SystemThemeManager Class

[m0lDaViA]

@pomianowski As i was looking at your ThemeManager classes so i can use them i was wondering if it is even necessary to check for themes at all except for the hc ones?
You are already using the SystemUsesLightThem reg key and to check if the value is 0 or 1.
Isn't it better and way easier to check only that instead of all themes ect?
What do you think?

Here an example:

private static SystemTheme GetCurrentSystemTheme()
 {
     var currentTheme =
         Registry.GetValue(
             @"HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes",
             "CurrentTheme",
             "aero.theme"
         ) as string
         ?? string.Empty;

     var appsUseLightTheme = Registry.GetValue(
         @"HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize",
         "AppsUseLightTheme",
         1
     );

     var systemUsesLightTheme =
         Registry.GetValue(
             @"HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize",
             "SystemUsesLightTheme",
             1
         ) ?? 1;

     if (!string.IsNullOrEmpty(currentTheme))
     {
         currentTheme = currentTheme.ToLower().Trim();

         if (currentTheme.Contains("hcblack.theme"))
         {
             return SystemTheme.HCBlack;
         }

         if (currentTheme.Contains("hcwhite.theme"))
         {
             return SystemTheme.HCWhite;
         }

         if (currentTheme.Contains("hc1.theme"))
         {
             return SystemTheme.HC1;
         }

         if (currentTheme.Contains("hc2.theme"))
         {
             return SystemTheme.HC2;
         }
     }

     if (appsUseLightTheme is 0 || systemUsesLightTheme is 0)
     {
         return SystemTheme.Dark;
     }

     return SystemTheme.Light;
 }````
