修炼九阴真经Windows Phone开发 (7)：本地化应用程序栏Localizing an Application Bar 下

本节介绍另一个本地化的方法：

在项目中添加资源文件：（这个文件将包含应用程序的默认语言的资源）

将要名称和值添加进去。（作为应用程序中向用户显示字符串值）.

重复上面的方法，向项目中添加更多的其它语言资源文件。（参见后面的截图）

 

定义默认的区域

1.在解决方案资源管理器中，右键单击项目名称，选择属性，在application选项卡中，点 程序集信息。在非特定语言列表中，选择默认区域性。此标识语言的默认资源文件

中的字符串。例如，如果默认资源文件被命名为AppResources.resx，并在该文件中的字符串支持英语，则可以选择english作为项目的中立国语言。

 

添加LocalizedStrings类处理资源文件：

    public class LocalizedStrings
    {
        public LocalizedStrings()
        {
        }

        private static ApplicationBarSample.AppResources localizedresources = new ApplicationBarSample.AppResources();

        public ApplicationBarSample.AppResources Localizedresources { get { return localizedresources; } }

    }
