解决c#中全局热键处理的最佳方法？

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

public const int WM_HOTKEY = 0x0312;

[DllImport("user32.dll", SetLastError = true)]
public static extern bool RegisterHotKey(IntPtr hWnd, int id, uint fsModifiers, uint vk);

[DllImport("user32.dll", SetLastError = true)]
public static extern bool UnregisterHotKey(IntPtr hWnd, int id);

private static int hotkeyId = 0;

private void Form1_Load(object sender, EventArgs e)
{
    RegisterHotKey(this.Handle, hotkeyId, (uint)Keys.ControlKey, (uint)Keys.D1);
}

protected override void WndProc(ref Message m)
{
    if (m.Msg == WM_HOTKEY)
    {
        switch (m.WParam.ToInt32())
        {
            case hotkeyId:
                MessageBox.Show("热键已被触发！");
                break;
        }
    }
    base.WndProc(ref m);
}
