[ASP.NET] MVC - Default action for no-matched actions in controller

 ASP.NET    MVC    action  

▌Introduction

---

Here is an example of catching non-matched Action in Controller, and then redirect to another Action (which is already implemented).

▌Environment

---

▋MVC 5.2.3

▌Implement

---

▋MVC : Controller

public class TestController : Controller {         public ActionResult Index(string actionName)         {             var viewModel = this.getViewModel(actionName);             if(viewModel!=null)                 return View(viewModel);             else                 throw new HttpException(404, "Page Not Found");         }         /// <summary>         /// Not matche actions will come here         /// </summary>         /// <param name="actionName"></param>         protected override void HandleUnknownAction(string actionName)         {             RedirectToAction("Index", new { actionName = actionName }).ExecuteResult(this.ControllerContext);         } }

▋Result

When I browse the following uri:

/Test/NonImplementedAction

We will be redirected to

/Test?actionName= NonImplementedAction

Which equals to /Test/Index?actionName= NonImplementedAction
