推荐答案

参见Form.FormClosing事件 [ ^ ]

检查FormClosingEventArgs的CloseReason属性，如果是CloseReason.WindowsShutDown然后将e.Cancel设置为True则应该阻止表单立即关闭。

然后，你可以使用

See the Form.FormClosing event[^]
Check the CloseReason property of the FormClosingEventArgs, if it is CloseReason.WindowsShutDown then set e.Cancel to True then it should prevent the form closing immediately.
Then, you can stop shutdown by using

Process.Start("shutdown", "-a")

我没有在Win8或Win10中试过这个，但是它应该仍然有用。

I haven't tried this in Win8 or Win10, but it should still work.
