目录结构：
前台xaml调用方法：
<Window.Resources> <ResourceDictionary Source="Resource/Dictionary1.xaml"/> </Window.Resources>
后台代码调用方法：
ResourceDictionary resource = new ResourceDictionary(); resource.Source = new Uri(@"/WpfApp3;Component/resource/Dictionary2.xaml", UriKind.Relative); this.Resources = resource;
前后台使用ResourceDictionary 调用Resource
