I'm not getting friendly url in a form with GET method

Question

I setup a route like that:

routes.MapRoute(
    name: "Pesquisar",
    url: "Pesquisar/{aaa}/{bbb}/{id}",
    defaults: new { controller = "Home", action = "Pesquisar",
                    aaa = UrlParameter.Optional,
                    bbb = UrlParameter.Optional,
                    id = UrlParameter.Optional
    }
);

When I press Send button in a form (with GET method) the url is like that:

http://localhost:00000/Pesquisar?aaa=One&bbb=Two

But I was expecting for:

http://localhost:00000/Pesquisar/One/Two

When you map a rout, it adds it to the end of a list. When the router looks for the rule to match, it starts at the begining of the list and itterates through it. It will take the first rule that matches, not the most specific rule. Because it is natural to append code to the end, the default rule (which works for almost everything) will be at the start.

Try re-ordering your code to look like this:

        ///The specific rout which you want to use
        routes.MapRoute(
        name: "Pesquisar",
        url: "{action}/{aaa}/{bbb}/{id}",
        defaults: new { controller = "Home", action = "Pesquisar",
                        aaa = UrlParameter.Optional,
                        bbb = UrlParameter.Optional,
                        id = UrlParameter.Optional
        }
        );

        ///The generic catch all router
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
