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)

Public Shared Function ToSByte (
	value As ULong
) As SByte

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.

Dim numbers() As ULong = { UInt64.MinValue, 121, 340, UInt64.MaxValue }
Dim result As SByte
For Each number As ULong 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 e As OverflowException
      Console.WriteLine("The {0} value {1} is outside the range of the SByte type.", _
                        number.GetType().Name, number)
   End Try
Next
' 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.
