Any route templates outlined on the controller are prepended to route templates to the actions. Positioning a route attribute within the controller makes all actions in the controller use attribute routing.
The subsequent code helps prevent the namespace convention from staying placed on controllers which can be attribute routed:
This is because we haven't set any default values for our Route parameters. If we haven't specified the title of the controller or action method in the URL, which controller and action system really should execute?
This instance highlights a crucial programming distinction between attribute routing and standard routing. Attribute routing requires far more input to specify a route.
Attribute routes assist exactly the same inline syntax as regular routes to specify optional parameters, default values, and constraints.
Currently our Index web page only shows backlinks for Edit, Information and Delete. Nonetheless we could transform the Classification and Identify column to own one-way links that route MVC to drag up the index web page with the chosen group and name. Inside the routing in asp.net mvc Index.cshtml, we change the Razor markup as demonstrated below to generate the website link
Any time a ask for arrives, the UseRouting middleware parses the URL and matches it versus the outlined route templates saved during the route table.
Utilizing parts enables an app to have several controllers with the very same identify, so long as they have got different regions. Applying locations generates a hierarchy for the goal of routing by adding An additional route parameter, spot to controller and motion.
Where the distinctive title is described for this type of url pattern and if no price is laid out in the asked for url for controller, motion and id, the default value comes as Residence, Index (id remaining an optional, It isn't necessary to specify while in the url).
Additionally, to generating routes it can be done to enhance controller and actions with route characteristics.
To generate attribute routing a lot less repetitive, route attributes on the controller are coupled with route characteristics on the person steps.
Here, the id parameter will not be optional; it truly is mandatory, and though accessing any motion approach, it is actually obligatory to pass the Id parameter value.
Token substitute occurs as the final step of building the attribute routes. The preceding instance behaves similar to the following code:
