有没有办法来触发窗​​口壁纸幻灯片洗牌？ preferably东西，我可以从.NET

Is there a way to trigger a shuffle in windows wallpaper slideshow? Preferably something I can use from .net

编辑：所以我想用IActiveDesktop接口，我从的此处，我试图用这样的：

so I'm trying to use the IActiveDesktop interface, I got it from here, I tried to use it like this:

public static IActiveDesktop GetActiveDesktop()
{
    Type typeActiveDesktop = Type.GetTypeFromCLSID(new Guid("{75048700-EF1F-11D0-9888-006097DEACF9}"));
    return (IActiveDesktop) Activator.CreateInstance(typeActiveDesktop);
}

，然后调用它是这样的：

and then calling it like this:

IActiveDesktop dt = GetActiveDesktop();
dt.ApplyChanges(AD_APPLY.ALL | AD_APPLY.FORCE | AD_APPLY.BUFFERED_REFRESH);
