WPF 实际国际化多语言界面

         前段时候写了一个WPF多语言界面处理,个人感觉还行,分享给大家.使用合并字典,静态绑定,动态绑定.样式等东西

效果图

       定义一个实体类LanguageModel,实际INotifyPropertyChanged接口

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;

namespace WpfApplication1
{
    public class LanguageModel : INotifyPropertyChanged
    {
        private string _languageCode;
        private string _languageName; 
        private string _languageDisplayName;
        private string _resourcefile;
        private bool _languageenabled;
        /// <summary>
        /// 语言代码  如en,zh
        /// </summary>
        public string LanguageCode
        {
            get { return _languageCode; }
            set { _languageCode = value; OnPropertyChanged("LanguageCode"); }
        }
        /// <summary>
        /// 语言名称  如:中国 ,English
        /// </summary>
        public string LanguageName
        {
            get { return _languageName; }
            set { _languageName = value; OnPropertyChanged("LanguageName"); }
        }
        /// <summary>
        /// 语言名称  如:中国 ,English
        /// </summary>
        public string LanguageDisplayName
        {
            get { return _languageDisplayName; }
            set { _languageDisplayName = value; OnPropertyChanged("LanguageDisplayName"); }
        }

        /// <summary>
        /// 语言资源文件地址 
        /// </summary>
        public string Resourcefile
        {
            get { return _resourcefile; }
            set { _resourcefile = value; OnPropertyChanged("Resourcefile"); }
        }

        /// <summary>
        /// 是否启用此语言配置文件
        /// </summary>
        public bool LanguageEnabled
        {
            get { return _languageenabled; }
            set { _languageenabled = value; OnPropertyChanged("LanguageEnabled"); }            
        }

        protected void OnPropertyChanged(string name)
        {
            PropertyChangedEventHandler handler = PropertyChanged;
            if (handler != null)
            {
                handler(this, new PropertyChangedEventArgs(name));
            }
        }

        public event PropertyChangedEventHandler PropertyChanged;
    }
}

核心类 I18N

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.IO;



namespace WpfApplication1
{
    public class Language : LanguageModel
    {
        private ResourceDictionary _resource;

        public ResourceDictionary Resource
        {
            get { return _resource; }
            set { _resource = value; OnPropertyChanged("Resource"); }
        }
    }


    /// <summary>
    /// 国际化     注:语言资源文件在VS2010的属性设置   复制到输出目录:始终复制     生成操作:内容
    /// 资源文件 LanguageCode ,LanguageName, LanguageDisplayName,LanguageEnabled 字段必填
    /// </summary>
    public class I18N
    {
        private static string _currentLanguage = "zh-cn";
        /// <summary>
        /// 设置或获取语言编码,如果设置失败,则可能语言资源文件错误
        /// </summary>
        public static string CurrentLanguage
        {
            get { return _currentLanguage; }
            set
            {                
                if(UpdateCurrentLanguage(value))
                    _currentLanguage = value;
            }
        }

        private static List<Language> _languageIndex;
        /// <summary>
        /// 所有语言索引
        /// </summary>
        public static List<Language> LanguageIndex
        {

        }      

        /// <summary>
        /// 初始化,加载语言目录下的所有语言文件
        /// </summary>
        public static void Initialize()
        {
            _languageIndex = new List<Language>();
            string dirstring = AppDomain.CurrentDomain.BaseDirectory + "Resource\Language\";
            DirectoryInfo directory = new DirectoryInfo(dirstring);
            FileInfo[] files = directory.GetFiles();
            foreach (var item in files)
            {
                Language language = new Language();
                ResourceDictionary rd = new ResourceDictionary();
                rd.Source = new Uri(item.FullName);
                language.LanguageCode = rd["LanguageCode"] == null ? "未知" : rd["LanguageCode"].ToString();
                language.LanguageName = rd["LanguageName"] == null ? "未知" : rd["LanguageName"].ToString();
                language.LanguageDisplayName = rd["LanguageDisplayName"] == null ? "未知" : rd["LanguageDisplayName"].ToString();
                language.LanguageEnabled = rd["LanguageEnabled"] == null ? false : bool.Parse(rd["LanguageEnabled"].ToString());
                language.Resourcefile = item.FullName;
                language.Resource = rd;
                if(language.LanguageEnabled)
                    _languageIndex.Add(language);
            }
        }

        /// <summary>

        /// </summary>
        private static bool UpdateCurrentLanguage(string LanguageCode)
        {
            if (LanguageIndex.Exists(P => P.LanguageCode == LanguageCode&&P.LanguageEnabled==true))
            {
                Language language = LanguageIndex.Find(P => P.LanguageCode == LanguageCode&&P.LanguageEnabled==true);
                if (language != null)
                {
                    foreach (var item in LanguageIndex)
                    {
                        Application.Current.Resources.MergedDictionaries.Remove(item.Resource);
                    }
                    Application.Current.Resources.MergedDictionaries.Add(language.Resource);
                    return true;
                }
            }
            return false;
        }

        public static string GetLanguageValue(string key)
        {
            ResourceDictionary rd = Application.Current.Resources;
            if (rd == null)
                return "";
            object obj = rd[key];
            return obj == null ? "" : obj.ToString();
        }

    }
}

 资料文件直接使用 XX.xaml文件    注:语言资源文件在VS2010的属性设置   复制到输出目录:始终复制     生成操作:内容   ,确保xaml文件会复制到项目中,而不是编译到dll中

<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">
    <sys:String x:Key="LanguageCode">zh</sys:String>
    <sys:String x:Key="LanguageName">简休中文</sys:String>
    <sys:String x:Key="LanguageDisplayName">简休中文</sys:String>
    <sys:String x:Key="LanguageEnabled">true</sys:String>

    

    <sys:String x:Key="LanguageLanguage">语言：</sys:String>
    <sys:String x:Key="LanguageA">字段A：</sys:String>
    <sys:String x:Key="LanguageB">字段B：</sys:String>
    <sys:String x:Key="LanguageC">字段C：</sys:String>


</ResourceDictionary>

默认语言可以在App.xaml里设置

<Application x:Class="WpfApplication1.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             Startup="Application_Startup"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Resource/Language/zh.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

界面上使用动态绑定或静态绑定资源  (DynamicResource  ,StaticResource) ,  DataGrid表头使用HeaderSytle

      动态绑定:可以实时更新语言种类.

　　静态绑定,不能实时更新语言种类,如:在登录的时候已经确实语言种类,进入系统后而不能更改.

示例效果界面
