Alternate strategy to match attribute route in HyprLinkr Dispatcher

gistfile1.cs

 public Rouple Dispatch(MethodCallExpression method, IDictionary<string, object> routeValues)
        {
            if (method == null)
                throw new ArgumentNullException("method");

            var newRouteValues = new Dictionary<string, object>(routeValues);

            var controllerName = method
                .Object
                .Type
                .Name
                .ToLowerInvariant()
                .Replace("controller", "");
            newRouteValues["controller"] = controllerName;

            var attributeRoute = method.Method.GetCustomAttributes(true).Cast<HttpRouteAttribute>().FirstOrDefault();

            string routeName = null;

            if (attributeRoute != null)
            {
                var matchedRoute = _httpRequestMessage.GetConfiguration()
                                                      .Routes
                                                      .FirstOrDefault(x => 
                                                          (MethodInfo) x.DataTokens["actionMethod"] == method.Method) 
                                                      as HttpAttributeRoute;
                if (matchedRoute != null) routeName = matchedRoute.RouteName;
            }

            return new Rouple(routeName, newRouteValues);
        }
