JSON Question

Getting data from a deeply nested json object

I'm really stuck on this problem now for 2 days, how can I get the data out of a deeply nested json object.

I have found an online json tools http://www.jsoneditoronline.org/ http://jsonformat.com/ which when you paste your json into it, shows all the objects arrays etc, so I can dig down into the data and get the information I want.

When I debug the code and put a break point on:

foreach (JToken data in rates.ToArray())
I can see the data I'm after, I just cannot get the data out, depends on what I try depends on the error I get, last error was.


Error converting value "@rateChange" to type
'Web.UI.Controllers.HomeController+RateInfo'.

Could not cast or convert from System.String to Web.UI.Controllers.HomeController+RateInfo.


Any help with this is much appreciated.

My class

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; }
}


code

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);
}

=============================This code works getting data out of summary array============

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;
}


But as soon as I try digging deeper into data, I cannot get the data I needs

Answer Source

Try this instead:

IList<JToken> rates = root["HotelListResponse"]["HotelList"]["HotelSummary"][0]["RoomRateDetailsList"]["RoomRateDetails"]["RateInfos"].Children().ToList();

EDIT:

var rateInfo = json["HotelListResponse"]["HotelList"]["HotelSummary"][0]["RoomRateDetailsList"]["RoomRateDetails"]["RateInfos"]["RateInfo"];

var result =JsonConvert.DeserializeObject<RateInfo>( rateInfo .ToString() );
