为什么反序列化的 JSON 数组返回 null？

Question

我有一个JSON从 API 返回数据的字符串流，如下所示："{\"Recs\": [   {\"EID\":\"F67_24_6\",\"ReturnPeriod\":\"1\",\"GageStation\":\"NA\"},    {\"EID\":\"T67_24_6\",\"ReturnPeriod\":\"2.37\",\"GageStation\":\"Magueyes Island\"},    {\"EID\":\"R67_24_6\",\"ReturnPeriod\":\"1\",\"GageStation\":\"50147800\"}]}"我正在尝试反序列化它以返回：{"Recs":[          {"EID":"F67_24_6","ReturnPeriod":"1","GageStation":"NA"},           {"EID":"T67_24_6","ReturnPeriod":"2.37","GageStation":"Magueyes Island"},               {"EID":"R67_24_6","ReturnPeriod":"1","GageStation":"50147800"}]}我使用这些公共类来构建返回：public class New_Events_Dataset{    public string EID { get; set; }    public string ReturnPeriod { get; set; }    public string GageStation { get; set; }}public class NewRootObject{    public List<New_Events_Dataset> Reqs { get; set; }}当我稍后尝试应用此方法时，我基本上得到了{"Reqs":null}. 我在这里做错了什么？var jsonResponse = JsonConvert.DeserializeObject<NewRootObject>(strresult);string json = new JavaScriptSerializer().Serialize(jsonResponse);return json;

Answer 1

我认为Reqs应该是Recs：

     public class NewRootObject
    {
             public List<New_Events_Dataset> Reqs { get; set; }
    }

尝试：

    public class NewRootObject
    { 
            public List<New_Events_Dataset> Recs { get; set; }
     }

Answer 2

将Reqs重命名为Recs并创建类的默认构造函数并实例化 Recs 列表

public class NewRootObject

{

    List<New_Events_Dataset> Recs { get; set; }

    public NewRootObject()

    {

        Recs = new List<New_Events_Dataset>();

    }

}
