1、新建两个资源字典文件zh-CN.xaml和en-US.xaml，分别存储中文模板和英文模板
(1) zh-CN.xaml
<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="labelLanguage">语言:</sys:String>
<sys:String x:Key="comboEnglish">英语</sys:String>
<sys:String x:Key="comboChinese">中文</sys:String>
<sys:String x:Key="BtnContent">确定</sys:String>
<sys:String x:Key="textboxContent">这是语言切换测试文本内容</sys:String>
</ResourceDictionary>(2) en-US.xaml
<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="labelLanguage">Language:</sys:String>
<sys:String x:Key="comboEnglish">English</sys:String>
<sys:String x:Key="comboChinese">Chinese</sys:String>
<sys:String x:Key="BtnContent">OK</sys:String>
<sys:String x:Key="textboxContent">This is the language switching test text content.</sys:String>
</ResourceDictionary>
2、在App.xaml文件内，引入默认使用的语言对应的资源字典，在此默认语言为中文
<Application x:Class="LanguageChangeDemo.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:LanguageChangeDemo"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="zh-CN.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
3、在MainWindow.xaml中添加中英文单选按钮和切换按钮，以及测试文本；并使用{DynamicResource x:Key}动态引用资源字典
<Window x:Class="LanguageChangeDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:LanguageChangeDemo"
mc:Ignorable="d"
Title="{DynamicResource International}" Height="250" Width="395" WindowStartupLocation="CenterScreen">
<Grid>
<Label Content="{DynamicResource labelLanguage}" HorizontalAlignment="Left" Margin="34,54,0,0" VerticalAlignment="Top" HorizontalContentAlignment="Center" VerticalContentAlignment="Center"/>
<RadioButton x:Name="cn" Content="{DynamicResource comboChinese}" GroupName="LanguangeChoice" HorizontalAlignment="Left" Margin="106,60,0,0" VerticalAlignment="Top" HorizontalContentAlignment="Left" VerticalContentAlignment="Center" Checked="RadioButton_Checked" IsChecked="True"/>
<RadioButton x:Name="en" Content="{DynamicResource comboEnglish}" GroupName="LanguangeChoice" HorizontalAlignment="Left" Margin="198,60,0,0" VerticalAlignment="Top" HorizontalContentAlignment="Left" VerticalContentAlignment="Center" Checked="RadioButton_Checked"/>
<Button Visibility="Hidden" Content="{DynamicResource BtnContent}" HorizontalAlignment="Left" Margin="274,54,0,0" VerticalAlignment="Top" Height="25" Width="60" Click="Button_Click"/>
<TextBox Text="{DynamicResource textboxContent}" HorizontalAlignment="Center" Margin="0,132,0,0" TextWrapping="Wrap" VerticalAlignment="Top" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Width="395" BorderThickness="0"/>
</Grid>
</Window>4、MainWindow.xaml.cs中添加切换逻辑
namespace LanguageChangeDemo
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
string selectItem = "";
string languageType = "";
public MainWindow()
{
InitializeComponent();
}
private void RadioButton_Checked(object sender, RoutedEventArgs e)
{
RadioButton radioButton = sender as RadioButton;
if (radioButton.IsChecked == true)
{
selectItem = radioButton.Content.ToString();
switch (selectItem)
{
case "中文":
languageType = "zh-CN";
Change();
break;
case "英语":
languageType = "en-US";
Change();
break;
case "Chinese":
languageType = "zh-CN";
Change();
break;
case "English":
languageType = "en-US";
Change();
break;
default:
break;
}
}
}
private void Button_Click(object sender, RoutedEventArgs e)
{
改版前
//if (languageType != null)
//{
// ResourceDictionary langRd = null;
// try
// {
// //根据名字载入语言文件
// langRd = Application.LoadComponent(new Uri(languageType + ".xaml", UriKind.Relative)) as ResourceDictionary;
// }
// catch (Exception e2)
// {
// MessageBox.Show(e2.Message);
// }
// if (langRd != null)
// {
// //如果已使用其他语言,先清空
// if (this.Resources.MergedDictionaries.Count > 0)
// {
// this.Resources.MergedDictionaries.Clear();
// }
// this.Resources.MergedDictionaries.Add(langRd);
// }
//}
}
public void Change()
{
if (languageType != null)
{
ResourceDictionary langRd = null;
try
{
//根据名字载入语言文件
langRd = Application.LoadComponent(new Uri(languageType + ".xaml", UriKind.Relative)) as ResourceDictionary;
}
catch (Exception e2)
{
MessageBox.Show(e2.Message);
}
if (langRd != null)
{
//如果已使用其他语言,先清空
if (this.Resources.MergedDictionaries.Count > 0)
{
this.Resources.MergedDictionaries.Clear();
}
this.Resources.MergedDictionaries.Add(langRd);
}
}
}
}
}5、效果
