The example of multi-language station in MVC4

Environment: vs2012 ASP. Mvc4.

Implementation method: Resource resource file, according to the route rules in the lang parameter to determine which language mode is loaded

Find the relevant information on the Internet, the way to do a practice, the new project and other steps to avoid, the attention of the place, remember that convenient next use.

1: Add the resource file, remember to set the access mode of the resource file to public, otherwise the default is internal, outside will not access:

2: Add a routing rule, remember to precede the default routing rule, otherwise the new rule is useless, for detailed reasons please refer to this article

1 routes. ADD (NewRoute (2"{Lang}/{controller}/{action}/{id}",3New RouteValueDictionary (New{4 Lang ="En-US ", // 5 controller =  "account  ", 6 action =  "logon" , 7 ID = Urlparameter.optional 8 }), new Multilangroutehandler () //10));    

1PublicClassMultilangroutehandler:mvcroutehandler {2ProtectedOverrideIHttpHandler Gethttphandler (RequestContext requestcontext) {3string lang = requestcontext.routedata.values["Lang "". ToString ();  5 //thread.currentthread.currentculture = new CultureInfo (lang);  6 Thread.CurrentThread.CurrentUICulture = new CultureInfo (lang);  8 //return new Mvchandler (RequestContext);  9 return base. Gethttphandler (RequestContext); 10 }11}     

The CurrentUICulture in the code can refer to my previous article, which contains a detailed explanation.

3: Chinese and English switch the entrance.

1<Div>2@{3String controller = ViewContext.Controller.ValueProvider.GetValue ("Controller"). Rawvalue.tostring ();4 String action = ViewContext.Controller.ValueProvider.GetValue ("action"). Rawvalue.tostring (); 5 //string lang = ViewContext.Controller.ValueProvider.GetValue ("lang"). Rawvalue.tostring (); 6 }7 @Html. ActionLink ("Chinese", action, new {controller = controller, lang = "ZH-CN"}, new {@class = "btn-a" })8 @Html. ActionLink ("中文版", action, new {controller = controller, lang = "en-US"}, new {@class = "btn-a"}) C10>9 </div>            

4: Multi-language of plain text on interface

In fact, I have to follow the above article to write the test program, but the death of the resource files are not based on the Chinese and English to switch, I do not know if there is a problem, stuffy ~, then the MVC group inside Friends (ruthless water) introduced another article, I refer to rewrite the next, in this said sound ths ...

public static class Langhelper {//interface plain text multi-language public static string Getlangbykey (this HtmlHelper htmlhelper, String key) {Type ResourceType = (Thread.CurrentThread.CurrentUICulture.Name = = "en-us")? typeof (Resources.en            _us): typeof (RESOURCES.ZH_CN);            PropertyInfo p = resourcetype.getproperty (key); if (P! = null) return p.getvalue (null, NULL).            ToString ();        else return "undefined"; }//JS defines the multilingual popup public static string Langoutjsvar (this htmlhelper htmlhelper, string key) {Type R Esourcetype = (Thread.CurrentThread.CurrentUICulture.Name = = "en-us")?            typeof (Resources.en_us): typeof (RESOURCES.ZH_CN);            PropertyInfo p = resourcetype.getproperty (key); if (P! = null) return string. Format ("var {0} = ' {1} '", Key, p.getvalue (null, NULL).            ToString ()); else return string.        Format ("var {0} = ' {1} '", Key, "undefined"); }    } 

The view page calls directly with the function. such as:

5:displayname Multi-lingual

Redefine a Localdisplayname attribute that he inherits from Displaynameattribute

public class Localdisplayname:displaynameattribute {        private string _defaultname = "";        Public Type ResourceType {            get {return (Thread.CurrentThread.CurrentUICulture.Name = = "en-us")? typeof ( Resources.en_us): typeof (RESOURCES.ZH_CN); }        } public        string resourcename {            get;            Set;        }        Public Localdisplayname (String defaultname) {            _defaultname = defaultname;        }        public override string DisplayName {            get {                PropertyInfo p = resourcetype.getproperty (resourcename);                if (P! = null)                    return p.getvalue (null, NULL). ToString ();                else                    return _defaultname;}}    }

Change the display property to Localdisplayname on the model class

public class Account {        [Required]        [Localdisplayname ("User name", resourcename = "Userdisplay")]        public String UserName {get; set;}        [Required]        [Localdisplayname ("password", resourcename = "Pwddisplay")]        public string Pwd {get; set;}        [Required]        [Compare ("Pwd", Errormessageresourcename= "Confirmpwderrordisplay")]        [Localdisplayname ("Confirm password", resourcename = "Confirmpwddisplay")]        public string Confirmpwd {get; set;}                [Required]        [Localdisplayname ("Remember", resourcename = "Remdisplay")]        public bool RememberMe {get; set;}    }

Call mode:<div> @Html. labelfor (M = m.username) </div>

Implementation results:

Probably this basic realization, there is a errormessage is not good, have time to write. There are wrong places to correct everyone, thank you!

If it is to write the text of the database, how should you implement multi-lingual? What a good way to consult under.
