Decimal.ToByte() Method in C#

Last Updated : 11 Jul, 2025

This method is used to converts the value of the specified Decimal to the equivalent 8-bit unsigned integer.

Syntax: public static byte ToByte (decimal a); Parameter: a: This parameter specifies the decimal which will be negated. Return Value: An 8-bit unsigned integer equivalent to a will be returned.
Exception:

This method will give

OverflowException

if the value i.e.

a

is less than MinValue or greater than MaxValue. Below programs illustrate the use of

Decimal.ToByte(Decimal) Method

:

Example 1: csharp 
// C# program to demonstrate the
// Decimal.ToByte(Decimal) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        try {

            // Declaring the decimal variable
            Decimal a = 127.97m;

            // using ToByte() method;
            byte value = Decimal.ToByte(a);

            // Display the byte value
            Console.WriteLine("The Byte value "+
                             "is : {0}", value);
        }

        catch (OverflowException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
Output: 
The Byte value is : 127
Example 2: csharp 
// C# program to demonstrate the
// Decimal.ToByte(Decimal) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        try {

            // Declaring the decimal variable
            Decimal a = -0.999m;

            // using ToByte() method;
            byte value = Decimal.ToByte(a);

            // Display the byte value
            Console.WriteLine("The Byte value"+
                           " is : {0}", value);
        }

        catch (OverflowException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
Output: 
The Byte value is : 0
Example 3:

Program for

OverflowException csharp 
// C# program to demonstrate the
// Decimal.ToByte(Decimal) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        try {

            // Declaring the decimal variable
            Decimal a = -98.45m;

            // using ToByte() method;
            byte value = Decimal.ToByte(a);

            // Display the byte value
            Console.WriteLine("The Byte value "+
                             "is : {0}", value);
        }

        catch (OverflowException e) 
        {
            Console.Write("Exception Thrown: ");
            Console.Write("{0}", e.GetType(), e.Message);
        }
    }
}
Output: 
Exception Thrown: System.OverflowException
