我是一个新手与Json的东西。我有一个项目，正在使用牛顿软件。我有这个对象
'

namespace ConsoleApp1
{
    [JsonObject(MemberSerialization.OptIn)]
    public class Data
    {

        [JsonProperty]
        public bool IsActive { get; set; } = false;

        [JsonProperty]
        public string Source { get; set; }

        [JsonProperty]
        public object SourceData { get; set; }

        [JsonProperty]
        public bool IsClickable { get; set; } = true;

        [JsonConstructor]
        public Data(string Source = "", string SourceData = "", bool IsActive = false, bool IsClickable = true)
        {
            this.IsActive = IsActive;
            this.Source = Source;
            this.SourceData = SourceData;
            this.IsClickable = IsClickable;
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            JsonSerializerSettings JsonSettings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.Auto, NullValueHandling = NullValueHandling.Ignore };
            Data data = new Data() { IsActive = true, Source = "test", SourceData = new List<int> { 1, 2, 3 }, IsClickable = false };
            string json = JsonConvert.SerializeObject(data, Formatting.Indented, JsonSettings);
            Console.WriteLine(json);
            Data dataDes = JsonConvert.DeserializeObject<Data>(json, JsonSettings);
            Console.WriteLine(dataDes);
        }
    }
}

'
所以当它被序列化时，我得到了这个：
'

{
  "IsActive": true,
  "Source": "test",
  "SourceData": {
    "$type": "System.Collections.Generic.List`1[[System.Int32, System.Private.CoreLib]], System.Private.CoreLib",
    "$values": [
      1,
      2,
      3
    ]
  },
  "IsClickable": false
}

'
但是当它被反序列化时，我得到这个错误：Newtonsoft.Json.JsonReaderException:'分析值时遇到意外字符：{。路径“SourceData”，第4行，位置17。'
我是否忘记在某个地方设置一些东西，以使元数据在反序列化时工作？
