Windows Phone 7检测当前主题

Add this code to your App.xaml.cs inside your App class to enable a static property that will give you the current theme at runtime.

// An enum to specify the theme.
public enum AppTheme
{
    Dark = 0,
    Light = 1
}
 
// Detecting the current theme.
private static Color lightThemeBackground = Color.FromArgb(255, 255, 255, 255);
private static Color darkThemeBackground = Color.FromArgb(255, 0, 0, 0);
private static SolidColorBrush backgroundBrush;
internal static AppTheme CurrentTheme
{
    get
    {
        if ( backgroundBrush == null )
            backgroundBrush = Application.Current.Resources["PhoneBackgroundBrush"] as SolidColorBrush;
 
        if (backgroundBrush.Color == lightThemeBackground)
            return AppTheme.Light;
        else if (backgroundBrush.Color == darkThemeBackground)
            return AppTheme.Dark;
 
        return AppTheme.Dark;
    }
}
