asp.net mvc 4 - ASP:NET MVC4 url routing for controllers with the same name in different namespaces -

in asp.net mvc4 web project, have many controllers , want put them subdirectories under folder "controllers". controllers have same name due major jobs, put under different subdirectories, means different namespaces. want url routing controllers. how can make routing consider namespaces controllers same name exist? show code how in global.asax file?
lot.

you need several maproute-s - @ lease 1 each namespace.

 // match controllers in first namespace  routes.maproute(     name: "namespace1routes",     url: "path1/{controller}/{action}/{id}",     defaults: new { controller = "home", action = "index", id = urlparameter.optional },     namespaces: new[] { "my.namespace1" }  );   // match controllers in second , third namespaces  routes.maproute(     name: "namespace2routes",     url: "path2/{controller}/{action}/{id}",     defaults: new { controller = "home", action = "index", id = urlparameter.optional },     namespaces: new[] { "my.namespace2", "my.namespace3" }  );
