How to make routelink return the correct URL?

Question

here is the procedure to duplicate the issue.

1. start new mvc 4 project.

2. add the following lines to the RegisterRoutes() method just before the "Default" route

   routes.MapRoute(
           name: "Test",
           url: "Test/{action}",
           defaults: new { controller = "Test", action = "Index" }
   );
   

3. add the following to Index.cshtml and About.cshtml

   @Html.RouteLink("link to TestController", "Test")
   

As you can see that the generated html code is different for the 2 pages. I would expect the URL is "/Test" which is rendered correctly for Index.cshtml, but it become "/Test/About" for About.cshtml.

My question is if there is any documented way to generate the same correct URL. The above example is created just for demonstration purpose. I would like to use the routing table information to generate menu.

Answer 1

It seems the engine is setting the action route value from the current page ("Index", "About"). So one way to fix this is to "unset" that route value:

@Html.RouteLink("link to Test Controller", "Test", new { action = String.Empty })
