问题描述

OK，我知道有关于这个主题相当多的职位。然而，他们没有提供解决我的问题：我不想只是关闭我的显示器上，我希望我的代码以关闭特定显示器。大多数人指的是URL，的 http://fci-h.blogspot.com/2007/03/turn-off-your-monitor-via-code-c.html ，不帮助这里，因为它会关闭所有的显示器。

OK, I know there are quite a few posts on this topic. However, none of them provide the solution to my issue: I don't want just to turn off my monitor(s), I wish my code to turn off a specific monitor. The URL the most people refer to, http://fci-h.blogspot.com/2007/03/turn-off-your-monitor-via-code-c.html, doesn't help here, as it turns off all the displays.

所以，我有我的笔记本电脑的屏幕和一个额外的外部显示器。虽然我看电影，我切换显示到外接显示器和我的笔记本电脑屏幕变黑，但是，它仍然是上，并在黑暗中发光。我想将其关闭。谁能帮助吗？

So, I have my laptop screen and an additional external monitor. While I'm watching movies, I switch the display to the external monitor and my laptop screen goes black, however, it's still on and glowing in the dark. I wish to turn it off. Could anyone help please?

编辑：有什么办法来acomplish这一点，这意味着它不需要有在.net中写入。基本上，我只是需要一个.exe文件，该文件能够把特定的显示器关闭，并在交替进行。

Is there any way to acomplish this, meaning it needn't have to be written in .Net. Basically, I just need an .exe file that's able to turn the particular monitor off and on alternately.
