ServiceStack: Deserializing a Collection of JSON objects - json

Question

I have a simple json string which contains a collection of objects
http://sandapps.com/InAppAds/ads.json.txt
When I call GetAsync to get the objects, the collection returns 1 element instead of 4 and it's empty:
new JsonServiceClient ().GetAsync<List<CrossSell>> (url, Success, Failure);
My class is simple:
class CrossSell
{
public string ID { get; set; }
public string AppCategory { get; set; }
public string AppID { get; set; }
public string Name { get; set; }
public string ImageUrl { get; set; }
public string Copy { get; set; }
public string Device { get; set; }
public string Link { get; set; }
}

Answer 1

The JSON assumes a response DTO like:
class CrossSellResponse {
List<CrossSell> CrossSells { get; set; }
}
new JsonServiceClient().GetAsync<CrossSellResponse> (url, Success, Failure);
and not a bare array as your C# example suggests:
new JsonServiceClient ().GetAsync<List<CrossSell>> (url, Success, Failure);

Answer 2

I found the answer. You need to create an overall wrapper class that holds the JSON response. I call mine CrossSellResponse
public class CrossSellResponse
{
public List< CrossSell> CrossSells {get; set;}
}
The class CrossSell defines the data in the collection and matches the field names in a case sensitive way. The name of the response payload property CrossSells matches the name of the collection in the json stream.
