How to get RouteCollection from a request in ASP.NET MVC 4

Question

This is my global.asax (Registering the route)

  routes.MapRoute("NewDatabase",
             "Server/{serverId}/Instances/{instanceId}/NewDatabase/",
             new { controller = "Server", action = "NewDatabase" }
             );

            routes.MapRoute(
           "Instance",
           "Server/{id}/Instances/{instanceId}/Databases",
           new { controller = "Server", action = "Databases", id = "id",instanceId="instanceId" }
           );

            routes.MapRoute(
           "Database",
           "Server/{id}/Instances",
           new { controller = "Server", action = "Instances", id = "id" }
           );

If xyz.com/Server/12/Instance/1/NewDatabase will be the reuested URL to server, Server/{serverId}/Instances/{instanceId}/NewDatabase/ will be the matching pattern. How can I know which entry is matched for the above request ?

Thanks

Answer 1

RouteTable.Routes.GetRouteData(HttpContextBase)

Install the RouteDebugger nuget package and enabled it in your web.config. This tells you which routes can be hit and why.

<add key="RouteDebugger:Enabled" value="true" />

All you have to do is navigate to your url. RouteDebugger will add route info to the bottom of your page.

I am not sure if this is what you are looking for but you can create a custom route constraint which enables you to prevent a route from being matched unless some custom condition is matched.

You can implement Match method which returns a Boolean value. If you return false, the route associated with the constraint won't match the browser request. This method has RouteValueDictionary so you can check route values from there.
