What is routing in MVC?

Routing helps you to define a URL structure and map the URL with the controller.

For instance let’s say we want that when a user types “http://localhost/View/ViewCustomer/”, it goes to the “Customer” Controller and invokes the DisplayCustomer action. This is defined by adding an entry in to the routes collection using the MapRoute function. Below is the underlined code which shows how the URL structure and mapping with controller and action is defined.

routes.MapRoute(

               "View", // Route name

               "View/ViewCustomer/{id}", // URL with parameters

               new { controller = "Customer", action = "DisplayCustomer", 

               id = UrlParameter.Optional }); // Parameter defaults
