c# - 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);
                        }

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() );
