c# - C# 中对象(带数组)的 API

Question

我正在从 transportapi.com 返回数据并将其加载到对象中，但未包含 json 数组中的数据。

返回的json是:

{
  "atcocode": "490012745J",
  "smscode": "47889",
  "request_time": "2016-11-11T22:10:42+00:00",
  "departures": {
    "55": [
      {
        "mode": "bus",
        "line": "55",
        "line_name": "55",
        "direction": "Bakers Arms",
        "operator": "TFL",
        "date": null,
        "expected_departure_date": "2016-11-11",
        "aimed_departure_time": null,
        "expected_departure_time": "22:19",
        "best_departure_estimate": "22:19",
        "source": "Countdown instant"
      }
    ]
  }
}

Controller 代码:

var source = "http://transportapi.com/v3/uk/bus/stop/490012745J/live.json?api_key=[key]&app_id=[appid]";

Uri sourceUri = new Uri(source);
System.Net.Http.HttpClient sourceClient = new System.Net.Http.HttpClient();
System.Net.Http.HttpResponseMessage sourceResponse = await sourceClient.GetAsync(sourceUri);
var sourceArray = await sourceResponse.Content.ReadAsStringAsync();

var selections = JsonConvert.DeserializeObject<RootObject>(sourceArray);

模型类:

public class BusDepartures
{
    public string mode { get; set; }
    public string line { get; set; }
    public string line_name { get; set; }
    public string direction { get; set; }
    public string busoperator { get; set; }
    public object date { get; set; }
    public string expected_departure_date { get; set; }
    public object aimed_departure_time { get; set; }
    public string expected_departure_time { get; set; }
    public string best_departure_estimate { get; set; }
    public string source { get; set; }
}

public class Departures
{
    // First attempt, use BusDepartures object.
    //public List<BusDepartures> BusDepartures { get; set; }

    // Second attempt (as "55" is an array), use array, then convert to object later.
    public string[] routes { get; set; }
}

public class RootObject
{
    public string atcocode { get; set; }
    public string smscode { get; set; }
    public string request_time { get; set; }
    public Departures departures { get; set; }
}

在 Departures 类中，我确实尝试创建一个 BusDepartures 对象来存储出发的详细信息，但我想知道，因为它是一个数组，我是否应该改用 routes 数组？但是，在单步执行代码时，BusDepartures 对象(未注释时)和路由数组均为空。

有什么想法吗？我错过了什么？

更新:

感谢 botond.botos 的回答。我将类(class)修改为

public class RootObject
{
    public string atcocode { get; set; }
    public string smscode { get; set; }
    public string request_time { get; set; }
    public IDictionary<int, IEnumerable<BusDepartures>> departures { get; set; }
}

它奏效了。

您不需要 Departures 类，并尝试按以下方式更改 RootObject 类:

public class RootObject
{
    public string atcocode { get; set; }
    public string smscode { get; set; }
    public string request_time { get; set; }
    public IDictionary<int, IEnumerable<BusDepartures>> departures { get; set; }
}
