有没有办法避免使用Windows商店应用程序ResourceLoader使用硬编码的resw键？

有没有办法避免在Windows商店应用程序中使用resw文件中包含的全球化字符串使用硬编码键？ 即

// I have to use a hard-coded string key, which may violate the // DRY principle to gain access to the translation from C#: var translation = Windows.ApplicationModel.Resources.ResourceLoader.GetString("MyStringKey/Text")

您可以使用下面的T4模板自动生成resw文件周围的C＃包装器。 这意味着您无需使用魔术字符串资源键来丢弃代码来访问C＃中的翻译 – 然后您知道所有密钥在编译时都是有效的，而不是运行时。 该模板生成以下代码：

 internal static class Translation { public static ResourceLoader ResourceLoader { get; private set; } static Translation() { ResourceLoader = new ResourceLoader(); } public static string MyFirstString { get { return ResourceLoader.GetString("MyFirstString/Text"); } } } 

这是由以下T4模板生成的：
