Suppose your Net application is managing on then the url sample for your personal software will be controller / motion / id . Hence you should supply the controller title followed by the action name and ID if it is necessary.

If you want to prohibit the id parameter benefit being an integer only, then you might want to use an idea named Route Constraint in ASP.

Buy of Parameters: Optional parameters ought to be at the end of the route template. If an optional parameter precedes a expected parameter, the routing may become ambiguous and could not behave as envisioned.

If you won't supply any of the values then the default values of such parameters might be supplied by the routing system. Here's a list of URLs that match And do not match this route sample.

The primary two controllers are members of areas, and only match when their respective space name is supplied by the realm route worth. The 3rd controller is just not a member of any region, and can only match when no price for spot is furnished by routing.

I've produced a small application with an individual Entity identified as Product that has the following Qualities

Utilizing the preceding controller definition and route template, the HomeController.Index action is operate for the subsequent URL paths:

Now if we glance from the ProductController.cs, we will discover Action strategies for Get and Submit Http actions for every of the above mentioned views. This helps make the following default routes accessible

In such cases the default values are controller = Web site, motion = Article , and neither controller nor action seems as a route parameter.
