我现在真的被这个问题困扰了 2 天，如何从深度嵌套的 json 对象中获取数据。
我找到了一个在线 json 工具http://www.jsoneditoronline.org/ http://jsonformat.com/ 当您将 json 粘贴到其中时，它会显示所有对象数组等，因此我可以深入研究数据并得到我想要的信息。
当我调试代码并设置断点时： foreach (JToken data in rates.ToArray())我可以看到我所追求的数据，我只是无法将数据取出，取决于我尝试的内容取决于我得到的错误，最后一个错误是。
将值“@rateChange”转换为类型“Web.UI.Controllers.HomeController+RateInfo”时出错。
无法从 System.String 转换或转换为 Web.UI.Controllers.HomeController+RateInfo。
对此的任何帮助都非常感谢。
我的课
public class RateInfo
{
public string RateChange { get; set; }
public string Promo { get; set; }
public string PriceBreakdown { get; set; }
public bool NonRefundable { get; set; }
public string RateType { get; set; }
public int CurrentAllotment { get; set; }
public int? PromoId { get; set; }
public string PromoDescription { get; set; }
public string PromoType { get; set; }
}
代码
IList<JToken> rates = root["HotelListResponse"]["HotelList"]["HotelSummary"][0]["RoomRateDetailsList"]["RoomRateDetails"]["RateInfos"]["RateInfo"].Children().ToList();
IList<RateInfo> info = new List<RateInfo>();
foreach (JToken data in rates.ToArray())
{
RateInfo rateInfo = JsonConvert.DeserializeObject<RateInfo>(data.ToString());
info.Add(rateInfo);
}

=============================此代码可以从汇总数组中获取数据============
public class Hotelsummary
{
public string Name { get; set; }
public string Address1 { get; set; }
public string Address2 { get; set; }
public string City { get; set; }
public string PostalCode { get; set; }
public string CountryCode { get; set; }
public string ThumbNailUrl { get; set; }
public string ShortDescription { get; set; }
public double HotelRating { get; set; }
public double TripAdvisorRating { get; set; }
public string RateCurrencyCode { get; set; }
}
public IEnumerable<Hotelsummary> GetHotelsForLocationSearch()
{
var hotelDetails = GetHotelsFromEan.GetListOfHotels();
var root = JObject.Parse(hotelDetails.ToString());
IList<JToken> hotels = root["HotelListResponse"]["HotelList"]["HotelSummary"].Children().ToList();
IList<Hotelsummary> hotelsummaries = hotels.Select(result => JsonConvert
.DeserializeObject<Hotelsummary>(
result.ToString())).ToList();
return hotelsummaries;
}
但是一旦我尝试更深入地挖掘数据，我就无法获得我需要的数据
