how to use RegisterHotKey() in C#?

Question

I'm trying register a hot key, I'm translating this C++ code,I wrote it:

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

namespace ConsoleApplication1
{
    class Program
    {
        [DllImport("user32.dll")]
        public static extern
            bool RegisterHotKey(IntPtr hWnd, int id, uint fsModifiers, int vk);
        [DllImport("user32")]
        public static extern
            bool GetMessage(ref Message lpMsg, IntPtr handle, uint mMsgFilterInMain, uint mMsgFilterMax);

        public const int MOD_ALT = 0x0001;
        public const int MOD_CONTROL = 0x0002;
        public const int MOD_SHIFT = 0x004;
        public const int MOD_NOREPEAT = 0x400;
        public const int WM_HOTKEY = 0x312;
        public const int DSIX = 0x36;

        static void Main(string[] args)
        {
            if (!RegisterHotKey(IntPtr.Zero, 1, MOD_ALT | MOD_NOREPEAT, DSIX))
            {
                Console.WriteLine("failed key register!");
            }

            Message msg = new Message();

            while (!GetMessage(ref msg, IntPtr.Zero, 0, 0))
            {
                if (msg.message == WM_HOTKEY)
                {
                    Console.WriteLine("do work..");
                }
            }

            Console.ReadLine();
        }
    }

    public class Message
    {
        public int message { get; set; }
    }
}

but it RegisterHotKey() ever returns false. I'm not sure about the arguments passed in method, IntPtr.Zero is for be to equivalent to null and message class to be object required in second argument. can someone clarify please? any help is very appreciated!

Basically, you have to create a "hidden" form to make it work
