To create attribute routing fewer repetitive, route attributes to the controller are coupled with route attributes on the individual actions.
It's important to grasp the job of characteristics like HttpPostAttribute. Comparable attributes are defined for other HTTP verbs.
Implement IRouteTemplateProvider to determine personalized route attributes. Just about every IRouteTemplateProvider lets you define only one route using a custom route template, purchase, and identify:
Attribute-dependent routing in ASP.Internet Main MVC makes it possible for developers to define routing immediately on controller actions or in the controller level applying attributes (decorators). This strategy offers much more control and adaptability about how URLs are mapped to steps in contrast to conventional routing, where by routes are configured globally in This system.
You'll be able to register a route in the RegisterRoutes method of RouteConfig course, which you'll find Along with the RouteConfig.cs class file beneath the App_Start folder. You will find the next code from the RouteConfig course.
Now, the problem That ought to arrive at your thoughts is, we have not explicitly described any routing regulations for our application. Then how is this mapping performed, i.e., how is the /Home/Index URL mapped for the Index action technique, and how will be the /Property/Facts/two URL mapped to the main points action method of the Home Controller class?
Given that an attribute route relates to a specific action, It is simple to help make parameters expected as part of the route template definition. In the next illustration, id is necessary as A part of the URL path:
Action 5 − Change the return variety from ActionResult to string in addition to return some string from this action technique employing the subsequent code.
In standard routing, It's normal for actions to work with exactly the same action title whenever they're Section of a display form, post sort workflow. Such as, see Analyze The 2 Edit action strategies.
HomeController matches a set of URLs comparable to exactly what the default traditional route controller=House / motion=Index / id? matches.
With this particular, we arrive at an in depth of this put up. We checked out the fundamentals of MVC routing and understood just what the default routing indicates. We also took a evaluate several samples of how routing assists make URLs discoverable And just how parameters can be passed making use of thoroughly clean URLs. To conclude, MVCs routing implementation frees up URLs from physical Affiliation to a file Hence opening up loads of adaptability with how URLs is often presented and interpreted within an MVC software.
A number of regular routes is often configured by incorporating additional phone calls to MapControllerRoute and MapAreaControllerRoute. Doing so permits defining several conventions, or to routing in asp.net mvc including standard routes which can be focused on a specific motion, for instance:
C# and .NET have been around for a very very long time, but their regular progress usually means there’s often extra to understand.
The namespace of every controller is demonstrated below for completeness. Should the previous controllers made use of the same namespace, a compiler mistake would be created. Course namespaces haven't any impact on MVC's routing.
