问题 OK so here's the situation. I've got a classic ASP website running inside an MVC 4 application.

问题 Is this a bug or a feature? All code below has been simplified for the sake of brevity and easy replication and does not actually do anything useful other than highlight the behavior. I have a class that includes an int named ID: public class FooterLink { public int ID { get; set; } } In my controller, I have an Edit actionresult that takes a parameter called 'id': public ActionResult Edit(int id) { return View(new FooterLink() { ID = 5 }); //notice that I am explicitly setting the ID value

问题 I'm trying to write a MapRoute call that will make any route that is prefixed with "json/" prepend "json" to the action's name. For instance, a route something like this: "json/{controller}/{action}" with "json/Foo/Bar", it should result in: controller = "Foo" action = "jsonBar" Any ideas? 回答1: I wonder if it wouldn't be better to include json in the route-data and look it up in the action? i.e. when mapping your route, use something like (for the defaults): new { mode="json", controller =
