How to use sizeof() operator to find the size of a data type or a variable in C#

CsharpProgrammingServer Side Programming

The sizeof() datatype returns the size of a data type. Let’s say you need to find the size of int datatype −

sizeof(int);

For double datatype

sizeof(double);

Let us see the complete example to find the size of various datatypes −

Example

 Live Demo

using System;

namespace Demo {

   class Program {

      static void Main(string[] args) {

         Console.WriteLine("The size of int is {0}", sizeof(int));
         Console.WriteLine("The size of int is {0}", sizeof(char));
         Console.WriteLine("The size of short is {0}", sizeof(short));
         Console.WriteLine("The size of long is {0}", sizeof(long));
         Console.WriteLine("The size of double is {0}", sizeof(double));

         Console.ReadLine();
      }
   }
}

Output

The size of int is 4
The size of int is 2
The size of short is 2
The size of long is 8
The size of double is 8
