Core code

 

Public class AreaDomainRegistrationContext {// <summary> ///// </summary> // <param name = "_ domainName"> subdomain names such: you can upload abc </param> public AreaDomainRegistrationContext (AreaRegistrationContext _ context, string _ domainName) {domainName = _ domainName; context = _ context;} private string domainName; private AreaRegistrationContext context; private RouteCollection Routes {get {if (!

Call Code

// Global. asax. put cs Application_Start at the beginning of RouteTable. routes. add (new DomainRoute (); ResolveDomainName. domainMap. add ("demo.abc.com: 8098", "demo"); // public class demoAreaRegistration: AreaRegistration {public override string AreaName {get {return "demo ";}} public override void RegisterArea (AreaRegistrationContext context) {context. mapRoute (name: "demo_default", url: "demo/{controller}/{action}", defaults: new {controller = "index", action = "index "}, namespaces: new string [] {"xxx. xxx "}); var context2 = new AreaDomainRegistrationContext (context," demo "); context2.MapRoute (name:" demo_default ", url:" {controller}/{action} ", ults: new {controller = "index", action = "index"}, namespaces: new string [] {"xxx. xxx "});}}

The view uses bool B = (string) ViewContext. RouteData. DataTokens ["SubDomain"]! = Null; you can determine whether the request is accessed using the demo.abc.com domain name.

Use http://demo.abc.com: 8098/and http: // localhost: 8098/demo to access Area demo
