            req.Timeout = 60000;
            HttpWebResponse resp = (HttpWebResponse)req.GetResponse();

            StreamReader sr = new StreamReader(resp.GetResponseStream());
            string results = sr.ReadToEnd();
            sr.Close();

            return results;
        }

    }

var result = new Request().requestFBData("https://graph.facebook.com/platform/statuses?access_token=" + "202929493078068|886e4149cac7be0fc12e2d4b.0-100002424609963|a9CMw51PYEW3kj4xw77JyEJoRrI");
    var deserializedAllStatus = javaScriptSerializer.Deserialize<Allstatus>(result);
    foreach (sdata sd in deserializedAllStatus.data)
        foreach (likesdata ld in sd.likes.data)
            Console.WriteLine(ld.id + ld.name);

Could you also show what the variable result contains? What is the actual json returned by the server? Please replace any sensitive/personal info with dummy info.

the key is dummy.. i will delete it anyway soon. The returned info is from https://graph.facebook.com/platform/statuses?access_token=< access_token here > This brings a nullreference on the likesdata. I don't know every thing from code looks okay.

I have tried both using system.web.script.serialization and using JSON.net. Both bring null reference.. After initializing the likesdata using contructors.

Adding a constructor in the sdata.. solved it..
