I´m need to parse a json object into a c# class, my problem is that json object has a nested array and it´s throwing some errors when parsing.

I have tried a couple of options: a) do foreach in the elements of nested array, and add them to a new array b) parsing using json.deserialize

No success so far

These are my c# classes

public class itemPrediccion
{
    public string ClavePartido { get; set; }
    public string Ganador { get; set; }
    public bool EsFavorito { get; set; }
}

public class Prediccion
{
    public ObjectId _id { get; set; }
    public string IdUsuario { get; set; }
    public int Jornada { get; set; }
    public IEnumerable<itemPrediccion> PrediccionesJornada { get; set; }
}

An object of class "Prediccion" would contain a list of "itemPrediccion"

This is the json object that I want to parse to a "Prediccion" object

   {
"IdUsuario" : "user1", 
"Jornada" : "1",
"PrediccionesJornada" : [
    {
        "ClavePartido" : "AP2019J1P1",
        "Ganador": "Morelia",
        "EsFavorito": "false"
    },
    {
        "ClavePartido" : "AP2019J1P2",
        "Ganador": "Chivas",
        "EsFavorito": "false"
    },
    {
        "ClavePartido" : "AP2019J1P3",
        "Ganador": "Atlas",
        "EsFavorito": "true"
    }
]
}

This is how I´m trying to deserialize

string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);

Prediccion prediccionUsuario = new Prediccion {
                    IdUsuario = data.IdUsuario,
                    Jornada = data.Jornada,
                    PrediccionesJornada = data.PrediccionesJornada
                };

Throws this error:

Cannot implicitly convert type 'Newtonsoft.Json.Linq.JArray' to 'System.Collections.Generic.IEnumerable'. An explicit conversion exists (are you missing a cast?)

I see you have development companies on your tagline. Why not use them?
