更改ResourceDictionary不会明显影响WPF中的窗口

简单的答案是,您需要清除应用程序合并的资源字典。这里有一些代码让你开始

ResourceDictionary dictionary = GetThemeResourceDictionary(yourTheme) 

if (dictionary != null)
{
     App.Current.Resources.MergedDictionaries.Clear();
     App.Current.Resources.MergedDictionaries.Add(dictionary);
}

public ResourceDictionary GetThemeResourceDictionary(string theme)
{
    if (theme != null)
    {
        Assembly assembly = Assembly.LoadFrom("WPF.Themes.dll");
        string packUri = String.Format(YourThemeFolder/{0}.xaml", theme);
        return Application.LoadComponent(new Uri(packUri, UriKind.Relative)) as ResourceDictionary;
    }
    return null;
}

WPF themes . 它引入了一个主题管理器类和一组内置的主题,这真是难以置信。如果在安装或添加新主题时遇到任何困难,请与我联系:)
