I have generated classes from json2csharp

public class From
{
    public int id { get; set; }
    public string first_name { get; set; }
    public string last_name { get; set; }
    public string username { get; set; }
}

public class Chat
{
    public int id { get; set; }
    public string first_name { get; set; }
    public string last_name { get; set; }
    public string type { get; set; }
    public string username { get; set; }
}

public class Entity
{
    public string type { get; set; }
    public int offset { get; set; }
    public int length { get; set; }
}

public class Message
{
    public int message_id { get; set; }
    public From from { get; set; }
    public Chat chat { get; set; }
    public int date { get; set; }
    public string text { get; set; }
    public List<Entity> entities { get; set; }
}

public class Result
{
    public int update_id { get; set; }
    public Message message { get; set; }
}

public class RootObject
{
    public bool ok { get; set; }
    public List<Result> result { get; set; }
}

using newtonsoft to deserialization

var d = Newtonsoft.Json.JsonConvert.DeserializeObject(rcvd_data);

what to do next? how to put this all at work? I am confused please help.

    To deserialization use this code:

    RootObject ro = JsonConvert.DeserializeObject<RootObject>(rcvd_data);

    And in ro you have all data.

    EXAMPLE

    bool ok = ro.ok;

foreach(Result r in ro.result)
{
    int uId = r.update_id;
    Message m = r.message;
    int msgId = m.message_id;
}

    Try this way

    var d = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(rcvd_‌​data);

    then d will contain list of RootObject. By iterating using foreach you can get all the properties of RootObject model

    string data = @"{""ok"":true,""result"":[{""update_id"":920493886,...";

RootObject ro = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(data);

foreach (Result result in ro.result)
{
        //two example fields
        Console.WriteLine("update_id= " + result.update_id);
        Console.WriteLine("message text= "+result.message.text);

    Based on: https://yts.am/api/v2/list_movies.json (Source: https://yts.am/api)

    I used: http://json2csharp.com/ to create classes
    Copy and paste the result of the get request of postman to json2csharp to automatically create the classes that you need

    And once created, i used them on a Service like this:

     private string URL = "https://yts.am/api/v2/list_movies.json";
    public async Task<List<Movie>> GetMovies()
    {
        var httpClient = new HttpClient();
        var json = await httpClient.GetStringAsync(URL);
        RootObject lista = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(json);
        List<Movie> todoes = lista.data.movies;
        return todoes;
    }

    I’m using Newtonsoft.Json
