NameSpace

using Newtonsoft.Json;

Code

protected void Page_Load(object sender, EventArgs e)
{
    string page = "https://api.postcodes.io/postcodes/L33AN";
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(page);
    //&tracking_number=" + txtttnumber.Text + "&courier=" + ddlcourier.SelectedValue
    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    if (response.StatusCode == HttpStatusCode.OK)
    {
        Stream receiveStream = response.GetResponseStream();
        StreamReader readStream = null;
        if (response.CharacterSet == null)
            readStream = new StreamReader(receiveStream);
        else
            readStream = new StreamReader(receiveStream, Encoding.GetEncoding(response.CharacterSet));
        string data = readStream.ReadToEnd();
        dynamic obj = JsonConvert.DeserializeObject(data);
        List<string> results = new List<string>();
        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);
        }

        GridView1.DataSource = mapList;
        GridView1.DataBind();
    }
}

public class Results
{
    public string PostCode { get; set; }
    public string Longitude { get; set; }
    public string Latitude { get; set; }
}

HTML

<asp:GridView runat="server" ID="GridView1">
</asp:GridView>

Output

the problem i on obj.count loop on loop it takes obj.count = 0 therefore it is going inside the loop
