windows - #UWP 获取系统主题(Light/Dark)

Question

如何在UWP中获取windows系统主题？浅色/深色

var DefaultTheme = new Windows.UI.ViewManagement.UISettings();
WindowsThemeText.Text =DefaultTheme.UIElementColor(Windows.UI.ViewManagement.UIElementType.PageBackground).ToString();

我已经试过了，但它没有显示主题....

uiTheme 将根据系统 ui 主题只返回两种颜色 #FF000000(Dark) 或 #FFFFFFFF (Light)，所以你可以这样做。您可以为您的某些 ui 元素填充深色或浅色以显示当前系统主题

var DefaultTheme = new Windows.UI.ViewManagement.UISettings();
var uiTheme = DefaultTheme.GetColorValue(Windows.UI.ViewManagement.UIColorType.Background).ToString();
if(uiTheme == "#FF000000")
{
    WindowsThemeText.Text = "Dark";
}
else if(uiTheme == "#FFFFFFFF")
{
    WindowsThemeText.Text = "Light";
}
/*
else
{
    WindowsThemeText.Text = "Some new Updated theme found";
}
*/
