asp.net-mvc-5 Attribute routing in mvc-5 Route Prefixes

Example

Often, the routes in a controller all start with the same prefix. For example:

public class ReviewsController : Controller
{
    // eg: /reviews
    [Route(“reviews”)]
    public ActionResult Index() { … }
    // eg: /reviews/5
    [Route(“reviews/{reviewId}”)]
    public ActionResult Show(int reviewId) { … }
    // eg: /reviews/5/edit
    [Route(“reviews/{reviewId}/edit”)]
    public ActionResult Edit(int reviewId) { … }
}

You can set a common prefix for an entire controller by using the [RoutePrefix] attribute:

[RoutePrefix(“reviews”)]
public class ReviewsController : Controller
{
    // eg.: /reviews
    [Route]
    public ActionResult Index() { … }
    // eg.: /reviews/5
    [Route(“{reviewId}”)]
    public ActionResult Show(int reviewId) { … }
    // eg.: /reviews/5/edit
    [Route(“{reviewId}/edit”)]
    public ActionResult Edit(int reviewId) { … }
}

Use a tilde (~) on the method attribute to override the route prefix if needed:

[RoutePrefix(“reviews”)]
public class ReviewsController : Controller
{
    // eg.: /spotlight-review
    [Route(“~/spotlight-review”)]
    public ActionResult ShowSpotlight() { … }
 
    …
}
