程序的多语言支持解决方案（WinForm+WebForm)

主要代码不多：

Thread.CurrentThread.CurrentCulture  =   new  CultureInfo(lang); 
Thread.CurrentThread.CurrentUICulture  =  Thread.CurrentThread.CurrentCulture; 
 
public   static  System.Resources.ResourceManager rm  =   null ; 
rm  =   new  System.Resources.ResourceManager( " WindowAppTest.Languages.Language " ,Assembly.GetExecutingAssembly());

详细代码（Web程序）
------------------------------------------------------------------------------------
Global.asax:
 
 

  protected   void  Application_BeginRequest(Object sender, EventArgs e) 
   { 
   if(Request.Cookies["resource"] != null && Request.Cookies["resource"].Value.Trim() != "") 
   { 
    Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(Request.Cookies["resource"].Value.Trim()); 
   } 
   else 
   { 
    Thread.CurrentThread.CurrentCulture = new CultureInfo(System.Configuration.ConfigurationSettings.AppSettings["DefaultLanguage"]); 
   } 
   Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture; 
  }  

/*------------------------------------------------------------------------------------
使用的时候：
   System.Resources.ResourceManager rm = new System.Resources.ResourceManager("TestWebApp.Languages.Language",typeof(WebForm1).Assembly);
   Response.Write(rm.GetString("Message"));
