c# 想做全局快捷键 按网上教程来，做完没反应

Question

    代码如下，哪里写错了？？



            public void Frmain()
    {
        InitializeComponent();
        RegisterHotKey(this.Handle, 10, MODKEY.ALT, Keys.X);
        RegisterHotKey(this.Handle, 11, MODKEY.ALT, Keys.S);
    }
    protected override void WndProc(ref Message m)
    {
        if (m.Msg == 0x0312)
        {
            switch (m.WParam.ToInt32())
            {
                case 10:
                    MessageBox.Show("56456465");
                    break;
                case 11:
                    MessageBox.Show("adsadas");
                    break;
                default:
                    break;
            }
            return;
        }
        base.WndProc(ref m);
    }

    //要定义热键的窗口的句柄
    //定义热键ID（不能与其它ID重复）int id, 
    //标识热键是否在按Alt、Ctrl、Shift、Windows等键时才会生效KeyModifiers fsModifiers,                 Keys vk                     //定义热键的内容
    [DllImport("user32.dll")]
    public static extern bool RegisterHotKey(IntPtr wnd, int id, MODKEY mode, Keys vk);

    [DllImport("user32.dll")]
    public static extern bool UnregisterHotKey(IntPtr wnd, int id);

    [Flags()]
    public enum MODKEY
    {
        None = 0,
        ALT = 0x0001,
        CTRL = 0x0002,
        SHIFT = 0x0004,
        WIN = 0x0008,
    }

Answer 1

L = 0x0002,
SHIFT = 0x0004,
WIN = 0x0008,
}
