Я пытаюсь десериализовать этот ответ JSON с помощью конвертера JSON в C#. Раньше у меня никогда не было проблем, но с этим ответом результат преобразования довольно странный.

В любом случае, это ответ:

}

И это результат .

public class Parameters
    {
        public string league { get; set; }
        public string season { get; set; }
    }

    public class League
    {
        public int id { get; set; }
        public string name { get; set; }
        public string country { get; set; }
        public string logo { get; set; }
        public string flag { get; set; }
        public int season { get; set; }
        public IList<IList<>> standings { get; set; }
    }

    public class Response
    {
        public League league { get; set; }
    }

    public class Example
    {
        public string get { get; set; }
        public Parameters parameters { get; set; }
        public IList<object> errors { get; set; }
        public int results { get; set; }
        public IList<Response> response { get; set; }
    }

Как видите, там странный publi c IList<IList<>> standings { get; set; }. Я думаю, что это может зависеть от двойных квадратных скобок на постоянном теге, но я не так много работал с объектами Json.

Answer 1

Что бы вы ни делали - это больше всего похоже на то, что в вашем json есть массив массивов (список списков w / e), который что-то не может обработать.

Если я передаю это через quicktype я получаю следующее, что мне кажется лучше:

// <auto-generated />
//
// To parse this JSON data, add NuGet 'Newtonsoft.Json' then do:
//
//    using QuickType;
//
