Display View in folder without Controller or Action in ASP.net MVC

Question

I would like to display the view in the folder if no controller/action matches.

For example www.site.com/Home/Index, if I have the normal default route {controller}/

For missing actions you can override HandleUnknownAction.

For missing controllers you can implement a custom DefaultControllerFactory and override GetControllerInstance with something like this:

protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) {

   if (controllerType == null)
      return new DumbController();

   return base.GetControllerInstance(requestContext, controllerType);
}

class DumbController : Controller {

   protected override void HandleUnknownAction(string actionName) {

      try {
         View(actionName).ExecuteResult(this.ControllerContext);
      } catch (Exception ex) {
         throw new HttpException(404, "Not Found", ex);
      }
   }
}
