The URL gets very simple, ASP. NET generic:
"1" get the full URL
(Protocol name + domain + virtual directory name + file name + parameter)

String url=request.url.tostring ();

"2" gets the virtual directory name + page name + parameters:

String Url=request.rawurl;
(or string
Url=request.url.pathandquery;)

"3" get
Virtual directory name + page name:
String Url=httpcontext.current.request.url.absolutepath;
(or
String url= HttpContext.Current.Request.Path;)

"4" gets the domain name:
String
Url=httpcontext.current.request.url.host;

"5" gets the parameter:
String url=
HttpContext.Current.Request.Url.Query;

"6" Gets the port:
Request.Url.Port

Ii. acquisition of the current Controller and action
RouteData.Route.GetRouteData (this. HttpContext). values["Controller"]
RouteData.Route.GetRouteData (this. HttpContext). Values["Action"]
or
routedata.values["Controller"]
routedata.values["Action"]

If you can use it in the view
ViewContext.RouteData.Route.GetRouteData (this. Context). values["Controller"]
ViewContext.RouteData.Route.GetRouteData (this. Context). Values["Action"]
or
viewcontext.routedata.values["Controller"]
viewcontext.routedata.values["Action"]
