How to find the size of a variable without using sizeof in C#?

CsharpProgrammingServer Side Programming

To get the size of a variable, sizeof is used.

int x;
x = sizeof(int);

To get the size of a variable, without using the sizeof, try the following code −

// without using sizeof
byte[] dataBytes = BitConverter.GetBytes(x);
int d = dataBytes.Length;

Here is the complete code.

Example

 Live Demo

using System;
class Demo {
   public static void Main() {
      int x;
      // using sizeof
      x = sizeof(int);
      Console.WriteLine(x);
      // without using sizeof
      byte[] dataBytes = BitConverter.GetBytes(x);
      int d = dataBytes.Length;
      Console.WriteLine(d);
   }
}
