使用XML实现多语言的思路就是使用XML作为绑定的数据源。主要用到XmlDataProvider类.
使用XmlDataProvider.Source属性指定XML文件的路径或通过XmlDataProvider.Document指定XML文档对象XmlDataProvider.XPath属性指定绑定的路径。 新建一个WPF工程在debug目录下创建两个StrResource.xml文件分别置于en-US和zh-CN文件夹 debug\en-US\StrResource.xml 1 ?xml version1.0 encodingutf-8?
2 Language
3 Main_TitleLogin Form/Main_Title
4 Main_UserNameUserName/Main_UserName
5 Main_PasswordPassword/Main_Password
6 Main_ButtonLogin/Main_Button
7 Window1_TitleMain Form/Window1_Title
8 Window1_LabelWelcome/Window1_Label
9 /Language debug\zh-CN\StrResource.xml 1 ?xml version1.0 encodingutf-8?
2 Language
3 Main_Title登陆窗体/Main_Title
4 Main_UserName用户名/Main_UserName
5 Main_Password密码/Main_Password
6 Main_Button登陆/Main_Button
7 Window1_Title主界面/Window1_Title
8 Window1_Label欢迎/Window1_Label
9 /Language 主窗体XAML 1 StackPanel2 Label Content{Binding XPathMain_UserName}/Label3 TextBox/TextBox4 Label NamePassword Content{Binding XPathMain_Password}/Label5 TextBox/TextBox6 Button Height20 Margin10,5 BackgroundLightSkyBlue NameLogin Content{Binding XPathMain_Button} ClickLogin_Click/Button7 ComboBox Namecombox SelectedIndex0 SelectionChangedcombox_SelectionChanged8 ComboBoxItem中文/ComboBoxItem9 ComboBoxItemEnglish/ComboBoxItem
10 /ComboBox
11 /StackPanel 在后台代码中将XmlDataProvider对象绑定到界面即可 1 XmlDocument doc new XmlDocument();
2 XmlDataProvider xdp new XmlDataProvider();
3 doc.Load(./zh-CN/language.xml); //在切换语言时重新加载xml文档并重新绑定到界面即可
4 xdp.Document doc;
5 xdp.XPath /Language;
6 this.DataContext xdp; 运行效果如下 二、使用资源字典实现多语言切换
资源字典的实现方式也比较简单这是最常用的一种方式。
主要实现步骤是将要显示的字符绑定到资源文件然后在切换语言时用代码更改当前使用的资源文件即可。
创建一个WPF工程添加一个language目录再添加en-US和zh-CN目录。再分别在目录下创建资源字典文件内容如下
language\en-US.xaml 1 ResourceDictionary xmlnshttp://schemas.microsoft.com/winfx/2006/xaml/presentation2 xmlns:xhttp://schemas.microsoft.com/winfx/2006/xaml3 xmlns:sclr-namespace:System;assemblymscorlib4 s:String x:KeyMain.TitleMain Form/s:String5 s:String x:KeyMain.RibbonTab.SettingSetting/s:String6 s:String x:KeyMain.RibbonGroup.SettingAll Setting/s:String7 s:String x:KeyMain.RibbonButton.SettingSetting/s:String8 s:String x:KeyMain.RibbonButton.Setting.TitleSetting/s:String9 s:String x:KeyMain.RibbonButton.Setting.DescriptionAll Setting Include Language/s:String
10 s:String x:KeySetting.TitleSetting/s:String
11 s:String x:KeySetting.Tab.LanguageLanguage Setting/s:String
12 s:String x:KeySetting.Tab.Label.ChooseLanguagePlease choose a language/s:String
13 /ResourceDictionary language\zh-CN.xaml 1 ResourceDictionary xmlnshttp://schemas.microsoft.com/winfx/2006/xaml/presentation2 xmlns:xhttp://schemas.microsoft.com/winfx/2006/xaml3 xmlns:sclr-namespace:System;assemblymscorlib4 s:String x:KeyMain.Title主界面/s:String5 s:String x:KeyMain.RibbonTab.Setting设置/s:String6 s:String x:KeyMain.RibbonGroup.Setting全部设置/s:String7 s:String x:KeyMain.RibbonButton.Setting设置/s:String8 s:String x:KeyMain.RibbonButton.Setting.Title设置/s:String9 s:String x:KeyMain.RibbonButton.Setting.Description包括语言在内的全部设置/s:String
10 s:String x:KeySetting.Title设置/s:String
11 s:String x:KeySetting.Tab.Language语言设置/s:String
12 s:String x:KeySetting.Tab.Label.ChooseLanguage请选择一种语言/s:String
13 /ResourceDictionary 主窗体XAML 1 TabControl2 TabItem Header{DynamicResource Setting.Tab.Language}3 StackPanel4 TextBlock VerticalAlignmentTop Margin5,5,5,0 HorizontalAlignmentLeft Text{DynamicResource Setting.Tab.Label.ChooseLanguage}5 /TextBlock6 ComboBox Height20 VerticalAlignmentTop Margin5,10 Width200 HorizontalAlignmentLeft Namecombox_Language SelectionChangedcombox_Language_SelectionChanged7 ComboBoxItem中文/ComboBoxItem8 ComboBoxItemEnglish/ComboBoxItem9 /ComboBox
10 /StackPanel
11 /TabItem
12 /TabControl 后台代码 private void combox_Language_SelectionChanged(object sender, SelectionChangedEventArgs e){ChangeLanguage(this.combox_Language.SelectedIndex);}/// summary/// 切换 语言/// /summary/// param nameindex/parampublic void ChangeLanguage(int index){ResourceDictionary rd new ResourceDictionary();switch(index){case 0:rd.Source new Uri(Language/zh-CN.xaml, UriKind.Relative);break;case 1:rd.Source new Uri(Language/en-US.xaml, UriKind.Relative);break;default:break;} Application.Current.Resources.MergedDictionaries[0] rd;} 运行效果如下 三、使用资源文件实现多语言切换
这种方式的实现也比较简单也是将字符绑定到资源文件(.resx)
但需要注意的是这种方式是静态的不能实现动态切换。只能在启动时更改。 创建一个WPF工程添加一个字符资源文件StrResources.resx作为默认的字符资源文件再添加一个StrResources.zh-CN.resx做为中文字符资源因为我用于演示的这台电脑系统是英文的
注意需要将访问修饰符改为public否则运行会报错 主界面XAML 1 Grid2 Label HorizontalAlignmentLeft VerticalAlignmentTop Content{x:Static local:StrResources.ChangeLanguage}/Label3 ComboBox HorizontalAlignmentLeft VerticalAlignmentTop Margin120,5,0,0 Width200 Namecombox_Culture4 ComboBoxItem Content{x:Static local:StrResources.zh_CN}/ComboBoxItem5 ComboBoxItem Content{x:Static local:StrResources.en_US}/ComboBoxItem6 /ComboBox7 8 Button Content{x:Static local:StrResources.OK} Width88 Height28 HorizontalAlignmentRight VerticalAlignmentBottom Margin0,0,120,0/9 Button Content{x:Static local:StrResources.Cancel} Width88 Height28 HorizontalAlignmentRight VerticalAlignmentBottom Margin0,0,10,0/
10 /Grid 主界面后台逻辑 1 public partial class MainWindow : Window2 {3 public MainWindow()4 {5 InitializeComponent();6 7 LoadCulture();8 }9
10 public void LoadCulture()
11 {
12 if(CultureInfo.CurrentCulture.Name zh-CN)
13 {
14 combox_Culture.SelectedIndex 0;
15 }
16 else
17 {
18 combox_Culture.SelectedIndex 1;
19 }
20 }
21 } 在Application类的Startup事件中可以切换语言但在程序运行后无法再切换 1 public partial class App : Application2 {3 private void Application_Startup(object sender, StartupEventArgs e)4 {5 //在这里可以更改语言6 ChangeCulture(0);7 }8 9 public void ChangeCulture(int index)
10 {
11 string cultureName ;
12
13 switch (index)
14 {
15 case 0:
16 cultureName zh-CN;
17 break;
18 case 1:
19 cultureName en-US;
20 break;
21 default:
22 cultureName en-US;
23 break;
24 }
25
26 Thread.CurrentThread.CurrentCulture new CultureInfo(cultureName);
27 Thread.CurrentThread.CurrentUICulture new CultureInfo(cultureName);
28 }
29 } 运行效果 四、使用json文件实现多语言切换
这种方式实现多语言切换有点麻烦但可以使用json作为语言文件其它格式文件其实也可以.txt .xml .csv。
这种方式的实现原理是使用索引器方法查找每个字段值然后绑定到界面上。支持动态切换
在debug目录下创建
zh-CN.json 1 {
2 OK: 确定,
3 Cancel: 取消,
4 ChangeLanguage: 更改语言,
5 zh_CN: 中文,
6 en_US: English
7 } en-US.json 1 {
2 OK: OK,
3 Cancel: Cancel,
4 ChangeLanguage: Change language,
5 zh_CN: 中文,
6 en_US: English
7 } 封装一个绑定通知类这个类用于切换语言时绑定的通知更新。 1 /// summary2 /// 绑定通知类3 /// /summary4 public class NotifyPropertyChanged : INotifyPropertyChanged5 {6 public event PropertyChangedEventHandler PropertyChanged;7 8 protected void RaisePropertyChanged(string PropertyName)9 {
10 PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(PropertyName));
11 }
12
13 protected void OnPropertyChanged([CallerMemberName] string PropertyName null)
14 {
15 RaisePropertyChanged(PropertyName);
16 }
17
18 protected void RaiseAllChanged()
19 {
20 RaisePropertyChanged();
21 }
22 } 创建一个语言字段类这个类用于封装所有的语言字段。这一步确实就比较麻烦了每个字段都得封装一个属性。 1 /// summary2 /// 语言字段类3 /// /summary4 public class LanguageFields : NotifyPropertyChanged5 {6 /// summary7 /// 需要被重写的方法 用于获取语言字段值8 /// /summary9 /// param namekey/param
10 /// returns/returns
11 protected virtual string GetValue(string key) ;
12
13 protected virtual void SetValue(string Key, string value) { }
14
15 /// summary
16 /// 使用CallerMemberName特性传递当前属性名
17 /// /summary
18 /// param namepropertyName/param
19 /// returns/returns
20 string Get([CallerMemberName] string propertyName null)
21 {
22 return GetValue(propertyName);
23 }
24
25 void Set(string value, [CallerMemberName] string propertyName null)
26 {
27 SetValue(propertyName, value);
28 }
29
30 public string OK { get Get(); set Set(value); }
31 public string Cancel { get Get(); set Set(value); }
32 public string ChangeLanguage { get Get(); set Set(value); }
33 public string zh_CN { get Get(); set Set(value); }
34 public string en_US { get Get(); set Set(value); }
35 } 创建一个语言切换帮助类这个类可以对当前使用的语言以及字段值进行操作 1 public class LanguageHelper : LanguageFields2 { 3 private JObject currentLanguage; //当前语言的JObject对象 4 private static readonly string dir Environment.CurrentDirectory; //语言文件夹5 private CultureInfo currentCulture; //当前语言6 7 public static LanguageHelper Instance { get; } new LanguageHelper();8 9 LanguageHelper()
10 {
11 CurrentCulture CultureInfo.CurrentCulture;
12 }
13
14 /// summary
15 /// 当前语言属性 当值更新时加载语言并更新绑定
16 /// /summary
17 public CultureInfo CurrentCulture
18 {
19 get currentCulture;
20 set
21 {
22 currentCulture value;
23 CultureInfo.CurrentUICulture value;
24 currentLanguage LoadLang(value.Name);
25 LanguageChanged?.Invoke(value);
26 RaiseAllChanged();
27 }
28 }
29
30 /// summary
31 /// 加载语言文件
32 /// /summary
33 /// param nameLanguageId/param
34 /// returns/returns
35 JObject LoadLang(string LanguageId)
36 {
37 try
38 {
39 var filePath System.IO.Path.Combine(dir, ${LanguageId}.json);
40 return JObject.Parse(File.ReadAllText(filePath));
41 }
42 catch
43 {
44 return new JObject();
45 }
46 }
47
48 /// summary
49 /// 索引器方法 用于查找语言字段值
50 /// /summary
51 /// param nameKey/param
52 /// returns/returns
53 public string this[string Key]
54 {
55 get
56 {
57 if (Key null)
58 return ;
59
60 if (currentLanguage ! null currentLanguage.TryGetValue(Key, out var value) value.ToString() is string s !string.IsNullOrWhiteSpace(s))
61 return s;
62
63 return Key;
64 }
65 }
66
67 /// summary
68 /// 重写 GetValue方法调用索引器方法
69 /// /summary
