Routing with Multiple Parameters using ASP.NET MVC

by

Parameters are directly supported in MVC by simply adding parameters onto your action methods. Given an action like the following:

public ActionResult GetImages(string artistName, string apiKey)

MVC will auto-populate the parameters when given a URL like: 

/Artist/GetImages/?artistName=cher&apiKey=XXX

One additional special case is parameters named “id”. Any parameter named ID can be put into the path rather than the querystring, so something like:

public ActionResult GetImages(string id, string apiKey)

would be populated correctly with a URL like the following:

/Artist/GetImages/cher?apiKey=XXX

In addition, if you have more complicated scenarios, you can customize the routing rules that MVC uses to locate an action. Your global.asax file contains routing rules that can be customized. By default the rule looks like this:

routes.MapRoute(
            "Default",                                              // Route name
            "{controller}/{action}/{id}",                           // URL with parameters
            new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
        );

If you wanted to support a url like 

/Artist/GetImages/cher/api-key

you could add a route like:

routes.MapRoute(
            "ArtistImages",                                              // Route name
            "{controller}/{action}/{artistName}/{apikey}",                           // URL with parameters
            new { controller = "Home", action = "Index", artistName = "", apikey = "" }  // Parameter defaults
        );

and a method like the first example above.
