1：监视所有控件的鼠标操作，键盘操作
鼠标按下，鼠标双击，键盘按下
2：注册消息处理函数
private const int WM_KEYDOWN = 0x0100;private const int WM_LBUTTONDOWN = 0x0201;
private const int WM_LBUTTONDBLCLK = 0x0203;
void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
(PresentationSource.FromVisual(this) as HwndSource).AddHook(new HwndSourceHook(WndProc));
}
IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
{
switch (msg)
{
case WM_KEYDOWN:
case WM_LBUTTONDOWN:
case WM_LBUTTONDBLCLK:
break;
}
return hwnd;
}
