WPF国际化

环境：

VisualStudio2022

ResXManager 1.84.6269.0

实现方法

step1：安装VisualStudio扩展工具 - ResXManager

step2：创建资源文件

step3：设置访问级别

step4：打开 ResXManager

step5：设置/添加语言

step6：添加语言管理类

public class LanguageManager : INotifyPropertyChanged
{
    /// <summary>
    /// 资源
    /// </summary>
    private readonly ResourceManager _resourceManager;

    /// <summary>
    /// 懒加载
    /// </summary>
    private static readonly Lazy<LanguageManager> _lazy = new Lazy<LanguageManager>(() => new LanguageManager());
    public static LanguageManager Instance => _lazy.Value;
    public event PropertyChangedEventHandler PropertyChanged;

    public LanguageManager()
    {
        //获取此命名空间下Resources的Lang的资源，Lang可以修改
        _resourceManager = new ResourceManager("WpfAppZBC.Resources.lang", typeof(LanguageManager).Assembly);
    }

    /// <summary>
    /// 索引器的写法，传入字符串的下标
    /// </summary>
    /// <param name="name"></param>
    /// <returns></returns>
    /// <exception cref="ArgumentNullException"></exception>
    public string this[string name]
    {
        get
        {
            if (name == null)
            {
                throw new ArgumentNullException(nameof(name));
            }
            return _resourceManager.GetString(name);
        }
    }

    public void ChangeLanguage(CultureInfo cultureInfo)
    {
        CultureInfo.CurrentCulture = cultureInfo;
        CultureInfo.CurrentUICulture = cultureInfo;
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("item[]"));  //字符串集合，对应资源的值
    }
}

step7：在xaml中引用资源

<Window
    x:Class="WpfAppZBC.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:local="clr-namespace:WpfAppZBC"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Title="{Binding [mainWindow], Source={x:Static local:LanguageManager.Instance}}"
    Width="800"
    Height="450"
    mc:Ignorable="d">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="auto" />
            <RowDefinition />
        </Grid.RowDefinitions>
        <Menu>
            <MenuItem Header="{Binding [file], Source={x:Static local:LanguageManager.Instance}}">
                <MenuItem Header="{Binding [open], Source={x:Static local:LanguageManager.Instance}}" />
                <MenuItem Header="{Binding [save], Source={x:Static local:LanguageManager.Instance}}" />
                <MenuItem Header="{Binding [saveAs], Source={x:Static local:LanguageManager.Instance}}" />
                <MenuItem Header="{Binding [exit], Source={x:Static local:LanguageManager.Instance}}" />
            </MenuItem>
            <MenuItem Header="{Binding [edit], Source={x:Static local:LanguageManager.Instance}}">
                <MenuItem Header="{Binding [cut], Source={x:Static local:LanguageManager.Instance}}" />
                <MenuItem Header="{Binding [copy], Source={x:Static local:LanguageManager.Instance}}" />
                <MenuItem Header="{Binding [paste], Source={x:Static local:LanguageManager.Instance}}" />
                <MenuItem Header="{Binding [delete], Source={x:Static local:LanguageManager.Instance}}" />
            </MenuItem>
            <MenuItem Header="{Binding [system], Source={x:Static local:LanguageManager.Instance}}">
                <MenuItem Header="{Binding [internationalization], Source={x:Static local:LanguageManager.Instance}}">
                    <MenuItem
                        x:Name="menuItemZHCN"
                        Click="menuItemZHCN_Click"
                        Header="中文简体" />
                    <MenuItem
                        x:Name="menuItemZHHANT"
                        Click="menuItemZHHANT_Click"
                        Header="中文繁体" />
                    <MenuItem
                        x:Name="menuItemEN"
                        Click="menuItemEN_Click"
                        Header="English" />
                </MenuItem>
            </MenuItem>
        </Menu>
        <TextBlock
            Grid.Row="1"
            HorizontalAlignment="Center"
            VerticalAlignment="Center"
            FontSize="65"
            Text="{Binding [contentText], Source={x:Static local:LanguageManager.Instance}}" />
    </Grid>
</Window>

step8：语言切换

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void menuItemZHCN_Click(object sender, RoutedEventArgs e)
    {
        LanguageManager.Instance.ChangeLanguage(new CultureInfo("zh-CN"));
    }

    private void menuItemZHHANT_Click(object sender, RoutedEventArgs e)
    {
        LanguageManager.Instance.ChangeLanguage(new CultureInfo("zh-Hant"));
    }

    private void menuItemEN_Click(object sender, RoutedEventArgs e)
    {
        LanguageManager.Instance.ChangeLanguage(new CultureInfo("en"));
    }
}
