c# - 如何从json中的不同类中获取数据值？例如使用其 id 的名称
问题描述
我目前正在用 c# 制作一个航班搜索应用程序。我将 json 绑定到 datagridview 中。到目前为止，这是我的代码。
var client = new RestClient("https://skyscanner-skyscanner-flight-search-v1.p.rapidapi.com/apiservices/browsequotes/v1.0/GB/GBP/en-GB/UK-sky/JFK-sky/2021-09-01?inboundpartialdate=2021-09-10");
var request = new RestRequest(Method.GET);
request.AddHeader("x-rapidapi-key", "d6deba1f4bmsh21094fa230617cdp180268jsn452ac752d55a");
request.AddHeader("x-rapidapi-host", "skyscanner-skyscanner-flight-search-v1.p.rapidapi.com");
IRestResponse response = client.Execute(request);
dynamic results = JsonConvert.DeserializeObject<Application>(response.Content);
DataTable table = new DataTable();
string quoteID;
string strPrice;
string Destination;
string Origin;
string Carrier;
string Dates;
foreach (var a in results.Quotes)
{
quoteID = String.Format("{0}", a.QuoteId);
Debug.WriteLine(quoteID);
strPrice = String.Format("{0:C}", a.MinPrice);
Debug.WriteLine(strPrice);
Destination = String.Format("{0}", a.OutboundLeg.DestinationId);
Debug.WriteLine("" + Destination);
Origin = String.Format("{0}", a.OutboundLeg.OriginId);
Debug.WriteLine("" + Origin);
Carrier = String.Format("{0}", a.OutboundLeg.CarrierIds[0]);
Debug.WriteLine("" + Carrier);
DateTime Date = a.OutboundLeg.DepartureDate;
Dates = Date.ToString("MM/dd/yyyy");
Debug.WriteLine("" + Dates);
dataGridView1.Rows.Add(
quoteID,
strPrice,
Carrier,
Destination,
Origin,
Dates);
}
这是我的json。

我遇到的问题是我正在尝试使用 outboundleg 类中提供给我的 ID 来获取承运人和城市的名称。例如，如果我有 ID 1247，我想获取 Carriers 类中的值“LEVEL”。为了达到其他类中的值，我需要什么样的代码。就您在我的代码中看到的而言，我可以获得每个报价的 id 编号，我的目标是打印出 datagridview 中的名称而不是数字。
编辑代码
foreach (var quote in quotesResponse.Quotes)
{
var carrierInfo = carriersResponse.Carriers
.Where(x => quote.OutboundLeg.CarrierIds.Contains(x.CarrierId))
.Select(x => x.Name);
var destinationInfo = destinationResponse.Places.FirstOrDefault(item => quote.OutboundLeg.DestinationIds == item.PlaceId);
strPrice = String.Format("{0:C}", quote.MinPrice);
Debug.WriteLine(strPrice);
DateTime Date = quote.OutboundLeg.DepartureDate;
Dates = Date.ToString("MM/dd/yyyy");
Debug.WriteLine("" + Dates);
dataGridView1.Rows.Add(
quote.QuoteId,
strPrice,
string.Join(", ", carrierInfo),
destinationInfo.Name,
quote.OutboundLeg.OriginId,
Dates);
}
