asp.net mvc 2 - Trouble Figuring Out The routes.Maproute For This URL (C#) -

despite plethora of url routing posts, have yet reach enlightenment on subject.

i have mvc app works fine, want fancy , url rewriting make easier on users.

the default route slight variation on usual:

routes.maproute(       "default",       "{controller}/{action}/{query}",       new{ controller = "somecontroller", action="index", query = "" }); 

what want re-route url http://mysite.com/12345 details action of somecontroller 12345 query. tried this:

routes.maproute(       "directtodetails",       "{query}",       new{ controller = "somecontroller", action="details" query="" });  routes.maproute(       "default",       "{controller}/{action}/{query}",       new{ controller = "somecontroller", action="index", query = "" }); 

but ends obscuring http://mysite.com/ , goes somecontroller/details instead of somecontroller/index.

edit:

per advice of @jon removed query = "" in anonymous object:

routes.maproute(       "directtodetails",       "{query}",       new{ controller = "somecontroller", action="details" }); 

... addressed question far went; when submit form @ views/someview/index (that submits aforementioned somecontroller/details) "resource cannot found" error.

here form declaration:

<% using (html.beginform(               "details",                "somecontroller",                formmethod.post,                new { id = "searchform" })) { %>     <% html.renderpartial("searchform", model); %>     <%= html.validationmessagefor(model => model.query) %> <% } %> 

remove query = "" (obviously it's not optional because of problem you're having - no need put in 3rd argument if there's no sensible default) , use overload of maproute takes 4th parameter route constraints:

routes.maproute(   "directtodetails",   "{query}",   new { controller = "somecontroller", action="details" },   new { query = @"\d+" }); 

obviously need adjust regex if it's not integer...

in response edit...make sure you've removed default query "short" route - you've posted default 1 there. suggest double check form , make sure it's posting value query (maybe set break point on post action method , make sure query parameter being bound correctly?).
