Пытаюсь парсить с помощью Newtonsoft.Json, сгенерировал такие классы по json ответу:

public class BucketData
{
    public bool modifiable_by_user { get; set; }
    public bool @private { get; set; }

    public string bid { get; set; }
    public List<object> preview { get; set; }
    public string type { get; set; }
    public string set_id { get; set; }
    public int size { get; set; }
}
public class User
{
    public string short_name { get; set; }
    public string locale { get; set; }
    public bool has_profile_pic { get; set; }
    public bool is_admin { get; set; }
    public bool is_fb_user { get; set; }
    public string country_code { get; set; }
    public string gender { get; set; }
    public string id { get; set; }
    public string fb_uid { get; set; }

    public int num_rewards { get; set; }
    public int preview_size { get; set; }
    public int num_wishes { get; set; }

public class RootObject
{
    public string msg { get; set; }
    public int code { get; set; }
    public Data data { get; set; }
    public string sweeper_uuid { get; set; }
}

Например десереализирую:

var des = JsonConvert.DeserializeObject<User>(request.Response.ToString());
MessageBox.Show(des.country_code);

Но получаю неизвестно почему пустой MessageBox. Помогите, пожалуйста. Уже который час не могу понять почему так. Спасибо!
