REST APIs should use attribute routing to product the app's functionality as a list of assets in which operations are represented by HTTP verbs.

We could also constrain the routes by specifying the Standard Expression for controller, action approach etcetera.

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

If there are optional parameters then parameters coming after the optional param must be named inside the Url with the routing to work effectively. So We've now observed what the default ASP.Internet route implies And just how we will leverage routes in MVC for making discoverable URLs that respond to improvements within the URL by presenting context conscious knowledge. To round off, we see how we can easily make use of the Routing mechanism to make URLs for us as I mentioned above. Making use of MVC Routing to Generate URLs

Right here, “id:int?” states that id is surely an optional parameter, but for those who move any value, it should be of form integer. It is possible to determine only one optional parameter for every route, which should be the final parameter.

We can even constrain the route applying its worth constraint.

Conventional routing only matches a mix of motion and controller which can be outlined because of the app. This is intended to simplify situations the place traditional routes overlap.

To attain this, we are able to configure One more MapControllerRoute strategy, as revealed during the below picture. In this routing in asp.net mvc article, you are able to see We have now specified the pattern as StudentDetails/ ID and specified the default controller and motion identify as controller = University student”, action = Particulars.

This is called Inline Route Constraint. Inline constraints are specified instantly throughout the route template by appending a colon (:) followed by the constraint name to a route parameter.

Utilizing standard routing Together with the default route makes it possible for developing the application without needing to come up with a fresh URL sample for each motion. For an application with CRUD model actions, possessing consistency for the URLs throughout controllers:
