bit unsigned integer to convert.

Return Value

Type: System.SByte

An 8-bit signed integer that is equivalent to value.

Exception Condition
OverflowException

value is greater than SByte.MaxValue or less than SByte.MinValue.

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

ulong[] numbers = { UInt64.MinValue, 121, 340, UInt64.MaxValue };
sbyte result;

foreach (ulong number in numbers)
{
   try {
      result = Convert.ToSByte(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 SByte type.",
                        number.GetType().Name, number);
   }
}
// The example displays the following output:
//    Converted the UInt64 value 0 to the SByte value 0.
//    Converted the UInt64 value 121 to the SByte value 121.
//    The UInt64 value 340 is outside the range of the SByte type.
//    The UInt64 value 18446744073709551615 is outside the range of the SByte type.
