How to bind response to GridView using C# in ASP.Net

i run the debug mode and it does not go in for loop

for int count comes in = 0

then it does not go in for each loop

its strange if it is working with you then why it is not working with me

for (int i = 1; i < obj.Count; i++)
            {
                results.Add(((Newtonsoft.Json.Linq.JObject)(((Newtonsoft.Json.Linq.JContainer)((obj["result"]))))).ToString());
            }
            List<Results> mapList = new List<Results>();
            foreach (string item in results)
            {
                Results root = JsonConvert.DeserializeObject<Results>(item);
                Results map = new Results()
                {
                    PostCode = root.PostCode,
                    Latitude = root.Latitude,
                    Longitude = root.Longitude
                };
                mapList.Add(map);
               
            }
