چرا مسیریابی نشانه ای

routes.MapRoute(
    name: "ProductPage",
    url: "{productId}/{productTitle}",
    defaults: new { controller = "Products", action = "Show" },
    constraints: new { productId = "\\d+" }
);

[Route("{productId:int}/{productTitle}")]
public ActionResult Show(int productId) { ... }

فعال سازی Attribute Routing

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
 
        routes.MapMvcAttributeRoutes();
    }
}

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
 
    routes.MapMvcAttributeRoutes();
 
    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}

پارامترهای اختیاری URI و مقادیر پیش فرض

public class BooksController : Controller
{
    // eg: /books
    // eg: /books/1430210079
    [Route("books/{isbn?}")]
    public ActionResult View(string isbn)

        if (!String.IsNullOrEmpty(isbn))
        {
            return View("OneBook", GetBook(isbn));
        }
        return View("AllBooks", GetBooks());
    }
 
    // eg: /books/lang
    // eg: /books/lang/en
    // eg: /books/lang/he
    [Route("books/lang/{lang=en}")]
    public ActionResult ViewByLanguage(string lang)
    {
        return View("OneBook", GetBooksByLanguage(lang));
    }
}

پیشوند مسیرها (Route Prefixes)

public class ReviewsController : Controller
{
    // eg: /reviews
    [Route("reviews")]
    public ActionResult Index() { ... }
    // eg: /reviews/5
    [Route("reviews/{reviewId}")]

    // eg: /reviews/5/edit
    [Route("reviews/{reviewId}/edit")]
    public ActionResult Edit(int reviewId) { ... }

[RoutePrefix("reviews")]
public class ReviewsController : Controller

    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) { ... }
}

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

مسیر پیش فرض

[RoutePrefix("promotions")]
[Route("{action=index}")]
public class ReviewsController : Controller
{
    // eg.: /promotions
    public ActionResult Index() { ... }
 
    // eg.: /promotions/archive
    public ActionResult Archive() { ... }
 
    // eg.: /promotions/new
    public ActionResult New() { ... }
 
    // eg.: /promotions/edit/5
    [Route("edit/{promoId:int}")]
    public ActionResult Edit(int promoId) { ... }
}

محدودیت‌های مسیر ها

// eg: /users/5
[Route("users/{id:int}"]
public ActionResult GetUserById(int id) { ... }
 
// eg: users/ken
[Route("users/{name}"]
public ActionResult GetUserByName(string name) { ... }
