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

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);    } }
