导致表单问题的监视器大小差异：Powershell 与 ISE

Question

我在 Powershell 中设计了以下表单的变体。但是，当我使用 ISE 运行它时，它会在与 Powershell 控制台不同的 size/resolution 中弹出。我一直试图通过动态调整不同字体和控件的 height/width 来对此进行控制，但即使其他一切都调整正确，[system.Windows.Forms.Label] 控件的字体也不会调整与其他一切。

经调查，应用程序似乎选择了不同分辨率的主屏幕，尽管两者的辅助屏幕是一致的。为什么这两个应用程序会检测到不同的主屏幕分辨率？

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Screen]::PrimaryScreen

Powershell 输出：

BitsPerPixel : 32
Bounds       : {X=0,Y=0,Width=1368,Height=912}
DeviceName   : \.\DISPLAY1
Primary      : True
WorkingArea  : {X=0,Y=0,Width=1368,Height=882}

ISE 输出：

BitsPerPixel : 32
Bounds       : {X=0,Y=0,Width=2736,Height=1824}
DeviceName   : \.\DISPLAY1
Primary      : True
WorkingArea  : {X=0,Y=0,Width=2736,Height=1764}

Answer 1

我仍然不完全确定为什么检测到的主显示器分辨率在 ISE/Powershell 之间会有所不同，但我找到了变异行为的来源：

由于主监视器的分辨率极高，它有一个额外的缩放参数 200%。所以 ISE 似乎检测到 'true' 分辨率为 2736x1824，其中 Powershell 检测到伪分辨率为 1368x912，但没有检测到它运行时用于填充显示器的 200% 缩放比例。

虽然我无法像我希望的那样正确检测或解释缩放比例，但我已经解决了 [system.Windows.Forms.Label] 的大小不一致问题，这是该行为的合适解决方法。一件令人惊讶的事情是 Label 字体大小是自动缩放的，所以当我从 $FontLabel 中删除手动缩放因子时，它会正确缩放，尽管它仍然需要 $FontText:

的缩放因子

$FontLabel = "Microsoft Sans Serif,$(11)"
$FontText  = "Microsoft Sans Serif,$(20*$w)"

因此 通过将我的缩放因子应用于除标签字体之外的所有内容，我能够使表单在两个应用程序中适当缩放。
