c＃反序列化时出错：集合的大小固定

Question

我试图对一个对象进行序列化和反序列化，在第二部分（full json），它不适用于它的某个特定部分：

"Players": {
   "$type": "Player[], Classes",
    "$values": [
      {
        "$type": "Human, Classes",
        "Color": 1,
        "NbAction": 0,
        "Name": "toto"
      },
      {
        "$type": "IA, Classes",
        "Level": {
          "$type": "NoobLevel, Classes"
        },
        "Color": 0,
        "NbAction": 0,
        "Name": "tata"
      }
    ]
},

我明白了一个相当普通的问题：Collection was of fixed size但是因为没有堆栈痕迹或者我不知道该去哪里，因为我不知道不习惯c#它不是很容易

我首先得到此错误，因为某个元素是在构造函数中创建的，所以我为JSON创建了另一个具有良好参数的元素，但对于这个...我将Console.write()放入每个构造函数都帮助我，但不是

存储的相关类：

public class MementoGame
{
    private Board _plateau;
    private List<Player> _players;
    private int _numTurn;
    private int indexCurrentPlayer;

    //properties

    public MementoGame(Board plateau, Player[] players, int numTurn, int index)
    {
        Console.WriteLine("CONSTRUC MEMENTO BASE");
        _plateau = plateau; Players = players;  _numTurn = numTurn; IndexCurrentPlayer = index;
    }

    [JsonConstructor]
    public MementoGame(Board plateau, int numTurn, int indexCurrentPlayer, params Player[] players)
    {
        Console.WriteLine("CONSTRUC MEMENTO JSON");
        _plateau = plateau;
        for (int i = 0; i < players.Length; i++)
        {
            Console.Write(players[i] + " / ");                
        }
        _players = new List<Player>(players);
        _numTurn = numTurn;
        IndexCurrentPlayer = indexCurrentPlayer;
    }
}

序列化的方法：

public void saveToFile()
{
    string json = JsonConvert.SerializeObject(getMementoGame(), Formatting.Indented ,
           new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All });
    File.WriteAllText(@"C:\Users\...\care\" + link, json);
}

public void loadFromFile()
{
    string json = File.ReadAllText(@"C:\Users\...\care\" + link);
    MementoGame mem = JsonConvert.DeserializeObject<MementoGame>(json,
        new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All});
}

• MementoGame无法工作的无参数构造函数
• List<Player> players而不是params Player[] players无法正常工作
