I have a wpf application that is designed for a 1900x1200 resolution but some of our users have used the windows display settings to resize everything by 125%-150%, is there a way to have an application ignore those settings and still display normally?

I have seen something called SetProcessDPIAware here, but havent had any luck with it.

Here is a screen shot of the application with the display scaling turned up to 150% Application with Scaling

As you can see the application is way too small and there is no way to get it to be correctly sized.

在这种情况下，Dpi 意识将无济于事。它只会改变 CompositionTarget.TransformToDevice 矩阵，但控件大小不会改变。

我使用视图框来缩放所有内容。我的应用程序中的所有尺寸都是为 Surface Pro 3 纵向设计的：

<Window>
    <Viewbox Stretch="Uniform">
        <Grid Width="1440" Height="2160">
            <!-- ... -->
        </Grid>
    </Viewbox>
</Window>

您可以根据屏幕 DPI 计算视图框大小。看到这个答案：https ://stackoverflow.com/a/12414433/991267

忽略 dpi 的新方法是：

右键单击您的项目

添加 > 新项目

找到“应用程序清单文件（仅限 Windows）

在第 55 行取消注释，或找到 dpiAware

  <application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings>
      <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>
      <longPathAware xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">true</longPathAware>
    </windowsSettings>
  </application>
