Decimal Explicit Conversion (Decimal to SByte)

Converts a Decimal to an 8-bit signed integer.

This API is not CLS-compliant. The CLS-compliant alternative is ToInt16(Decimal).

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

public static explicit operator sbyte (
	decimal value
)

Parameters

value
Type: System.Decimal
The value to convert.

Return Value

Type: System.SByte
An 8-bit signed integer that represents the converted Decimal.

ExceptionCondition
OverflowException

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 code example converts Decimal numbers to SByte values using the explicit Decimal to SByte conversion.


// Example of the explicit conversions from decimal to byte and 
// decimal to sbyte.
using System;

class DecimalToS_ByteDemo
{
    const string formatter = "{0,16}{1,19}{2,19}";

    // Get the exception type name; remove the namespace prefix.
    public static string GetExceptionType( Exception ex )
    {
        string exceptionType = ex.GetType( ).ToString( );
        return exceptionType.Substring( 
            exceptionType.LastIndexOf( '.' ) + 1 );
    }

    // Convert the decimal argument; catch exceptions that are thrown.
    public static void DecimalToS_Byte( decimal argument )
    {
        object SByteValue;
        object ByteValue;

        // Convert the argument to an sbyte value.
        try
        {
            SByteValue = (sbyte)argument;
        }
        catch( Exception ex )
        {
            SByteValue = GetExceptionType( ex );
        }

        // Convert the argument to a byte value.
        try
        {
            ByteValue = (byte)argument;
        }
        catch( Exception ex )
        {
            ByteValue = GetExceptionType( ex );
        }

        Console.WriteLine( formatter, argument, 
            SByteValue, ByteValue );
    }

        Console.WriteLine( formatter, "decimal argument", 
            "sbyte/exception", "byte/exception" );
        Console.WriteLine( formatter, "----------------", 
            "---------------", "--------------" );

        // Convert decimal values and display the results.
        DecimalToS_Byte( 78M );
        DecimalToS_Byte( new decimal( 78000, 0, 0, false, 3 ) );
        DecimalToS_Byte( 78.999M );
        DecimalToS_Byte( 255.999M );
        DecimalToS_Byte( 256M );
        DecimalToS_Byte( 127.999M );
