Задача состоит в том, чтобы заполнить все поля класса Order при десериализации, в том числе поле Pair.
Как я могу это сделать:

C#
1
2
3
4
5
6
7
8
9
10
11
12
            JObject jObject = JObject.Parse(JSON);
            Dictionary<string, List<Order>> dict = new Dictionary<string, List<Order>>();
            foreach (var pair in jObject)
            {
                List<Order> orders = new List<Order>();
                foreach (var order in pair.Value.ToObject<List<Order>>())
                {
                    order.Pair = pair.Key;
                    orders.Add(order);
                }
                dict.Add(pair.Key, orders);
            }

Хочется сделать так, чтобы поле Pair заполнялось уже во время десериализации, т.е. работал вот такой код:

C#
1
2
            JObject jObject = JObject.Parse(JSON);
            Dictionary<string, List<Order>> dict = jObject.ToObject<Dictionary<string, List<Order>>>();

Куда копать?..
