WPF 实际国际化多语言界面

         前段时候写了一个WPF多语言界面处理,个人感觉还行,分享给大家.使用合并字典,静态绑定,动态绑定.样式等东西

效果图

       定义一个实体类LanguageModel,实际INotifyPropertyChanged接口

 资料文件直接使用 XX.xaml文件    注:语言资源文件在VS2010的属性设置   复制到输出目录:始终复制     生成操作:内容   ,确保xaml文件会复制到项目中,而不是编译到dll中

 1 <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 2                     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 3                     xmlns:sys="clr-namespace:System;assembly=mscorlib">
 4     <sys:String x:Key="LanguageCode">zh</sys:String>
 5     <sys:String x:Key="LanguageName">简休中文</sys:String>
 6     <sys:String x:Key="LanguageDisplayName">简休中文</sys:String>
 7     <sys:String x:Key="LanguageEnabled">true</sys:String>

默认语言可以在App.xaml里设置

 1 <Application x:Class="WpfApplication1.App"
 2              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 3              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 4              Startup="Application_Startup"
 5              StartupUri="MainWindow.xaml">
 6     <Application.Resources>
 7         <ResourceDictionary>
 8             <ResourceDictionary.MergedDictionaries>
 9                 <ResourceDictionary Source="Resource/Language/zh.xaml"/>
10             </ResourceDictionary.MergedDictionaries>
11         </ResourceDictionary>
12     </Application.Resources>
13 </Application>

界面上使用动态绑定或静态绑定资源  (DynamicResource  ,StaticResource) ,  DataGrid表头使用HeaderSytle

      动态绑定:可以实时更新语言种类.

　　静态绑定,不能实时更新语言种类,如:在登录的时候已经确实语言种类,进入系统后而不能更改.

示例效果界面
