C# byte Keyword

In C#, byte is a keyword which is used to declare a variable that can store an unsigned value between 0 to 255. byte keyword is an alias of System.Byte.

It occupies 1 byte (8 bits) in the memory.

Syntax

It can store value between 0 to 255.

Example of byte keyword in C#

Here, we are declaring a byte variable num, initializing it with the value 120 and printing its value, type, and size of a byte type variable.

using System;
using System.Text;

namespace Test {
  class Program {
    static void Main(string[] args) {
      //byte variable declaration
      byte num = 120;

      //printing value
      Console.WriteLine("num: " + num);
      //printing type of variable
      Console.WriteLine("Type of num: " + num.GetType());
      //printing size of a bool 
      Console.WriteLine("Size of a byte variable: " + sizeof(byte));

      //hit ENTER to exit
      Console.ReadLine();
    }
  }
}

Output

num: 120
Type of num: System.Byte
Size of a byte variable: 1
