In this video we will discuss Attribute Routing introduced in ASP.NET Web API 2. Let us understand attribute routing with an example
What is Attribute Routing
Using the [Route] attribute to define routes is called Attribute Routing
What are the advantages of using Attribute Routing
Attribute routing gives us more control over the URIs than convention-based routing. Creating URI patterns like hierarchies of resources (For example, students have courses, Departments have employees) is very difficult with convention-based routing. With attribute routing all you have to do is use the [Route] attribute as shown below.
[Route(“api/students/{id}/courses”)]
How to enable Attribute Routing
In ASP.NET Web API 2, Attribute Routing is enabled by default. The following line of code in WebApiConfig.cs file enables Attribute Routing.
config.MapHttpAttributeRoutes();
Can we use both Attribute Routing and Convention-based routing in a single Web API project
Yes, both the routing mechanisms can be combined in a single Web API project. The controller action methods that have the [Route] attribute uses Attribute Routing, and the others without [Route] attribute uses Convention-based routing.
