String URL to RouteValueDictionary

Question

Is there as easy way to convert string URL to RouteValueDictionary collection? Some method like UrlToRouteValueDictionary(string url).

I need such metho

I wouldn't rely on RouteTable.Routes.GetRouteData from previous examples because in that case you risk missing some values (for example if your query string parameters don't fully fit any of registered mapping routes). Also, my version doesn't require mocking a bunch of request/response/context objects.

public static RouteValueDictionary UrlToRouteValueDictionary(string url)
{
    int queryPos = url.IndexOf('?');

    if (queryPos != -1)
    {
        string queryString = url.Substring(queryPos + 1);
        var valuesCollection = HttpUtility.ParseQueryString(queryString);
        return new RouteValueDictionary(valuesCollection.AllKeys.ToDictionary(k => k, k => (object)valuesCollection[k]));
    }

    return new RouteValueDictionary();
}
