/configuration辅助类
语言切换操作类 检查方法入参有值则切换到指定的资源无值则读取配置文件中的值若配置文件中仍无值则获取当前线程运行的语言环境切换到与语言环境相匹配的资源如果没有找到与之匹配的资源则不做操作。 切换资源之后将配置文件中的 language 的 value 改为当前所选的语言保存并刷新配置文件直到下次更改。 重写 Application 类的 OnStartup 方法在 OnStartup 中调用 SetLanguage 方法以实现应用程序启动对语言环境的判别。 /// summary

}资源 binding 解析类 ComBox 控件通常是通过 ItemSource 进行绑定默认情况下是无法对绑定的资源进行翻译的。 通过继承 MarkupExtension 类 重写 ProvideValue 方法来实现item 绑定 资源的 Key 的解析。 /// summary
