【WPF】 热重载切换多语言

如何使用WPF热重载切换语言

一、依赖包

两个依赖包

1.Antelcat.I18N.WPF 网址：https://github.com/XAMLMarkupExtensions/WPFLocalizeExtension

2.WPFLocalizeExtension 网址：https://github.com/Antelcat/I18N?tab=readme-ov-file

 二、创建资源文件

ps：项目名字拼写有误——更正为MutilCultureDemo

1.创建Resrouces文件夹，新建资源文件.resx，这个资源浏览器必须是VS202217.10+以上的版本才有，没有就去更新IDE

2.使用先前的.Antelcat.I18N.WPF包动态生成资源键：

using Antelcat.I18N.Attributes;

namespace MultCultrueDemo.Resources;

[ResourceKeysOf(typeof(Lang))]
public partial class LangKeys
{ 
}

三、Xaml代码

1.引入两个依赖包的命名空间：

xmlns:lang="clr-namespace:MultCultrueDemo.Resources"
xmlns:lex="http://wpflocalizeextension.codeplex.com" 

lex:ResxLocalizationProvider.DefaultAssembly="MultCultrueDemo"
lex:ResxLocalizationProvider.DefaultDictionary="Lang" 

<Grid>
    <Grid.Resources>
        <Style BasedOn="{StaticResource {x:Type Button}}" TargetType="Button">
            <Setter Property="Width" Value="120" />
            <Setter Property="Height" Value="25" />
            <Setter Property="Margin" Value="5" />
        </Style>
    </Grid.Resources>
    <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
        <TextBlock FontSize="32" Text="{I18N {x:Static lang:LangKeys.MainWindow_WelcomeMessage}}" />
        <StackPanel
            Margin="0,16,0,0"
            HorizontalAlignment="Center"
            Orientation="Horizontal">
            <Button
                Width="80"
                Margin="0,0,5,0"
                Content="{I18N {x:Static lang:LangKeys.MainWindow_English_Button_Content}}"
                Tag="en" 
                Click="ChangeLanguage_Click"
                />
            <Button
                Width="80"
                Margin="5,0,0,0"
                Content="{I18N {x:Static lang:LangKeys.MainWindow_Chinese_Button_Content}}"
                Click="ChangeLanguage_Click"
                Tag="zh-CN" />

        </StackPanel>
        <Button
            Margin="0,16,0,0"
            HorizontalAlignment="Center"
            Content="{I18N {x:Static lang:LangKeys.MainWindow_ShowMessage_Button_Content}}" Click="Button_Click" />
    </StackPanel>
</Grid>

绑定语言源：<TextBlock Text="{I18N {x:Static myProject:LangKeys.Language}}"/>

四、后台代码

在xaml.cs中using MultCultrueDemo.Resources;

using System.Globalization;
using System.Windows;
using System.Windows.Controls;

 private void ChangeLanguage_Click(object sender, RoutedEventArgs e)
 {
     var culture = ((Button)sender).Tag.ToString(); // 接收xaml中Button的Tag属性值
     var cultureInfo = new CultureInfo(culture);
     Thread.CurrentThread.CurrentCulture = cultureInfo;
     Thread.CurrentThread.CurrentUICulture = cultureInfo;
　　　// 更改语言 —— I18NExtension.Culture = new CultureInfo("language code")
     I18NExtension.Culture = cultureInfo;
 }

 private void Button_Click(object sender, RoutedEventArgs e)
 {

     MessageBox.Show(Lang.MainWindow_ShowMessage_Button_Content, Lang.Message_Caption, MessageBoxButton.OK);
 }
