我无法弄清楚我做错了什么。我正在尝试反序列化具有多态对象的 JSON。这是我的基本课程和设置

public class Information
{
    [JsonConverter(typeOf(AccountConverter)]
    public list<BaseAccount> Accounts {get; set;}
    public decimal TotalBalance {get; set;}
    ...
}

public class BaseAccount
{
   public int Id {get; set;}
   public virtual AccountType Type { get;} //enum value that I base account type off of.
   ...
}

// I have a few different kinds of accounts but here is an example of one
public class BankAccount: BaseAccount
{
   public decimal value {get; set;}
   public override AccountType Type { get {return AccountType.Bank}
   ...
}

在我的 AccountConverter.cs 中，我创建了一个 ReadJson 方法，如下所示

    public override object? ReadJson(JsonReader reader, Type objectType, object? existingValue, JsonSerializer serializer)
{
    var jo = JObject.Load(reader);
    var account= jo.ToObject<BaseAccount>();
    if (account== null) throw new ArgumentOutOfRangeException();
    return account.Type switch
    {
        AccountType.Bank => jo.ToObject(typeof(BankAccount), serializer),
        ... // have multiple other account types
        _ => throw new ArgumentOutOfRangeException()
    };
}

我在我的响应方法中调用我的 deserializeObject

JsonConvert.DerserializeObject<Information>(result, JsonConverterSettings.Settings)

我不断在 ReadJson 方法的第一行收到错误。“从 JsonReader 读取 JObject 时出错。当前 JsonReader 项不是对象。StartArray。路径....”

我是否以正确的方式处理这个问题？
