c# - 如何加载外部 XAML ResourceDictionary

Question

如何像这样动态添加 ResourceDictionary？

ResourceDictionary template = new ResourceDictionary();
template.Source = new Uri("Design.xaml", UriKind.Relative);
Application.Current.Resources.MergedDictionaries.Add(template);

对于绝对 Uri，它可以完美地工作，但对于 Relative 则不能。

我使用 XamlReader 类来执行此操作:

string exeFilePath = System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase;
string exeDirPath = Path.GetDirectoryName(exeFilePath);
string targetFile = "subfolder\\dictionary.xaml";
string path_to_xaml_dictionary = new Uri(Path.Combine(exeDirPath, targetFile)).LocalPath;
string strXaml = File.ReadAllText(path_to_xaml_dictionary);                    
ResourceDictionary resourceDictionary = (ResourceDictionary)XamlReader.Parse(strXaml);
Application.Current.Resources.MergedDictionaries.Add(resourceDictionary);

对我来说效果很好。
