ToByte Method

Decimal.ToByte Method (Decimal)

 

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

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

public static byte ToByte(
	decimal value
)

Parameters

value
Type: System.Decimal

The decimal number to convert.

Return Value

Type: System.Byte

An 8-bit unsigned integer equivalent to value.

Exception Condition
OverflowException

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

Parameter value is rounded to the nearest integer value toward zero, and that result is returned.

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

The following example uses the ToByte method to convert decimal numbers to Byte 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 {
            byte number = Decimal.ToByte(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
//     255.999 --> 255
//     OverflowException: 256
//     127.999 --> 127
//     128 --> 128
//     -0.999 --> 0
//     OverflowException: -1
//     OverflowException: -128.999
//     OverflowException: -129
