Question

I have set up an ASP.NET MVC project, and everything is working great, but I do have one problem with the routing. My Global.asax looks like this:

public static void RegisterRoutes(RouteCollection routes) {         routes.IgnoreRoute('{resource}.axd/{*pathInfo}');          routes.MapRoute(             'Default',                                              // Route name             '{controller}/{action}/{id}',                           // URL with parameters             new { controller = 'Home', action = 'Index', id = '' }  // Parameter defaults         );     } 

So, nothing out of the ordinary. My problem is that when I link to a controller/action/params with an HTML.ActionLink like so:

<%= Html.ActionLink('My link', 'SomeAction', 'SomeController', new {param='someParam'})%> 

it should generate (at least what makes sense in my head) a link such as: http://www.localhost/SomeController/SomeAction/someParam.

But instead it generates a link like this: http://localhost/SomeController/SomeAction?param=someParam

If i manually make a link that links to the expected result (SomeController/SomeAction/someParam) then the right controller and action are called, but the parameter defined in the action method is always null.

Any ideas?

I think that link will only use the default route like you expect if the parameter name is id instead of param. You’ll have to create a different route if you want to provide some other parameter there.
