C# Winform软件多语言（汉语、英语。。。）界面的切换，低耦合

Winform软件多语言切换，个人见解，降低软件对语言展示的耦合度。

1、设计图（自己瞎画的呵呵）

2、做的小demo，界面如下

3、下面是代码展示部分

1）Form1代码展示

 namespace WindowsFormsApplication1
 {
     public partial class Form1 : Form
     {
         public Form1()
         {
             InitializeComponent();
             SetLanguage();
         }

         private void SetLanguage()
         {
             this.lbUserName.Text = GlobalData.GlobalLanguage.Login_UserName;
             this.lbPwd.Text = GlobalData.GlobalLanguage.Login_UserPwd;
             this.btnLogin.Text = GlobalData.GlobalLanguage.Login_Login;
         }
     }
 }

2）GlobalData类代码展示

 namespace WindowsFormsApplication1
 {
     public class GlobalData
     {
         /// <summary>
         /// 系统语言（Chinese（中文），English（英文）。。。）
         /// </summary>
         public static string SystemLanguage = System.Configuration.ConfigurationManager.AppSettings["Language"];

         private static Language globalLanguage;
         public static Language GlobalLanguage
         {
             get
             {
                 if (globalLanguage == null)
                 {
                     globalLanguage = new Language();
                     return globalLanguage;
                 }
                 return globalLanguage;
             }
         }

     }
 }

3）Language类代码展示

 namespace WindowsFormsApplication1
 {
     public class Language
     {
         #region 登陆界面
         public string Login_UserName = "";
         public string Login_UserPwd = "";
         public string Login_Login = "";
         #endregion               

         protected Dictionary<string, string> DicLanguage = new Dictionary<string, string>();
         public Language()
         {
             XmlLoad(GlobalData.SystemLanguage);
             BindLanguageText();
         }

         /// <summary>
         /// 读取XML放到内存
         /// </summary>
         /// <param name="language"></param>
         protected void XmlLoad(string language)
         {
             try
             {
                 XmlDocument doc = new XmlDocument();
                 string address = AppDomain.CurrentDomain.BaseDirectory + "Languages\\" + language + ".xml";
                 doc.Load(address);
                 XmlElement root = doc.DocumentElement;

                 XmlNodeList nodeLst1 = root.ChildNodes;
                 foreach (XmlNode item in nodeLst1)
                 {
                     DicLanguage.Add(item.Name, item.InnerText);
                 }
             }
             catch (Exception ex)
             {
                 throw ex;
             }
         }

         public void BindLanguageText()
         {
             Login_UserName = DicLanguage["Login_UserName"];
             Login_UserPwd = DicLanguage["Login_UserPwd"];
             Login_Login = DicLanguage["Login_Login"];
         }
     }
 }

4）App.config代码展示

 <?xml version="1.0" encoding="utf-8" ?>
 <configuration>
   <appSettings>
     <!-- Language的值只能是Chinese（中文），English（英文） -->
     <add key="Language" value="English"/>
   </appSettings>
 </configuration>

5）English.xml代码展示

 <?xml version="1.0" encoding="utf-8" ?>
 <English>
   <Login_UserName>UserName:</Login_UserName>
   <Login_UserPwd>Password:</Login_UserPwd>
   <Login_Login>Login</Login_Login>
 </English>

6）Chinese.xml代码展示

 <?xml version="1.0" encoding="utf-8" ?>
 <Chinese>
   <Login_UserName>用户名：</Login_UserName>
   <Login_UserPwd>密码：</Login_UserPwd>
   <Login_Login>登录</Login_Login>
 </Chinese>

4、如果想要换法语则只需要在App.config中配置换成French，然后再添加一个French.xml，内容和其他语言模板一样把内容换成法语则可。

5、OK。
