Redirection in ASP.NET MVC

Redirection in ASP.NET MVC:-

Using this we can redirect from one controller to another using the controller method,ASP.NET MVC provides three different types of ActionResult method for Redirection.

1)  Redirect()  :-

We can pass the complete URL under redirect(), we will use the web URL of the current application or cross-application using Redirect().

public ActionResult Methodname()
{
         return Redirect("url");
}

Example:-

 public class URLRedirectionController : Controller

    {

        //

        // GET: /URLRedirection/

        public ActionResult Index()

        {

           // return Redirect("http://shivatutorials.com");

            return Redirect("Home/Index");

        }

    }

2) RedirectToAction():-  

We can pass Action name and Controller name under RedirectToAction(). It will work using Single Parameters and Multiple Parameters.


public ActionResult Methodname()
{
     //    return RedirectToAction("Methodname");   //same controller
           return RedirectToAction("Methodname","Controllername");  // cross controller
}


Example of RedirectToAction:-

public class URLRedirectionController : Controller

    {

        //

        // GET: /URLRedirection/

        public ActionResult Index()

        {

           // return RedirectToAction("Index", "Home");

            return RedirectToAction("About");

        }

        public ActionResult About()

        {

            return View();

        }

    }

3)  RedirectToRoute() :-  

We can pass Actionname and Controllername using Routename by routeconfig.cs under RedirectToRoute(). It will work using route name ;


public ActionResult Methodname()
{
             return RedirectToRoute("Routername");
         

}

First Create Custom Route under routeconfig.cs file and custom route should be defined before of default routing path.

public class RouteConfig

    {

        public static void RegisterRoutes(RouteCollection routes)

        {

            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(

               name: "CustomRoute",

               url: "{controller}/{action}/{id}",

               defaults: new { controller = "URLRedirection", action = "About", id = UrlParameter.Optional }

           );

            routes.MapRoute(

                name: "Default",

                url: "{controller}/{action}/{id}",

                defaults: new { controller = "URLRedirection", action = "Index", id = UrlParameter.Optional }

            );

        }

    }

Create Controller and Write Following Code:-

public class URLRedirectionController : Controller

    {

        //

        // GET: /URLRedirection/

        public ActionResult Index()

        {

            return RedirectToRoute("CustomRoute");

        }

        public ActionResult About()

        {

            return View();

        }

    }
