Hi, i`m trying to read a facebook wall using Json, but I get the error-
Cannot access child value on Newtonsoft.Json.Linq.JProperty. Any ideas?

string pageInfo = client.DownloadString(string.Format("https://graph.facebook.com/Pokerfreerollpass?access_token={0} ", accessToken));
           string pagePosts = client.DownloadString(string.Format("https://graph.facebook.com/Pokerfreerollpass/posts?access_token={0} ", accessToken));
           //Console.Write(pagePosts);
           var result = JsonConvert.DeserializeObject<dynamic>(pagePosts);
           foreach (var item in result)
           {
               Console.WriteLine(item["body"]["message"].ToString());
           }
