Question

here’s my problem:

I’m trying to deserialize json that hasn’t been done by me. The format of the json is as follows:

{"responseId":1200,
"availableHotels":[
    {"processId":"HA-84665605","hotelCode":"UKKTLT","availabilityStatus":"InstantConfirmation",...},
    {"processId":"HA-28600965","hotelCode":"UKKTLT","availabilityStatus":"InstantConfirmation",...},
    {"processId":"HI-63991185","hotelCode":"UKJOVF","availabilityStatus":"InstantConfirmation",...}
],
"totalFound":9,
"searchId":"TP-84026455"}

And the following classes:

• getAvailableHotelResponse w/properties:
  • hotelObj availableHotels
  • int totalFound
  • String responseId
  • String searchId
• hotelObj w/properties:
  • hotel hotel
• hotel w/properties:
  • processId
  • hotelCode
  • availabilityStatus
  • …

Therefore, what I know I can tell from looking at the json is that it contains information of a getAvailableHotelResponse object.

So, I tried the following using JsonConvert and JavaScriptSerializer:

JavaScriptSerializer ser = new JavaScriptSerializer();
getAvailableHotelResponse availableResponse = ser.Deserialize<getAvailableHotelResponse>(json);
// Exception: "Type 'com.hotelspro.api.getAvailableHotelResponse' is not supported for deserialization of an array"

List<getAvailableHotelResponse> items = ser.Deserialize<List<getAvailableHotelResponse>>(json);
// items.Count = 0

List<getAvailableHotelResponse> result = JsonConvert.DeserializeObject<List<getAvailableHotelResponse>>(json);
// Exception: "Cannot deserialize JSON object into type 'System.Collections.Generic.List`1[com.hotelspro.api.getAvailableHotelResponse]'."

getAvailableHotelResponse result2 = JsonConvert.DeserializeObject<getAvailableHotelResponse>(json);
// Exception: Cannot deserialize JSON array into type 'com.hotelspro.api.hotelObj'.

What’s the correct sentence in order to deserialize this object?

Thanks!

It’s difficult to interpret the structure of your objects based on your description but I was able to deserialize your sample JSON using the following minimal code:

var result = JsonConvert.DeserializeObject<getAvailableHotelResponse>(json);

public class getAvailableHotelResponse
{
    public int responseId;
    public availableHotel[] availableHotels;
    public int totalFound;
    public string searchId;
}

public class availableHotel
{
    public string processId;
    public string hotelCode;
    public string availabilityStatus;
}
