C# 怎么拦截WIN+D 和 显示桌面的消息 最好有具体代码
使用钩子的方式拦截，这里有个问题是我拦截不到WIN+D 这组快捷键？？？？？有米谁知道怎么拦截？？？？还有显示桌面的那个按钮执行怎么拦截？？？？

 public void Hook_Start()
        {
            // 安装键盘钩子 
            if (hHook == 0)
            {
                KeyBoardHookProcedure = new HookProc(KeyBoardHookProc);

                Process[] process = System.Diagnostics.Process.GetProcesses();


                hHook = SetWindowsHookEx(WH_KEYBOARD_LL, KeyBoardHookProcedure, GetModuleHandle(Process.GetCurrentProcess().MainModule.ModuleName), 0);
                
                //如果设置钩子失败. 
                if (hHook == 0)
                {
                    Hook_Clear();
                    //throw new Exception("设置Hook失败!"); 
                }
            }
        }

public int KeyBoardHookProc(int nCode, IntPtr wParam, IntPtr lParam)
        {
            if (nCode >= 0)
            {
                KeyBoardHookStruct kbh = (KeyBoardHookStruct)Marshal.PtrToStructure(lParam, typeof(KeyBoardHookStruct));
}
}
------最佳解决方案--------------------
 KeyPress != null))
            {

                KeyboardHookStruct keyboardHookStruct =
                    (KeyboardHookStruct)Marshal.PtrToStructure(lParam, typeof(KeyboardHookStruct));

                // Is Control being held down?
                bool control = ((GetKeyState(VK_LCONTROL) & 0x80) != 0) 
------其他解决方案--------------------
参考一下，可以用KeyDown或 KeyUp 来判断是否按下了Win+D

protected override int HookCallbackProcedure(int nCode, int wParam, IntPtr lParam)
