Important

This API is not CLS-compliant.

CLS-compliant alternative
System.Decimal.ToInt16(Decimal)

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

public:
 static System::SByte ToSByte(System::Decimal value);
[System.CLSCompliant(false)]
public static sbyte ToSByte(decimal value);
[<System.CLSCompliant(false)>]
static member ToSByte : decimal -> sbyte
Public Shared Function ToSByte (value As Decimal) As SByte

Parameters

value
Decimal

The decimal number to convert.

Returns

SByte

An 8-bit signed integer equivalent to value.

Attributes
CLSCompliantAttribute

Exceptions

OverflowException

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

Examples

The following example uses the ToSByte method to convert decimal numbers to SByte values.

using System;

class Example
{
   public static void Main( )
   {
      decimal[] values = { 123m, new Decimal(78000, 0, 0, false, 3),
                           78.999m, 255.999m, 256m,
                           127.999m, 128m, -0.999m,
                           -1m,  -128.999m, -129m };

      foreach (var value in values) {
         try {
            sbyte number = Decimal.ToSByte(value);
            Console.WriteLine("{0} --> {1}", value, number);
         }
         catch (OverflowException e)
         {
             Console.WriteLine("{0}: {1}", e.GetType().Name, value);
         }
      }
   }
}
// The example displays the following output:
//     78 --> 78
//     78.000 --> 78
//     78.999 --> 78
//     OverflowException: 255.999
//     OverflowException: 256
//     127.999 --> 127
//     OverflowException: 128
//     -0.999 --> 0
//     -1 --> -1
//     -128.999 --> -128
//     OverflowException: -129

open System

let values = 
    [ 123m; Decimal(78000, 0, 0, false, 3uy)
      78.999m; 255.999m; 256m
      127.999m; 128m; -0.999m
      -1m; -128.999m; -129m ]

for value in values do
    try
        let number = Decimal.ToSByte value
        printfn $"{value} --> {number}"
    with :? OverflowException as e ->
        printfn $"{e.GetType().Name}: {value}"

// The example displays the following output:
//     78 --> 78

//     OverflowException: 128
//     -0.999 --> 0
//     -1 --> -1
//     -128.999 --> -128
//     OverflowException: -129

Module Example
   Public Sub Main()
      Dim values() As Decimal = { 78d, New Decimal(78000, 0, 0, false, 3), 
                                  78.999d, 255.999d, 256d,

                                  -1d,  -128.999d, -129d }

      For Each value In values
         Try
            Dim number As SByte = Decimal.ToSByte(value)
            Console.WriteLine("{0} --> {1}", value, number)       
         Catch e As OverflowException
             Console.WriteLine("{0}: {1}", e.GetType().Name, value)
         End Try   
      Next
   End Sub
End Module

Remarks

You can also convert a Decimal value to an 8-bit signed integer by using the Explicit assignment operator. Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
