asp.net web api - How to loop through all register api routes? -

i have function:

 protected void application_start()     {         database.setinitializer(new persondbinitializer());          globalconfiguration.configure(webapiconfig.register);          routeconfig.registerroutes(routetable.routes);     } 

the webapiconfig is:

public static class webapiconfig {     public static void register(httpconfiguration config)     {         // web api configuration , services          // web api routes         config.maphttpattributeroutes();          config.routes.maphttproute(             name: "defaultapi",             routetemplate: "api/{controller}/{id}",              defaults: new { id = routeparameter.optional }         );     } }

globalconfiguration.configuration.routes   foreach (system.web.http.routing.ihttproute route in globalconfiguration.configuration.routes) { }
