如何检测 Windows 10 亮/暗模式? [英] How can I detect Windows 10 light/dark mode?

问题描述

我正在使用 Windows.UI.ViewManagement.UISettings 来获取系统强调色，但该类似乎没有任何用于亮/暗模式的方法或属性.我找不到有关此功能的文档，如何检测?

I'm using Windows.UI.ViewManagement.UISettings to get system accent color but it seems this class does not have any method or property for light/dark mode. I failed to find a document for this feature, how can I detect this?

PS:我正在制作一个无法访问 Windows.UI.Xaml 命名空间的 JS 应用.

PS: I'm making a JS app which does not have access for Windows.UI.Xaml namespace.

推荐答案

我找到了一个更简单的解决方案，它也适用于 JavaScript 应用程序，无需 Windows 运行时组件 - UISettings 类:

I have found an easier solution, which should work in JavaScript apps as well, without requiring the Windows Runtime Component - the UISettings class:

var uiSettings = new Windows.UI.ViewManagement.UISettings();
var color = uiSettings.getColorValue(
                        Windows.UI.ViewManagement.UIColorType.background
                       );

深色主题的黑色或浅色主题的白色颜色.

该类还有非常有用的事件 ColorValuesChanged，您可以使用它在运行时观察主题变化.

The class also has very useful event ColorValuesChanged which you can use to observe theme changes at runtime.
