How to find the size of a class in C#

Question

public class A
{
  int x;
  float y;
}

How to find the size of the class in C#. Is there any operator like Sizeof(), which used to be in C++

Answer 1

The following would give you the size of the C# class:

Marshal.SizeOf(typeof(Myclass));

using System.Runtime.InteropServices;

[StructLayout(LayoutKind.Sequential)]
class Myclass
{

}

Remember size of a class depends on padding.
