Example of multi-language website construction in mvc4

Environment: vs2012 Asp.net mvc4.

Implementation Method: resource file, based on the Lang parameter in the routing rule to determine which language to load

I found the relevant information on the Internet and made an exercise by myself. The steps such as creating a project are no longer required. Please note that it is easy to use it next time.

1: Add a resource file. Remember to set the access mode of the resource file to public. Otherwise, the default access mode is internal, and access from outside will fail:

 

2: Add a routing rule. Remember to add it before the default routing rule. Otherwise, the new rule is useless. For details, refer to this article.

1 routes. add (new route (2 "{Lang}/{controller}/{action}/{ID}", 3 new routevaluedictionary (New {4 lang = "En-us ", // The default value is e File 5 controller = "Account", 6 action = "Logon", 7 id = urlparameter. optional 8}), 9 new multilangroutehandler () // This class is mainly used to get the current Lang value 10 through gethttphandler ));

 

 1 public class MultiLangRouteHandler : MvcRouteHandler { 2         protected override IHttpHandler GetHttpHandler(RequestContext requestContext) { 3             string lang = requestContext.RouteData.Values["lang"].ToString(); 4  5             //Thread.CurrentThread.CurrentCulture = new CultureInfo(lang); 6             Thread.CurrentThread.CurrentUICulture = new CultureInfo(lang); 7  8             //return new MvcHandler(requestContext); 9             return base.GetHttpHandler(requestContext);10         }11     }

For details about currentuiculture in the code, refer to the previous article.

3: entry for switching between Chinese and English.

1 <div> 2 @ {3 string 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 ("English", action, new {controller = controller, lang = "En-us"}, new {@ class = "BTN-a"}) 9 </div>

4: multiple languages of common text on the Interface

In fact, I wrote the test program according to the article above, but the dead resource file is not switched based on Chinese and English. I don't know if there is a problem or not ~, Later, my friend (heartless water) in the MVC group introduced another article. I wrote it with reference. Here I say ths...

Public static class langhelper {// multilingual public static string getlangbykey (this 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 definition multilingual pop-up box public static string langoutjsvar (this 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 string. format ("Var {0} = '{1}'", key, P. getvalue (null, null ). tostring (); else return string. format ("Var {0} = '{1}'", key, "undefined ");}}

The view page calls the function directly. For example: <H2> @ html. getlangbykey ("logondisplay") </H2>

5: Multilingual displayname

Redefine the localdisplayname attribute, which 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 attribute to localdisplayname in 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 method: <div> @ html. labelfor (M => M. username) </div>

 

Effect:

 

This is basically achieved. There is an errormessage which is not complete yet. If you have time, write it again. If anything is wrong, please correct me. Thank you!
