这里以英语为默认语言，新建一个 Resource Dictionary (WPF)文件，并命名为DefaultLanguage.xaml,内容如下：
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib"><!--这行新增加的-->
<sys:String x:Key="OK">
</sys:String>
<sys:String x:Key="Cancel">
Cancel
</sys:String>
</ResourceDictionary>
默认语言文件的 BuildAction要设置为 Page，如图：
为了便于管理，一般将所有的语言文件都放在一个目录下，这里创建lang目录，
然后在创建另一个语言文件，这里是中文，命名为 zh_CN.xaml，内容如下：
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib">
<sys:String x:Key="OK">
</sys:String>
<sys:String x:Key="Cancel">
</sys:String>
</ResourceDictionary>
其他非默认语言的设置应该如下：
BuildAction设置为：Content ；CopyToOutputDirectory设置为：Copy if newer (先这样做吧，原因未清)
3.在App.xaml中配置默认语言：
<Application x:Class="LanTest.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary><!--这个节点就是配置默认语言的-->
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="lang\DefaultLanguage.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
4.实际使用(敲代码了)
4.1. 界面效果如下：
4.2. 界面的.xaml代码
1 <Window x:Class="LanTest.MainWindow"
2 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
3 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
4 Title="MainWindow" Height="350" Width="525">
5 <Grid>
6 <!--这里的{DynamicResource OK}就是动态调用 资源中的key为OK的内容-->
7 <Button Content="{DynamicResource OK}" HorizontalAlignment="Left" Margin="134,161,0,0" VerticalAlignment="Top" Width="104" Height="38"/>
8 <Button Content="{DynamicResource Cancel}" HorizontalAlignment="Left" Margin="278,161,0,0" VerticalAlignment="Top" Width="100" Height="38"/>
9 <Button Content="Button" HorizontalAlignment="Left" Margin="287,59,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click" Loaded="Button_Loaded"/>
10 <ComboBox Name="cbLang" HorizontalAlignment="Left" Margin="118,59,0,0" VerticalAlignment="Top" Width="120">
11 </ComboBox>
13 </Grid>
14 </Window>
