The trouble I'm having is with using...
我遇到的麻烦就是使用......
[DllImport("user32")]
public static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);
...and then...
SendMessage(???, WM_SYSCOMMAND, (IntPtr)SC_MONITORPOWER, (IntPtr)MONITOR_OFF);
SendMessage wants the Form's Handle but I'm not using Forms so cannot get the Handle.
SendMessage想要Form的Handle,但我没有使用Forms,所以无法获得Handle。
Is there any other way I can put the monitor to sleep OR get the Handle in WPF?
有没有其他方法可以让显示器进入睡眠状态或获取WPF中的句柄?

Or use
HwndSource source = (HwndSource)HwndSource.FromVisual(this);
source.Handle...
to get a handle from a single element in the form, also runs for the whole window.
从表单中的单个元素获取句柄,也运行整个窗口。
