How to convert class/struct to a byte array

With this class you can easy convert your class/struct to a byte array.
Very useful when using the socket.

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

class CommonConvertion
{
public static byte[] StructureToByteArray(object obj)
{
int Length = Marshal.SizeOf(obj);
byte[] bytearray = new byte[Length];
IntPtr ptr = Marshal.AllocHGlobal(Length);
Marshal.StructureToPtr(obj, ptr, false);
Marshal.Copy(ptr, bytearray, 0, Length);
Marshal.FreeHGlobal(ptr);
return bytearray;
}

public static void ByteArrayToStructure(byte[] bytearray, ref object obj)
{
int Length = Marshal.SizeOf(obj);
IntPtr ptr = Marshal.AllocHGlobal(Length);
Marshal.Copy(bytearray, 0, ptr, Length);
obj = Marshal.PtrToStructure(ptr, obj.GetType());
Marshal.FreeHGlobal(ptr);
}
}

Have fun.
