Question

有人知道Powershell代码如何旋转屏幕。我已经使用了$ width和$ height参数，但是还有旋转参数吗？

我已经在以下网站上进行搜索：

我已经使用了以下代码：

Function Set-ScreenResolution { 
param ( 
[Parameter(Mandatory=$true, 
  Position = 0)] 
[int] 
$Width, 
[Parameter(Mandatory=$true, 
  Position = 1)] 
[int] 
$Height
) 
$pinvokeCode = @"

它看起来像this is possible with the Win32 API（C/C++个库）。通过一些内联C＃编译，您可以像使用其他.NET语言一样，从Powershell P/Invoke进入Win32 API。

我在上面链接到一个Github脚本，我发现该脚本使用上述Win32 API从Powershell更改了屏幕方向。如果您想进一步了解P/Invoke本身，请参阅此处的official Microsoft Documentation。
