How to convert this type of json response into User defined types

api, c#, json, user-defined-types, web-services

Solution

Remove non-compilable constructors like `public pax();` and just use

var availHotels = JsonConvert.DeserializeObject<getAvailableHotelResponse>(text);

that's all.

In fact, you wouldn't even need to declare this bunch of classes(`getAvailableHotelResponse`, `hotel`,`roomResponse`,`pax`,`dailyRate` etc.) if you made use of dynamic. For ex,

dynamic response = Newtonsoft.Json.JsonConvert.DeserializeObject(text);

foreach (var hotel in response.availableHotels)
{
    Console.WriteLine(hotel.processId);
    foreach (var room in hotel.rooms)
    {
        Console.WriteLine("\t" + room.roomCategory);
    }
}

Problem

I am using a web service which returns data into JSON in following format ``` { "responseId": 2933574, "availableHotels": [ { "processId": "HC-65870953", "hotelCode": "UKI9E6", "availabilityStatus": "InstantConfirmation", "totalPrice": 971, "totalTax": 0, "totalSalePrice": 0, "currency": "EUR", "boardType": "Bed & Continental Breakfast", "rooms": [ { "roomCategory": "Triple Room", "paxes": [ { "paxType": "Adult", "age": 30 }, { "paxType": "Adult", "age": 30 }, { "paxType": "Child", "age": "6" } ], "totalRoomRate": 486, "ratesPerNight": [ { "date": "2012-07-20", "amount": 163 }, { "date": "2012-07-21", "amount": 163 }, { "date": "2012-07-22", "amount": 160 }, { "date": "2012-07-23", "amount": 0 } ] }, { "roomCategory": "Triple Room", "paxes": [ { "paxType": "Adult", "age": 30 }, { "paxType": "Adult", "age": 30 }, { "paxType": "Child", "age": "8" } ], "totalRoomRate": 485, "ratesPerNight": [ { "date": "2012-07-20", "amount": 163 }, { "date": "2012-07-21", "amount": 163 }, { "date": "2012-07-22", "amount": 160 }, { "date": "2012-07-23", "amount": -1 } ] } ] }, { "processId": "HH-22003963", "hotelCode": "UKPDNN", "availabilityStatus": "InstantConfirmation", "totalPrice": 1085, "totalTax": 0, "totalSalePrice": 0, "currency": "EUR", "boardType": "Bed and Breakfast", "rooms": [ { "roomCategory": "Triple Room", "paxes": [ { "paxType": "Adult", "age": 30 }, { "paxType": "Adult", "age": 30 }, { "paxType": "Child", "age": "6" } ], "totalRoomRate": 544, "ratesPerNight": [ { "date": "2012-07-20", "amount": 136 }, { "date": "2012-07-21", "amount": 136 }, { "date": "2012-07-22", "amount": 136 }, { "date": "2012-07-23", "amount": 136 } ] }, { "roomCategory": "Triple Room", "paxes": [ { "paxType": "Adult", "age": 30 }, { "paxType": "Adult", "age": 30 }, { "paxType": "Child", "age": "8" } ], "totalRoomRate": 541, "ratesPerNight": [ { "date": "2012-07-20", "amount": 136 }, { "date": "2012-07-21", "amount": 136 }, { "date": "2012-07-22", "amount": 136 }, { "date": "2012-07-23", "amount": 133 } ] } ] } ], "totalFound": 2, "searchId": "QG-67623913" } ``` Now I have a class defined as following: ``` public class getAvailableHotelResponse { public getAvailableHotelResponse(); public hotel[] availableHotels { get; set; } [SoapElement(DataType = "integer")] public string responseId { get; set; } public string searchId { get; set; } [SoapElement(DataType = "integer")] public string totalFound { get; set; } } ``` And the `hotel` class is as follows: ``` public class hotel { public hotel(); public string availabilityStatus { get; set; } public string boardType { get; set; } public string currency { get; set; } public string hotelCode { get; set; } public string processId { get; set; } public roomResponse[] rooms { get; set; } [SoapElement(DataType = "integer")] public string specialDeal { get; set; } public float totalPrice { get; set; } [SoapIgnore] public bool totalPriceSpecified { get; set; } public float totalSalePrice { get; set; } [SoapIgnore] public bool totalSalePriceSpecified { get; set; } public float totalTax { get; set; } [SoapIgnore] public bool totalTaxSpecified { get; set; } } ``` And the `roomResponse` class is as follows: ``` public class roomResponse { public roomResponse(); public pax[] paxes { get; set; } public dailyRate[] ratesPerNight { get; set; } public string roomCategory { get; set; } public float totalRoomRate { get; set; } [SoapIgnore] public bool totalRoomRateSpecified { get; set; } } ``` And `pax` class is as follows: ``` public class pax { public pax(); [SoapElement(DataType = "integer")] public string age { get; set; } public string firstName { get; set; } public string lastName { get; set; } public string paxType { get; set; } public string title { get; set; } } ``` And `dailyRate` class is as follows: ``` public class dailyRate { public dailyRate(); public float amount { get; set; } [SoapIgnore] public bool amountSpecified { get; set; } [SoapElement(DataType = "date")] public DateTime date { get; set; } [SoapIgnore] public bool dateSpecified { get; set; } } ``` Edit ``` getAvailableHotelResponse h = new getAvailableHotelResponse(); h = (getAvailableHotelResponse)Newtonsoft.Json.JsonConvert.DeserializeObject(text); ``` I tried this and it's throwing the following error: Unable to cast object of type 'Newtonsoft.Json.Linq.JObject' to type 'hotelspro.getAvailableHotelResponse'. There is a really complex structure of JSON, so how do I convert this to my objects?
