WPF 应用程序本地化-资源文件方式

WPF 应用程序需要本地化处理的时候，有多种方法，这里只对原始的方式即资源文件方式实现本地化作为简单介绍，加强学习和备忘，其他方法原理类似。

1.要实现本地化，首先添加资源文件,在资源文件中添加需要实现本地化的字段（这些繁琐的活可以交给GitHub Copilot 或其他AI辅助工具干）
省下来的时间认真检查以下或者前期好好规划以下UI显示元素的命名规则和标准，不要中英文混写，拼音英文混写，或者一会拼音一会英文。

2.本地化应用

  ResourceManager rm=new ResourceManager("WpfApp4.Resources.Strings",Assembly.GetExecutingAssembly()); //实例化资源读取对象，读取资源内容
  CultureInfo culture=new CultureInfo("en-US");//根据名称指定区域性初始化实例的显示内容，如果不指定，默认当前操作系统设置的区域语言
  System.Threading.Thread.CurrentThread.CurrentUICulture=culture; //获取或设置当前资源管理器使用当前区域性以便在运行时查找区域性特定的资源（即资源文件和其对应的属性）

3.通过MVVM方式对UI显示元素进行绑定，以便便于处理，当然也可以通过其他方式，可能比较费事

如：this.Title=rm.GetString("MainWindowTitle",CultureInfo.CultureUICulture)

下面以具体示例做说明：
