ASP. net mvc Internationalization

 

This post in the blog garden is already comprehensive, but I think it is not elegant enough. It seems like a mess, and this old man's post abroad is neat and tidy, A simple record is as follows:

General international Processing Methods

 Public   Class User {[required (errormessageresourcename =" Validation_required ", Errormessageresourcetype = Typeof (Modeltranslations)] [localizeddisplaynameattribute (" User_id ", Nameresourcetype = Typeof (Modeltranslations)] Public   Int Id { Get ;Set ;} [Required (errormessageresourcename =" Validation_required ", Errormessageresourcetype = Typeof (Modeltranslations)] [stringlength (40, errormessageresourcename =" Validation_stringlength ", Errormessageresourcetype = Typeof (Modeltranslations)] [localizeddisplaynameattribute (" User_firstname ", Nameresourcetype = Typeof (Modeltranslations)] Public   String Firstname {Get ; Set ;} [Required (errormessageresourcename =" Validation_required ", Errormessageresourcetype = Typeof (Modeltranslations)] [stringlength (40, errormessageresourcename =" Validation_stringlength ", Errormessageresourcetype = Typeof (Modeltranslations)] [localizeddisplaynameattribute (" User_lastname ", Nameresourcetype = Typeof (Modeltranslations)] Public   String Lastname { Get ; Set ;}}

We can see that it is confusing.

 Public   Class User {[required] [localizeddisplaynameattribute (" User_id ")] Public   Int Id { Get ; Set ;} [Required] [stringlength (40)] [localizeddisplaynameattribute (" User_firstname ")] Public  String Firstname { Get ; Set ;} [Required] [stringlength (40)] [localizeddisplaynameattribute (" User_lastname ")] Public   String Lastname { Get ; Set ;}}

Is it much more neat, but the cost of cleanliness is to writeCodeOf

 Public   Class Requiredattriations: system. componentmodel. dataannotations. requiredattriations {Private   String _ Displayname; Public Requiredattribute () {errormessageresourcename =" Validation_required ";} Protected   Override Validationresult isvalid ( Object   Value , Validationcontext) {_ displayname = validationcontext. displayname; Return   Base . Isvalid ( Value , Validationcontext );} Public   Override   String Formaterrormessage ( String Name) {var MSG = Your ageservice. instance. Translate (errormessageresourcename ); Return   String . Format (MSG, _ displayname );}}

This is the implementation code for verifying properties.

Ublic Class Localizeddisplaynameattribute: displaynameattribute { Private Propertyinfo _ nameproperty; Private Type _ resourcetype;Public Localizeddisplaynameattribute ( String Classname, String Propertyname ): Base (Classname + (propertyname = Null ? " _ Class ":(" _ "+ Propertyname ))){} Public   Override   String Displayname { Get { Return Languageservice. instance. Translate ( Base . Displayname )?? " ** "+ Base . Displayname +" ** ";}}}

This is the implementation code for implementing the displayname attribute.

 Public   Class Languageservice { Private   Static Required ageservice _ instance = New Languageservice (); Private List <ResourceManager> _ resourcemanagers = New List <ResourceManager> (); Private Languageservice (){} Public   Static Languageservice instance { Get { Return _ Instance ;}} Public   Void Add (ResourceManager MGR) {_ resourcemanagers. Add (MGR );} Public   String Translate ( String Key ){ Foreach (VAR itemIn _ Resourcemanagers) {VaR Value = Item. getstring (key ); If ( Value ! = Null ) Return   Value ;} Return   Null ;}}

This is the code for managing resources dependent on the above class.

However, the above solution is still problematic for client verification. The following is a simple implementation:

 Public   Class Requiredattributeadapter: dataannotationsmodelvalidator <requiredattribute> { Public Requiredattributeadapter (modelmetadata metadata, controllercontext context, requiredattribute attribute ): Base (Metadata, context, attribute ){} Public   Static   Void Selfregister () {dataannotationsmodelvalidatorprovider. registeradapter ( Typeof (Requiredattribute ), Typeof (Requiredattributeadapter ));} Public  Override Ienumerable <modelclientvalidationrule> getclientvalidationrules (){ Return   New [] { New Modelclientvalidationrequiredrule (errormessage )};}}

Add a sentence to global. asax.

 
Requiredattributeadapter. selfregister ();
