How do I get the Controller and Action names from the Referrer Uri?

Question

There\'s a lot of information for building Uris from Controller and Action names, but how can I do this the other way around?

Basically, all I\'m trying to achieve i

Answer 1

Here is a lightweight way to do this without creating response objects.

var values = RouteDataContext.RouteValuesFromUri(Request.UrlReferrer);

var controllerName = values["controller"];
var actionName = values["action"];

Uses this custom HttpContextBase class

public class RouteDataContext : HttpContextBase {
    public override HttpRequestBase Request { get; }

    private RouteDataContext(Uri uri) {
        var url = uri.GetLeftPart(UriPartial.Path);
        var qs = uri.GetComponents(UriComponents.Query,UriFormat.UriEscaped);

        Request = new HttpRequestWrapper(new HttpRequest(null,url,qs));
    }

    public static RouteValueDictionary RouteValuesFromUri(Uri uri) {
        return RouteTable.Routes.GetRouteData(new RouteDataContext(uri)).Values;
    }
}
