Question

iam having controller like below which is not registered in routes table

public class InternalController : Controller
{
 /*this controller is not registered in routes table*/ 

      public ActionResult Foo()
      {
         return Content("Text from foo");
      }
}

From another controller which is registered in Routes table i want to call/redirect action of previous controller, one which is not registered in routes table.

public class AjaxController : Controller
{
 /*this controller is registered in routes table*/  

      public ActionResult Foo()
      {

           /*FROM HERE HOW DO I RETURN CONTENTS OF  
            controller=InternalController, action = Foo
           */

            /*
              i tried below piece of code but that doesnt seem to work
            */

            return RedirectToAction("Foo", "InternalController ");
      } 
}

Defined Routes (only one item added)

    public void RegisterRoutes(RouteCollection routes)
    {
       routes.MapRoute("Ajax","ajax/{action}",new {
       controller="Ajax",
       action="Index"
       });
   }

Answer 1

Now that you have shown your routes definition, it is obvious that you can never invoke any other controller than AjaxController. You simply forbid them in your routes, so InternalController could never be served. You will have to change your route definition.

Depending on what you want to achieve and how you want your urls to look like you have a couple of possibilities:

• Leave the default route

• Modify your existing route definition like so:

  routes.MapRoute(
      "Ajax",
      "{controller}/{action}",
      new { controller = "Ajax", action = "Index" }
  );
