Asp.net Mvc dynamically creates Controller and mvccontroller

Urls has the following requirements:

Http: // localhost: 52804

Http: // localhost: 52804/home/test

Http: // localhost: 52804/test1

Http: // localhost: 52804/test1/aaa

Http: // localhost: 52804/test1/bbb

Http: /localhost: 52804/test2/aaa

Http: // localhost: 52804/test2/bbb

The 1st and 2 URLs represent the real existence of the Controller, and the latter all need to dynamically generate the Controller. To achieve this requirement, you can rewrite the defacontrocontrollerfactory implementation by searching for information. The steps and Code are as follows:

1. New FolderControllerFactory. cs inherits from DefaultControllerFactory

Public class FolderControllerFactory: DefaultControllerFactory {public override IController CreateController (RequestContext requestContext, string controllerName) {var controllerType = GetControllerType (requestContext, controllerName); // if the controller does not exist, replace with FolderController if (controllerType = null) {// use the routing field to dynamically build the routing variable var dynamicRoute = string. join ("/", requestContext. routeData. values. values); controllerName = "Folder"; controllerType = GetControllerType (requestContext, controllerName); requestContext. routeData. values ["Controller"] = controllerName; requestContext. routeData. values ["action"] = "Index"; requestContext. routeData. values ["dynamicRoute"] = dynamicRoute;} IController controller = GetControllerInstance (requestContext, controllerType); return controller ;}}

2. Create a FolderController

public class FolderController : Controller    {        // GET: Folder        public ActionResult Index(string dynamicRoute)        {                        string viewFile = "/Views/" + dynamicRoute + ".cshtml";            return View(viewFile);        }    }

3. Modify routing rules

 public static void RegisterRoutes(RouteCollection routes)        {            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");            routes.MapRoute(                name: "Default",                url: "{controller}/{action}/{id}",                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }            );            routes.MapRoute(                "CatchAll",                "{*dynamicRoute}",                new { controller = "Folder", action = "Index" }            );        }

4. register the custom FolderControllerFactory at Global. asax.

protected void Application_Start()        {            ControllerBuilder.Current.SetControllerFactory(new FolderControllerFactory());            AreaRegistration.RegisterAllAreas();                        RouteConfig.RegisterRoutes(RouteTable.Routes);        }

5. Create some folders and Views under Views for testing,

 

The test results are as follows:

 

In this way, the needs of bloggers are simply realized ..
