c# read json from httpWebResponse

Question

I'm getting a json from httpWebResponse which supposed to be in the following format :

{"d":"{\"Success\":\"\",\"PricedItineraries\":[{\"IsRecommendedFlight\":false,\"BookingClass\":null,\"AirItinerary\":{\"OriginDestinationOptions\":{\"OriginDestinationOption\":[{\"FlightSegment\":[{\"DepartureAirport\":{\"LocationCode\":\"RAK\",\"Terminal\":\"1\"},\"ArrivalAirport\":{\"LocationCode\":\"ORY\",\"Terminal\":\"S\"},\"Equipment\":{\"AirEquipType\":\"73H\",\"ChangeofGauge\":\"true\"},\"MarketingAirline\":{\"Code\":\"TO\",\"CodeContext\":\"KBATO\"},\"OperatingAirline\":{\"Code\":\"TO\"},\"BookingClassAvails\":[{\"ResBookDesigCode\":\"A\",\"RPH\":\"5\"}],\"BagAllownceInfo\":{\"Allowance\":\"00\",\"QuantityCode\":\" N\",\"UnitQualifier\":\" K\"},\"FareID\":\"000000000\",\"Token\":\"00000000-0000-0000-0000-000000000000\",\"AdultBaseFare\":\"0000517.77\",\"AdultTaxFare\":\"0000000.00\",\"ChildBaseFare\":\"0000000.00\",\"ChildTaxFare\":\"0000000.00\",\"InfantBaseFare\":\"0000000.00\",\"InfantTaxFare\":\"0000000.00\",\"PriceTotal\":\"0000307.90\",\"LFID\":\"0000000\",\"PFID\":\"00000\",\"PTFID\":\"

I tried to Deserialize the json using JSonConverter but it returns stream was not readable:

public static object DeserializeFromStream(Stream stream)
{
    var serializer = new JsonSerializer();

    using (var sr = new StreamReader(stream))
    using (var jsonTextReader = new JsonTextReader(sr))
    {
        return serializer.Deserialize(jsonTextReader);
    }
}

So I'm reading my httpwebresponse:

using (StreamReader Reader = new StreamReader(ResStream))
{
    this.ResponseHTML = Reader.ReadToEnd();
}

But somehow it returns:

I'm sending the webrequest :

 public Response Send()
        {
            if (REQUEST == null)
                return new Response(REQUEST) { HTTPStatusCode = "999" }; 

            WebResponse Res = null;
            CookieContainer Cookies = new CookieContainer();
            if (REQUEST.Cookies != null)
            {
                Cookies = REQUEST.Cookies;
            }
            bool isdone = true;
            DateTime Time = default(DateTime);
            Sender = (HttpWebRequest)WebRequest.Create(this.REQUEST._url);
            Sender.Host = REQUEST.Host;
            Sender.Accept = REQUEST.Accept;
            Sender.Method = REQUEST.Method;
            Sender.UserAgent = REQUEST.UserAgent;
            Sender.ContentType = REQUEST.ContentType;
            Sender.CookieContainer = Cookies;
            Sender.Referer = REQUEST.Refer;

            if (REQUEST.Data != null && REQUEST.Data.Length > 0)
            {
                using (var writer = new StreamWriter(Sender.GetRequestStream()))
                {
                    writer.Write(REQUEST.Data);
                    writer.Flush();
                    writer.Close();
                }
            }

            try
            {
                Res = Sender.GetResponse();
                Time = DateTime.Now;
            }
            catch (Exception Ex)
            {
                isdone = false;
                if (OnExceptionHappened != null)
                    OnExceptionHappened(this, new ExceptionArgs { Msg = Ex.Message, Sender = this, Time = DateTime.Now });
            }

            return AssignWebResponse((HttpWebResponse)Res, isdone, Time, Cookies, Sender.RequestUri.AbsoluteUri);
        }

Request :

        var REQUEST = new Request()
        {
            _url = "https://www.example.com/",
            Host = "host",
            Method = "POST",
            Refer = "refer",
            UserAgent = "Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0",
            ContentType = "application/json",
            Cookies = CurrentContainer,
            Data = "{ 'isFromCache': 'undefined', 'pageNumber': '1'}",
            isJson = true
        };
        using (BeRequest.CORE.BeRequest Req = new BeRequest.CORE.BeRequest(REQUEST))
        {
            Req.OnExceptionHappened += Req_OnExceptionHappened;
            var response = Req.Send();

            return response.ResponseHTML;
        }

Answer 1

Just do:

using (StreamReader Reader = new StreamReader(Res.GetResponseStream()))
{
    var myObject = JsonConvert.DeserializeObject<YourClass>(Reader.ReadToEnd());
}

Your code is a bit all over the place. But assuming that Res is of type WebResponse, then it should work.
