Programmatically change Windows power settings
提问by Petrus Theron
Is it possible to change the power-saving behaviour of a laptop computer on lid close from hibernate/standby/shutdownto Do Nothingfrom the .NET Framework?
是否可以将笔记本电脑在关闭盖子时的节能行为从休眠/待机/关机更改为从 .NET Framework不执行任何操作？
Edit:it would appear that by setting the value to Standby and blocking the standby from my application, the lid close event can be detected, which is what I'm really after.
编辑：似乎通过将值设置为 Standby 并阻止我的应用程序中的待机，可以检测到盖子关闭事件，这就是我真正想要的。
I found this questionwhich deals with detecting lid close, but it boils down to using a standby event or writing a driver.
我发现这个问题涉及检测盖子关闭，但归结为使用待机事件或编写驱动程序。

Yes, you can use the WMI classes.
是的，您可以使用 WMI 类。
Take a look hereto an introduction to WMI
看这里对 WMI 的介绍
Note that you can also use Application.SetSuspendState, but this method only allows you to suspend or hibernate. So I guess it doesn't match your needs...
请注意，您也可以使用Application.SetSuspendState，但此方法仅允许您暂停或休眠。所以我想它不符合您的需求......
About the lid, there seems to be a wayto detect if the lid is closed or not...
关于盖子，似乎有一种方法可以检测盖子是否关闭......
