我目前正在撰寫 Xamarin 表單應用程式。我面臨的問題是我從我的 API 接收到一個 Json 回應，并將它存盤在一個 var JsonReponse 中。代碼如下；
string UserId = Settings.CallUserId;
var client = new RestClient("http://blablablaAPiCall" UserId);
client.Timeout = -1;
var request = new RestRequest(Method.GET);
request.AddHeader("Content-Type", "application/json");
var body = @"";
request.AddParameter("application/json", body, ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);
var JsonResponse = JsonConvert.DeserializeObject<Flights[]>(response.Content);
FlightsCollection = new ObservableCollection<Flights>
{
new Flights() {Id="1", SectorStart="1", Registration="A123",
Departure="Jhb", OffBlockTime="1242", Arrival="EC", OnBlockTime="1342",
TotalFlightTime="0100", InstrumentTime="00" }
};
我制作的課程看起來像這樣；公共類航班{
public string Id { get; set; }
public string UserId { get; set; }
public string EntryDate { get; set; }
public string IsMasterId { get; set; }
public string SectorStart { get; set; }
public string SectorEnd { get; set; }
public string AircraftType { get; set; }
public string Registration { get; set; }
public string PicName { get; set; }
public string PilotFunction { get; set; }
public string Departure { get; set; }
public string Arrival { get; set; }
public string OffBlockTime { get; set; }
public string OnBlockTime { get; set; }
public string TotalFlightTime { get; set; }
public string NightLanding { get; set; }
public string Instructor { get; set; }
public string Simulator { get; set; }
public string NightTime { get; set; }
public string DayTime { get; set; }
public string InstrumentTime { get; set; }
public string ApproachType { get; set; }
public string NavAid { get; set; }
public string Place { get; set; }
public string FinalRemarks { get; set; }
}
在頂部，我宣告了一個 Obvservable 集合，public ObservableCollection FlightsCollection { get; 放; }
所以現在我的最終目標是設定我的 json response = Observable 集合，正如你所看到的，我已經靜態地完成了，但現在我如何用我的 json 回應來做到這一點？
如果需要，我的 json 回應如下所示，

uj5u.com熱心網友回復：
ObservableCollection接受一個IEnumerable其DeserializeObject可以生成。試試這個：
FlightsCollection = new ObservableCollection<Flights>(JsonConvert.DeserializeObject<List<Flights>>(response.Content))
uj5u.com熱心網友回復：
如果你只想擁有一些屬性，你可以根據你的需要創建子類
FlightBase[] flights = JsonConvert.DeserializeObject<FlightBase[]>(response.Content);
ObservableCollection<FlightBase> FlightsCollection = new ObservableCollection<FlightBase>(flights);
班級
public class FlightBase
{
public int ID { get; set; }
public int SectorStart { get; set; }
public string Registration { get; set; }
public string Departure { get; set; }
public string Arrival { get; set; }
public string OffBlockTime { get; set; }
public string OnBlockTime { get; set; }
public string TotalFlightTime { get; set; }
public string InstrumentTime { get; set; }
}
public class Flight:FlightBase

public int UserID { get; set; }
public string EntryDate { get; set; }
public bool IsMasterID { get; set; }
public int SectorEnd { get; set; }
public string Aircraft_Type { get; set; }
public string PICName { get; set; }
public string PilotFunction { get; set; }
public bool NightLanding { get; set; }
