在尝试将JSON字符串(包含多个对象)反序列化为List时,我遇到了一个我不明白的问题。这是JSON。
[
{
"id":2,
"name":"Race 1",
"raceDateTime":"2017-09-02T14:27:39.654",
"raceStartTime":"2017-09-02T14:27:39.654",
"description":"string",
"maxEntries":0,
"currentEntries":0,
"status":0
},
{
"id":3,
"name":"Race 2",
"raceDateTime":"2017-09-02T14:27:39.654",
"raceStartTime":"2017-09-02T14:27:39.654",
"description":"string",
"maxEntries":0,
"currentEntries":0,
"status":0
},
{
"id":4,
"name":"Race 3",
"raceDateTime":"2017-09-02T14:27:39.654",
"raceStartTime":"2017-09-02T14:27:39.654",
"description":"string",
"maxEntries":0,
"currentEntries":0,
"status":0
},
{
"id":5,
"name":"Race 4",
"raceDateTime":"2017-09-02T14:27:39.654",
"raceStartTime":"2017-09-02T14:27:39.654",
"description":"string",
"maxEntries":0,
"currentEntries":0,
"status":0
}
]
然后我将JSON参数与我的模型匹配。
public class RaceModel
{
public int id { get; set; }
public string name { get; set; }
public DateTime raceDateTime { get; set; }
public DateTime raceStartTime { get; set; }
public string description { get; set; }
public int maxEntries { get; set; }
public int currentEntries { get; set; }
public int status { get; set; }
}
public class RaceList
{
public List<RaceList> racelist { get; set; }
}
我从REST API请求中获取JSON的代码如下:
string APIServer = Application.Current.Properties["APIServer"].ToString();
string Token = Application.Current.Properties["Token"].ToString();
var client = new RestClient(APIServer);
var request = new RestRequest("api/race", Method.GET);
request.AddHeader("Content-type", "application/json");
request.AddHeader("Authorization", "Bearer " + Token);
var response = client.Execute(request) as RestResponse;
var raceobject = JsonConvert.DeserializeObject<RaceList>(response.Content);
但我收到此错误(使用Newtonsoft.JSON)
Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'TechsportiseApp.API.Models.RaceList' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
Path '', line 1, position 1.
我希望有一个列表/对象集合,然后我可以迭代并使用它。
有人可以告诉我做错了吗?
答案 0 :(得分:4)
您的响应是一个对象数组,您在T参数中指定了一个对象。使用List<RaceModel>
代替RaceList
:
var raceobject = JsonConvert.DeserializeObject<List<RaceModel>>(response.Content);
