The variables during the route attribute is usually limited to a particular information form. This would be practical for your id. Ids usually are int, so it is smart to hope an int id.

The IUrlHelper interface is the fundamental ingredient of infrastructure concerning MVC and routing for URL technology. An occasion of IUrlHelper is offered with the Url assets in controllers, views, and consider elements.

This approach can boost the clarity and predictability with the URL composition, rendering it more straightforward for the two developers and customers to understand how routes map to controller actions.

You will note an HTTP 404, because the routing engine is seeking ProcessController, which is not obtainable.

The following example configures MVC to use the default conventional route and a region route for a region named Web site:

Nevertheless if we designed a MVC web site for the same, the URL would in all probability appear like ‘hxxp://’ and ‘hxxp://’. By convention (and default) the main URL maps for the ProductController course with an action named Index. The 2nd URL maps on the ProductController course with and action named Aspects. As we could see, MVC Routing aids abstract URLs from physical documents which by default maps to Controller/Action technique pairs by default. We'll now go into specifics of how this mapping comes about and how to modify the defaults. But right before that, some ideal practices!  

From the previous code, MapControllers is named inside UseEndpoints to map attribute routed controllers.

The GetIntProduct action has the "int/ id:int " template. The :int portion of the template constrains the id route values to strings which can be converted to an integer. A GET request to /api/test2/int/abc: Would not match this motion.

With attribute routing, the controller and action names Enjoy no section wherein motion is matched, Except if token routing in asp.net mvc alternative is utilised. The next example matches exactly the same URLs because the prior case in point:

Extracts the route values controller = Products and solutions, action = Particulars, id = five by tokenizing The trail. The extraction of route values brings about a match If your app includes a controller named ProductsController along with a Aspects motion:

To generate attribute routing fewer repetitive, route characteristics within the controller are coupled with route characteristics on the individual actions.

The previous example of Url.Motion assumes conventional routing. URL technology functions in the same way with attribute routing, while the concepts are various. With standard routing:

Simplicity: It minimizes the necessity to outline routes explicitly For each action technique or controller; as an alternative, it makes use of default conventions.

The namespace of each and every controller is revealed below for completeness. Should the preceding controllers utilised a similar namespace, a compiler error would be produced. Course namespaces don't have any effect on MVC's routing.
