C＃反序列化JSON到列表

Question

尝试将JSON字符串（包含多个对象）反序列化为List时遇到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，我有与我的模型匹配的JSON参数。

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.

我想要一个对象的列表/集合，然后可以迭代并使用它们。

谁能告诉我我做错了什么？

您的响应是一个对象数组，并且您正在T参数中指定一个对象。使用List<RaceModel>代替RaceList：

var raceobject = JsonConvert.DeserializeObject<List<RaceModel>>(response.Content);
