[英]How to deserialize a JSON array with nested arrays of objects
I have a JSON string as follows and want to deserialize it: 我有一个JSON字符串如下,并想反序列化它:
[[{"campaignId":201410018,"programCode":"54321"}],[{"campaignId":201410018,"programCode":"54321"}]]
I have created some classes as follows: 我创建了一些类,如下所示:
public class Rootclass
{
public List<JSONResponse> rootClass { get; set; }
}
public class JSONResponse
{
public int campaignId { get; set; }
public string programCode { get; set; }
}
I am calling this JSON.NET method to deserialize the JSON: 我正在调用此JSON.NET方法来反序列化JSON:
List<Rootclass> myDeserializedObjList = (List<Rootclass>)Newtonsoft.Json.JsonConvert.DeserializeObject(json, typeof(List<Rootclass>));
But I am getting the error below: 但是我收到以下错误:
Cannot deserialize JSON array (i.e. [1,2,3]) into type 'JSON_Test.Rootclass'.
The deserialized type must be an array or implement a collection interface like IEnumerable, ICollection or IList.
What am I doing wrong? 我究竟做错了什么?
Your JSON represents a List<List<JSONResponse>>
, not a List<RootClass>
. 您的JSON表示一个
List<List<JSONResponse>>
,而不是List<RootClass>
。 Try it like this: 像这样尝试:
List<List<JSONResponse>> myDeserializedObjList =
JsonConvert.DeserializeObject<List<List<JSONResponse>>>(json);
