WPF多语言切换

最近在用wpf做一个项目，需要提供中文和俄文切换，这是效果图

1.在程序根目录下新建两个资源词典文件，注意加上：xmlns:sys="clr-namespace:System;assembly=mscorlib”

中文：“zh-CN.xaml”

</ResourceDictionary>

俄文：“ru.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"
                    xmlns:local="clr-namespace:JNTApp">
    
    <sys:String x:Key="WinLogin">войти</sys:String>
    <sys:String x:Key="txtAccount">Логин：</sys:String>
    <sys:String x:Key="txtPasswd">Пароль：</sys:String>
    <sys:String x:Key="cobChoose">выбор языка：</sys:String>
    <sys:String x:Key="chkSave">запомнить Пароль</sys:String>
    <sys:String x:Key="chkAuto">автоматический вход</sys:String>
    <sys:String x:Key="btnLogin">войти</sys:String>
    <sys:String x:Key="btnCancel">отменить</sys:String>
    <sys:String x:Key="cobCh">китайский язык</sys:String>
    <sys:String x:Key="cobEw">русский язык</sys:String>

</ResourceDictionary>

定义完成之后，在界面引用; Text="{DynamicResource txtAccount}"

2.在App.xaml加上

<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="ru.xaml"/>
                <ResourceDictionary Source="zh-CN.xaml"/>
           </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

3.在App.xaml.cs加一个方法

private void Application_Startup(object sender, StartupEventArgs e)
{

Application currApp = Application.Current;
currApp.StartupUri = new Uri("SignWindow.xaml", UriKind.RelativeOrAbsolute);

//调用方法
LoadLanguage();
}

//加载语言
        private void LoadLanguage()
        {
            CultureInfo currentCultureInfo = CultureInfo.CurrentCulture;
            ResourceDictionary langRd = null;
            try
            {
                langRd =
                Application.LoadComponent(
                new Uri(currentCultureInfo.Name + ".xaml", UriKind.Relative)) as ResourceDictionary;
            }
            catch
            {
            }
            if (langRd != null)
            {
                if (this.Resources.MergedDictionaries.Count > 0)
                {
                    this.Resources.MergedDictionaries.Clear();
                }
                this.Resources.MergedDictionaries.Add(langRd);
            }
        }

4.登录时，首先初始化默认是哪种语言，我这边默认的是中文

public SignWindow()
        {
            InitializeComponent();
            currentLang = "zh-CN";
            Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("zh-CN");

}

5.切换语言

//登录成功后跳转到主界面

private MainWindow MainWindow;

/// <summary>
        /// 语言选择
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
       private void cobChoose_DropDownClosed(object sender, EventArgs e)
        {
            string language = this.cobChoose.Text;

            //语言类型
            string languageType = "";
            if (!string.IsNullOrEmpty(language))
            {
                switch (language)
                {
                    case "中文": languageType = "zh-CN"; break;
                    case "俄文": languageType = "ru"; break;
                    case "китайский язык": languageType = "zh-CN"; break;
                    case "русский язык": languageType = "ru"; break;

}
Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("zh-CN");

                 //切换语言的方法
                ChangeLanguage.change(languageType, this);
                if (MainWindow != null)
                {
                    ChangeLanguage.change(languageType, MainWindow);
                }
                currentLang = languageType;

                 //定义一个session来保存当前选中的语言，供其它界面使用
                Variable.LanguageSeesion = currentLang;
            }
        }

6.切换语言的方法，定义一个ChangeLanguage类

static class ChangeLanguage
{

     // 这个是window窗体
        public static void change(string currentLang,Window w)
        {
          System.Windows.ResourceDictionary langRd = null;

            CultureInfo currentCultureInfo = CultureInfo.CurrentCulture;
            try
            {
                langRd =
               System.Windows.Application.LoadComponent(
                new Uri(currentLang + ".xaml", UriKind.Relative)) as ResourceDictionary;
            }
            catch
            {
            }
            if (langRd != null)
            {
                if (w.Resources.MergedDictionaries.Count > 0)
                {
                    w.Resources.MergedDictionaries.Clear();
                }
                w.Resources.MergedDictionaries.Add(langRd);
            }

}

//这个是page页面
        public static void changePage(string currentLang)
        {
            System.Windows.ResourceDictionary langRd = null;

            CultureInfo currentCultureInfo = CultureInfo.CurrentCulture;
            try
            {
                langRd =
               System.Windows.Application.LoadComponent(
                new Uri(currentLang + ".xaml", UriKind.Relative)) as ResourceDictionary;
            }
            catch
            {
            }
            if (langRd != null)
            {
                Application.Current.Resources.MergedDictionaries.Clear();
                Application.Current.Resources.MergedDictionaries.Add(langRd);

            }

}

第一次写博客，只管贴代码，有些地方可能没说清楚，不过看代码应该能看清楚吧
