Data from GetResponseStream

Question

How can I get the sub_category_en on this data I receive from HttpWebRequest? I just want the two to three fields on the data received.

I used xamarin in visual studio 2013.. Thanks for helping. If using this Newtonsoft.Json.JsonSerializer is the ey on my problem. Can I have a small sample code? thanks

You can use JsonConvert.Deserialize to convert json to a custom object.

public class RootObject
{
    public int id { get; set; }
    public string sub_category_name { get; set; }
    public int child_level { get; set; }
    public int has_child { get; set; }
    public string sub_parent_url { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
      WebRequest objRequest = HttpWebRequest.Create(dest);
      WebResponse objResponse = objRequest.GetResponse();
      using (StreamReader reader = new StreamReader(objResponse.GetResponseStream()))
      {
        string jsonString = reader.ReadToEnd();

        var data = JsonConvert.DeserializeObject<List<RootObject>>(jsonString);

      }
    }
}
