Comment rendre les styles de ressources WPF commutables à l'exécution?

J'ai le style des ressources en WPF travail, de sorte que dans mon Application.xaml je peux définir si le client ou l'administrateur de mise en page est utilisé. Cela fonctionne très bien par arriver tout le style de la principale XAML en HTML/CSS-comme la mode.

Maintenant, comment puis-je faire de cette dynamique afin que je puisse cliquer sur un bouton dans mon application et changer la mise en page entre le client et l'administrateur au moment de l'exécution?

Addendum:

Grâce Meeh pour les liens, j'ai donc fait ça et quand je debug, il suit à travers toutes les lignes, mais ne change toujours pas la mise en pagede quoi dois-je faire, de sorte que les modifications de mise en page au moment de l'exécution?

private void Button_Switch_Layout_Click(object sender, RoutedEventArgs e)
{
    string layoutIdCode = "administrator";

    switch (layoutIdCode)
    {
        case "administrator":
            langDictPath = "Resources/AdministratorLayout.xaml";
            break;

        case "customer":
            langDictPath = "Resources/CustomerLayout.xaml";
            break;
    }

    Uri langDictUri = new Uri(langDictPath, UriKind.Relative);
    ResourceDictionary langDict = Application.LoadComponent(langDictUri) as ResourceDictionary;
    Application.Current.Resources.MergedDictionaries.Clear();
    Application.Current.Resources.MergedDictionaries.Add(langDict);
}
