Convert.ToSByte Method (Int16)

Converts the value of the specified 16-bit signed integer to the equivalent 8-bit signed integer.

This API is not CLS-compliant. 

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

<CLSCompliantAttribute(False)> _
Public Shared Function ToSByte ( _
	value As Short _
) As SByte


Type: System.Int16

The 16-bit signed integer to convert.

Return Value

Type: System.SByte
An 8-bit signed integer that is equivalent to value.


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

The following example attempts to convert each element in an array of signed 16-bit integers to a signed byte.

Dim numbers() As Short = { Int16.MinValue, -1, 0, 121, 340, Int16.MaxValue }
Dim result As SByte 
For Each number As Short In numbers
      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 
' The example displays the following output: 
'    The Int16 value -32768 is outside the range of the SByte type. 
'    Converted the Int16 value -1 to the SByte value -1. 
'    Converted the Int16 value 0 to the SByte value 0. 
'    Converted the Int16 value 121 to the SByte value 121. 
'    The Int16 value 340 is outside the range of the SByte type. 
'    The Int16 value 32767 is outside the range of the SByte type.
