Question

我正在向端点发送API请求并收到响应。

我有一个对象RootResponse，该对象永远不会是列表，并且永远是单个对象。

在此对象中有一个名为Package的对象，在其中是一个名为Activity的对象。

此活动对象表示承运人扫描包裹时的信息。但是，有时在包装上可能只有1次扫描，在这种情况下，当我将JSON响应反序列化为RootResponse对象时，会出现以下错误

Batchtracker.Models.TrackingAPI.Response.Activity[]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type

我尝试将对象Activity的类型更改为List<Activity>和Activity[]，但仍然出错。我知道问题在于，只有一个活动扫描时，它只会作为单个对象而不是数组返回。我该如何解决这个问题？

这是反序列化之前只有一次扫描的响应活动对象的示例

"Activity": {
  "ActivityLocation": {
    "Address": {
      "CountryCode": "US"
    }
  },
  "Status": {
    "Type": "M",
    "Description": "Order Processed: Ready for UPS",
    "Code": "MP"
  },
  "Date": "20190426",
  "Time": "135618"
},
