Decimal Explicit Conversion (Decimal to Byte)

 
equivalentCodeEntityM:System.Decimal.ToByte(System.Decimal)

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

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

public static explicit operator byte (
	decimal value
)

Parameters

value
Type: System.Decimal

The value to convert.

Return Value

Type: System.Byte

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

Exception Condition
OverflowException

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

This operator supports the explicit conversion of a Decimal to a Byte. 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 value by using C#, Visual Basic, and C++. To perform a conversion that is independent of language, you can call the Decimal.ToByte or the Convert.ToByte(Decimal) method.

The following example converts Decimal numbers to Byte values by using the explicit Decimal to Byte 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 {     
              Byte byteValue = (Byte) value;
              Console.WriteLine("{0} ({1}) --> {2} ({3})", value,
                                value.GetType().Name, byteValue, 
                                byteValue.GetType().Name);
           }
           catch (OverflowException) {
              Console.WriteLine("OverflowException: Cannot convert {0}",
                                value);
           }
       } 
    }
}
// The example displays the following output:
//       78 (Decimal) --> 78 (Byte)
//       78.000 (Decimal) --> 78 (Byte)
//       78.999 (Decimal) --> 78 (Byte)
//       255.999 (Decimal) --> 255 (Byte)
//       OverflowException: Cannot convert 256
//       127.999 (Decimal) --> 127 (Byte)
//       128 (Decimal) --> 128 (Byte)
//       -0.999 (Decimal) --> 0 (Byte)
//       OverflowException: Cannot convert -1
//       OverflowException: Cannot convert -128.999
//       OverflowException: Cannot convert -129
