如何在 WinUI 3 应用程序中监视系统颜色变化

Question

If I have a WinUI 3 application that is executing, and I change the Color setting from Light to Dark in the Settings/Personalization/Colors dialog, how can I detect this change in the WinUI 3 application?

Answer 1

After rephrasing my question to UWP from WinUI 3, a satisfactory answer resulted. The UISettings class provides the solution.

UISettings uiSettings = new UISettings();

uiSettings.ColorValuesChanged += ColorValuesChanged;

private void ColorValuesChanged(UISettings sender, object args) { var accentColor = sender.GetColorValue(UIColorType.Accent);

  var backgroundColor = sender.GetColorValue(UIColorType.Background);

}

Thanks to Martin Zikmund for this solution:
