1、使用资源字典，首先新建两个字典文件en-us.xaml、zh-cn.xaml。定义中英文的字符串在这里面【注意：添加xmlns:s="clr-namespace:System;assembly=mscorlib】
zh-cn.xam如下：
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:s="clr-namespace:System;assembly=mscorlib" xmlns:local="clr-namespace:WpfApplication"> <s:String x:Key="buttonNewTaskWindow">新建任务</s:String> <s:String x:Key="buttonProperty">任务属性</s:String> < /ResourceDictionary>
en-us.xaml如下：
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:s="clr-namespace:System;assembly=mscorlib" xmlns:local="clr-namespace:WpfApplication"> <s:String x:Key="buttonNewTaskWindow">New Task</s:String> <s:String x:Key="buttonProperty">Task Property</s:String> </ResourceDictionary>
2、讲两个资源字典添加到App.xaml中，这里注意下，因为两个字典中有同样字符，如果没有动态更改，默认后添加的生效
App.xaml如下：
<Application x:Class="WpfApplication.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> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Resources\en-us.xaml"/> <ResourceDictionary Source="Resources\zh-cn.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> < /Application>
3、在界面设计器中需要显示的位置添加动态资源
例如：
<Button x:Name="buttonNewTaskWindow" Content="{DynamicResource buttonNewTaskWindow}"/> <Button x:Name="buttonProperty" Content="{DynamicResource buttonProperty}"/>
4、动态切换，重新加载资源文件
代码如下：
List<ResourceDictionary> dictionaryList = new List<ResourceDictionary>(); foreach (ResourceDictionary dictionary in Application.Current.Resources.MergedDictionaries) { dictionaryList.Add(dictionary); } string requestedCulture = @"Resources\en-us.xaml"; ResourceDictionary resourceDictionary = dictionaryList.FirstOrDefault(d => d.Source.OriginalString.Equals(requestedCulture)); Application.Current.Resources.MergedDictionaries.Remove(resourceDictionary); Application.Current.Resources.MergedDictionaries.Add(resourceDictionary);
5、执行以上代码，即可完成切换
