Windows 7 用于更改屏幕方向的Powershell脚本
我写了一个脚本，将主屏幕方向更改为纵向。我的屏幕是1920X1200 它运行并且没有报告错误。但是屏幕没有像我预期的那样旋转 代码是根据设置屏幕分辨率（Andy Schneider）修改的。Windows 7 用于更改屏幕方向的Powershell脚本,windows-7,multiple-monitors,powershell,orientation,for-loop,Windows 7,Multiple Monitors,Powershell,Orientation,For Loop,我写了一个脚本，将主屏幕方向更改为纵向。我的屏幕是1920X1200 它运行并且没有报告错误。但是屏幕没有像我预期的那样旋转 代码是根据设置屏幕分辨率（Andy Schneider）修改的。 有人能帮我看一下吗 一些参考网站： 设置屏幕分辨率： C更改方向代码（MSDN）以编程方式更改屏幕方向： 我的代码： Function Set-ScreenOrientation { $pinvokeCode = @" using System; using System.Runtime.
