Routing in MVC

Routing in MVC

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

The route mapping code is written in the “global.asax” file.

For Example

routes.MapRoute(
               "View", // Route name
               "View/ViewCustomer/{id}", // URL with parameters
               new { controller = "Customer", action = "DisplayCustomer",

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

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.

Note:
We can map multiple URL'S to the same action.
Add two entries with different key names and specify the same controller and action.
