Decimal Explicit Conversion (Decimal to SByte)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.


Defines an explicit conversion of a Decimal to an 8-bit signed integer.

This API is not CLS-compliant.

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

public static explicit operator sbyte (
	decimal value


Type: System.Decimal

The value to convert.

Return Value

Type: System.SByte

An 8-bit signed integer that represents the converted Decimal.

Exception Condition

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

This operator supports the explicit conversion of a Decimal to a SByte. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to a Byte and an SByte value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the ToSByte method or the Convert.ToSByte(Decimal) method.

The following example converts Decimal numbers to SByte values by using the explicit Decimal to SByte conversion.

using System;

class Example
    public static void Main()
        // Define an array of decimal values.
       decimal[] values = { 78m, 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 byteValue = (SByte) value;
              Console.WriteLine("{0} ({1}) --> {2} ({3})", value,
                                value.GetType().Name, byteValue, 
           catch (OverflowException) {
              Console.WriteLine("OverflowException: Cannot convert {0}",
// The example displays the following output:
//       78 (Decimal) --> 78 (SByte)
//       78.000 (Decimal) --> 78 (SByte)
//       78.999 (Decimal) --> 78 (SByte)
//       OverflowException: Cannot convert 255.999
//       OverflowException: Cannot convert 256
//       127.999 (Decimal) --> 127 (SByte)
//       OverflowException: Cannot convert 128
//       -0.999 (Decimal) --> 0 (SByte)
//       -1 (Decimal) --> -1 (SByte)
//       -128.999 (Decimal) --> -128 (SByte)
//       OverflowException: Cannot convert -129
