如何在 Windows Phone 设备上获取屏幕分辨率 [英] How to get screen resolutions on Windows Phone devices

问题描述

我遇到了问题，希望得到专家的帮助.我正在尝试获得屏幕分辨率，以便我可以根据手机类型使用适当的布局/图像.

I am running into issue and would appreciate expert’s help here. I am trying to get screen resolution so that I can use appropriate layouts/images based on phone types.

我的项目类型是 WP7.每当我在不同的 WP7 和 WP8 设备上运行代码时，我每次都获得相同的分辨率(800 X 480).预期的行为是我根据设备类型获得不同的分辨率，例如WVGA = 800 x 480，WXGA = 1280 x 768，720p = 1280 x 720.

My project type is WP7. Whenever I run code on different WP7 and WP8 devices, I get the same resolution everytime (800 X 480). Expected behavior is I get different resolution based on device type e.g. WVGA = 800 x 480, WXGA = 1280 x 768, 720p = 1280 x 720.

下面的所有 3 个代码片段都为我提供了相同的 800 X 480 分辨率，这不是预期的行为.

All the 3 code snippets below gave me same resolution of 800 X 480 which is not expected behavior.

Application.Current.RootVisual.RenderSize.Height + " x " + Application.Current.RootVisual.RenderSize.Width;

(App.Current.RootVisual as FrameworkElement).ActualHeight + " x " + (App.Current.RootVisual as FrameworkElement).ActualWidth;

App.Current.Host.Content.ActualHeight + " x " + App.Current.Host.Content.ActualWidth;

MSDN 文章讨论了如何在 WP8 中执行此操作，但请注意，我希望代码也能在 WP7 设备上运行.

The MSDN article talks about how to do this in WP8 but please note that I want code to run on WP7 device as well.

推荐答案

您可以尝试使用反射加载 App.Current.Host.Content.ScaleFactor.

You can try load App.Current.Host.Content.ScaleFactor using reflection.

我现在没有 wp8 环境，但是你可以看到类似的解决方案 此处.他们用它在 wp7.8 上创建王尔德瓷砖

I don't have my wp8 environment now, but you can see the similar solution here. They use it to create wilde tiles on wp7.8
