Question

我有一个Json如下。

{
  "currency": "MYR",
  "results": [
    {
      "itineraries": [
        {
          "outbound": {
            "flights": [
              {
                "departs_at": "2018-06-03T06:25",
                "arrives_at": "2018-06-03T07:25",
                "origin": {
                  "airport": "PEN"
                },
                "destination": {
                  "airport": "KUL",
                  "terminal": "M"
                },
                "marketing_airline": "OD",
                "operating_airline": "OD",
                "flight_number": "2105",
                "aircraft": "738",
                "booking_info": {
                  "travel_class": "ECONOMY",
                  "booking_code": "Q",
                  "seats_remaining": 9
                }
              }
            ]
          },
          "inbound": {
            "flights": [
              {
                "departs_at": "2018-06-04T14:10",
                "arrives_at": "2018-06-04T15:10",
                "origin": {
                  "airport": "KUL",
                  "terminal": "M"
                },
                "destination": {
                  "airport": "PEN"
                },
                "marketing_airline": "OD",
                "operating_airline": "OD",
                "flight_number": "2108",
                "aircraft": "739",
                "booking_info": {
                  "travel_class": "ECONOMY",
                  "booking_code": "O",
                  "seats_remaining": 5
                }
              }
            ]
          }
        }
      ],
      "fare": {
        "total_price": "360.00",
        "price_per_adult": {
          "total_fare": "360.00",
          "tax": "104.00"
        },
        "restrictions": {
          "refundable": false,
          "change_penalties": true
        }
      }
    }
  ]
}

我使用下面的代码从Json中检索值。我能够检索“departs_at”，“arrives_at”，“marketing_airline”但我无法检索“booking_info”中的值。

IOperations _obj = ClsOperations.GetOperations();
string url = "https://api.sandbox.amadeus.com/v1.2/flights/low-fare-search?apikey=" + APIKEY
    + "&origin=" + origin + "&destination=" + destination
    + "&departure_date=" + departureDate + "&return_date=" + returnDate
    + "&currency=" + currency + "&number_of_results=1";
string json = _obj.GetJsonResult(url);
JToken jToken = JToken.Parse(json);
JArray outBoundFlights = (JArray)jToken.SelectToken("results[0].itineraries[0].outbound.flights");
foreach (JToken obf in outBoundFlights)
{
    TravelPlan.Text += "Departs At: " + obf["departs_at"] + "<br/>";
    TravelPlan.Text += "Arrives At: " + obf["arrives_at"] + "<br/>";
    TravelPlan.Text += "Airline: " + obf["marketing_airline"] + "<br/>";
}
JArray outBoundFlightsBooking = (JArray)jToken.SelectToken("results[0].itineraries[0].outbound.flights.booking_info");
foreach (JToken obfb in outBoundFlightsBooking)
{
    TravelPlan.Text += "<br/>";
    TravelPlan.Text += "Travel Class: " + obfb["travel_class"] + "<br/>";
    TravelPlan.Text += "Seats Remaining: " + obfb["seats_remaining"] + "<br/>";
}

我想问一下如何才能检索booking_info中的值？感谢这里的每位成员提供帮助。

这就像魅力一样。

 string json = "{\"currency\": \"MYR\",  \"results\": [    {      \"itineraries\": [        {          \"outbound\": {            \"flights\": [              {                \"departs_at\": \"2018-06-03T06:25\",                \"arrives_at\": \"2018-06-03T07:25\",                \"origin\": {                  \"airport\": \"PEN\"                },                \"destination\": {                  \"airport\": \"KUL\",                  \"terminal\": \"M\"                },                \"marketing_airline\": \"OD\",                \"operating_airline\": \"OD\",                \"flight_number\": \"2105\",                \"aircraft\": \"738\",                \"booking_info\": {                  \"travel_class\": \"ECONOMY\",                  \"booking_code\": \"Q\",                  \"seats_remaining\": 9                }              }            ]          },          \"inbound\": {            \"flights\": [              {                \"departs_at\": \"2018-06-04T14:10\",                \"arrives_at\": \"2018-06-04T15:10\",                \"origin\": {                  \"airport\": \"KUL\",                  \"terminal\": \"M\"                },                \"destination\": {                  \"airport\": \"PEN\"                },                \"marketing_airline\": \"OD\",                \"operating_airline\": \"OD\",                \"flight_number\": \"2108\",                \"aircraft\": \"739\",                \"booking_info\": {                  \"travel_class\": \"ECONOMY\",                  \"booking_code\": \"O\",                  \"seats_remaining\": 5                }              }            ]          }        }      ],      \"fare\": {        \"total_price\": \"360.00\",        \"price_per_adult\": {          \"total_fare\": \"360.00\",          \"tax\": \"104.00\"        },        \"restrictions\": {          \"refundable\": false,          \"change_penalties\": true        }      }    }  ]}";
 RootObject travelInfo = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(json);

用于检索json响应中的所有bookingInfo。

        foreach(Result result in travelInfo.results)
        {
            foreach(Itinerary itn in travelInfo.results[0].itineraries)
            {
                //For Inbound Flights
                foreach (Flight2 fl2 in itn.inbound.flights)
                {
                    Console.WriteLine("BookingCode:"+fl2.booking_info.booking_code);
                    Console.WriteLine("Seats Remaining:" + fl2.booking_info.seats_remaining);
                    Console.WriteLine("Travel Class:" + fl2.booking_info.travel_class);
                }
                //For Outbound Flights
                foreach(Flight fl1 in itn.outbound.flights)
                {
                    Console.WriteLine("BookingCode:" + fl1.booking_info.booking_code);
                    Console.WriteLine("Seats Remaining:" + fl1.booking_info.seats_remaining);
                    Console.WriteLine("Travel Class:" + fl1.booking_info.travel_class);
                }
            }
        }

输出：

BookingCode：O型剩余座位：5 旅游类：经济 BookingCode：Q 剩余座位：9 旅游类：经济

将此C＃模型用于this link

的json

namespace Flighting
{
    using System;

    public partial class Flight
    {
        public static Flight FromJson(string json) => JsonConvert.DeserializeObject<Flight>(json, Flighting.Converter.Settings);
    }

    public static class Serialize
    {
        public static string ToJson(this Flight self) => JsonConvert.SerializeObject(self, Flighting.Converter.Settings);
    }

    internal static class Converter
    {
        public static readonly JsonSerializerSettings Settings = new JsonSerializerSettings
        {
            MetadataPropertyHandling = MetadataPropertyHandling.Ignore,
            DateParseHandling = DateParseHandling.None,
            Converters = {
                new IsoDateTimeConverter { DateTimeStyles = DateTimeStyles.AssumeUniversal }
            },
        };
    }
}

然后在课堂上使用它

var flight = Flighting.Flight.FromJson(yourjson);

         string currency   =   flight.Currency;
            var restrictions = flight.Results[0].Fare.Restrictions;
            var totalprice = flight.Results[0].Fare.TotalPrice;
            var adult = flight.Results[0].Fare.PricePerAdult;
            var a = flight.Results[0].Itineraries[0].Inbound.Flights[0].Aircraft;
            var bookingInfo = flight.Results[0].Itineraries[0].Inbound.Flights[0].BookingInfo;
            var d = flight.Results[0].Itineraries[0].Inbound.Flights[0].DepartsAt;
            var f = flight.Results[0].Itineraries[0].Inbound.Flights[0].FlightNumber;
            var op = flight.Results[0].Itineraries[0].Inbound.Flights[0].OperatingAirline;

适当循环，我使用索引零作为测试用例
