WPF后台代码调用资源字典

WPF后台代码调用资源字典

        public static Style GetResource(string uri, string key)
        {
            foreach (ResourceDictionary rd in Application.Current.Resources.MergedDictionaries)
            {
                if (rd.Source == new Uri(uri, UriKind.RelativeOrAbsolute))
                    return rd[key] as Style;
            }
            return null;
        }

引用代码：

    rb.Style = ResourceHelper.GetResource("Resources/ButtonStyle.xaml", "btnStyle1");

 注意要在app.xaml的<ResourceDictionary.MergedDictionaries>中声明。
