WPF 多语言切换
1. 添加资源字典
新增两个资源字典,里面分别存储不同语言的文本
<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=netstandard"><s:String x:Key="btnConfirm">确认</s:String><s:String x:Key="btnCancle">取消</s:String>
</ResourceDictionary>
<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=netstandard"><s:String x:Key="btnConfirm">Sure</s:String><s:String x:Key="btnCancle">NoSure</s:String>
</ResourceDictionary>
.net core
环境下没有自动引入system命名空间,在这里根据提示引入xmlns:s="clr-namespace:System;assembly=netstandard"
2. 配置资源字典
在ResourceDictionary中把新增的资源字典加进去
<Application x:Class="wpfMultiLanguage.App"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:local="clr-namespace:wpfMultiLanguage"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>
2.1 在这里需要注意的是Source路径的填写
如果你的资源字典文件位于与当前XAML文件相同的目录下,你可以直接写文件名(包括扩展名 .xaml),就直接写<ResourceDictionary Source="en-us.xaml" />
就行了
如果资源字典位于子目录下,例如一个名为 Resources 的子目录,你需要包含子目录名,变成<ResourceDictionary Source="Resources/en-us.xaml" />
如果资源字典位于父目录下,你可以使用 … 来表示父目录。
<ResourceDictionary Source="../en-us.xaml" />
对于更复杂的项目结构或对于组件库中的资源,你可能需要使用包路径(Pack URI)。包路径的格式通常如下:
<ResourceDictionary Source="pack://application:,,,/wpfMultiLanguage;component/Resources/en-us.xaml" />
3. 在页面上使用
使用动态资源进行绑定
<Window x:Class="wpfMultiLanguage.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"mc:Ignorable="d"Title="MainWindow" Height="450" Width="800"><StackPanel><StackPanel.Resources><Style TargetType="Button"><Setter Property="Width" Value="120"/><Setter Property="Height" Value="25"/><Setter Property="Margin" Value="5"/></Style></StackPanel.Resources><Button Content="中文" Click="btnChinese_Click"></Button><Button Content="英语" Click="btnEnglish_Click"></Button><Button Content="{DynamicResource btnConfirm}"></Button><Button Content="{DynamicResource btnCancle}"></Button></StackPanel>
</Window>
给上面两个按钮绑定点击事件,实现语言切换
private void btnChinese_Click(object sender, RoutedEventArgs e){ChangeLan("zh-cn");}private void btnEnglish_Click(object sender, RoutedEventArgs e){ChangeLan("en-us");}private void ChangeLan(string lan){List<ResourceDictionary> dictionaryList = Application.Current.Resources.MergedDictionaries.ToList();string requestedCulture = $"Resources/{lan}.xaml";ResourceDictionary resourceDictionary = dictionaryList.FirstOrDefault(d => d.Source.OriginalString.Equals(requestedCulture));Application.Current.Resources.MergedDictionaries.Remove(resourceDictionary);Application.Current.Resources.MergedDictionaries.Add(resourceDictionary);}
4. 演示
点英文按钮
