How to Configure Routing in MVC:

0). Route must be registered in Application_Start event in Global.ascx.cs file.
1). Routing plays important role in MVC framework. Routing maps URL to physical file or class.
2). Route contains URL pattern and handler information. URL pattern starts after domain name.
3). Routes can be configured in RouteConfig class. Multiple custom routes can also be configured.

--------------------------------------------------------------------------------------
Below Example:-

public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}

URL Controller Action Id
http://localhost/home Home Index Null
http://localhost/home/index/786 Home Index 786
