Question

我已经对我的应用程序进行了几周的编码，当这个错误突然出现时，一切正常。我能够将错误的原因缩小到这一行：

 var subscriptions = JsonConvert.DeserializeObject<SubscriptionList>(json);

我的反序列化在过去一直运作良好，但现在它突然崩溃了。我在一个尝试中包围它并捕获一个JSONException，但不是异常捕获它我的应用程序只是崩溃。我知道这是这一行，因为当我评论它时，应用程序运行完美。我搜索了日志猫试图找到一个错误，这就是它

W/Binder  ( 1168): Caught a RuntimeException from the binder stub implementation.

我正在尝试完全反序列化这个JSON

{"list":[{"appId":"urn:aid:f104430c-d4f9-4ae6-850d-304ded2a583b","updatedAt":"2018-06-01T19:52:14Z","businessId":"a7c8b6ae-70e3-4b77-be64-769938d611ed","createdAt":"2018-06-01T19:52:13Z","phase":"TRIAL","planId":"c8584ffd-545f-4e38-9e97-55337e6cefe4","subscriptionId":"ec3d1e84-2695-45a8-8450-72daae4e2b30","startAt":"2018-06-01T00:00:00Z","status":"ACTIVE","replace":false,"bundled":false}],"start":0,"total":1}

这是我的类，一个名为SubscriptionList，一个名为Subscription

class SubscriptionList
    {
        [JsonProperty("list")]
        public List<Subscription> list = new List<Subscription>();
        [JsonProperty("start")]
        public int start;
        [JsonProperty("total")]
        public int total;
        [JsonProperty("count")]
        public int count;

        public SubscriptionList(List<Subscription> list,int s,int t,int count)
        {
            this.count = count;
            this.list = list;
            start = s;
            total = t;
        }
    }
public class Subscription
    {


        [JsonProperty("businessId")]
        public string businessId { get => businessId; set => businessId = value; }
        [JsonProperty("planId")]
        public string planId { get => planId; set => planId = value; }
        [JsonProperty("subscriptionId")]
        public string subscriptionId { get => subscriptionId; set => subscriptionId = value; }



        [JsonProperty("appId")]
        public string appId;
        [JsonProperty("phase")]
        public string phase;
        [JsonProperty("replace")]
        public bool replace;
        [JsonProperty("bundled")]
        public bool bundled;
        [JsonProperty("status")]
        public string status;

        public Subscription(string bus,string plan,string sub)
        {
            businessId = bus;
            planId = plan;
            subscriptionId = sub;
        }

    }

即使在我调用此方法之前，我正在对应用程序中的其他任何地方进行反序列化。最让我困扰的是，我无法找到一个简单的JSON错误。谢谢。
