How to avoid query string parameters in MVC

Question

I have the following route

routes.MapRoute("CreateBook", "{controller}/{action}/{slug}/{name}", new { controller = "CreateBook", action = "Index" , slug = UrlParameter.Optional, name = UrlParameter.Optional});

For some reason, whenever I call RedirectToAction, the URL appears as

return RedirectToAction("Parameters", new { slug=1234, name="helloworld" });

http://localhost/CreateBook/Parameters?slug=1234?name=helloworld

What I would like is

http://localhost/CreateBook/Parameters/1234/helloworld

How do I achieve this?

Answer 1

My guess is that the RedirectToAction call is picking up the default route, not your specialised route.

By default, when you pass in route values, MVC will append the values as querystring parameters.

Did you put that route before the default route?
