RestSharp Deserialization with JSON Array

Question

I have a JSON response that I'm trying to deserialize with RestSharp, and it looks like this:

{"devices":[{"device":{"id":7,"deviceid":"abc123","name":"Name"}},
            {"device":{"id":1,"deviceid":"def456","name":"Name"}}],
 "total":2,
 "start":0,
 "count":2}

Based off of some suggestions I've found, I've tried to setup my POCO like this:

public class DevicesList
{
    public List<DeviceContainer> Devices;
}

public class DeviceContainer
{
    public Device Device;
}

public class Device
{
    public int Id { get; set; }
    public string DeviceId { get; set; }
    public string Name { get; set; }
}

And then my execution looks like this:

// execute the request
var response = client.Execute<DevicesList>(request);

However, response.Data is NULL, and I've tried other variations with no luck.

So, what class structure and mapping should be used for this situation? I've also tried this without the extra DeviceContainer class.

Thanks for the help.

May be you should add total, start and count properties to deviceslist class. — Vladimir, Apr 22 '13 at 21:14

I had a slightly different issue when my deserialization POCO contained an array..

Changing it from Devices[] to List<Devices> resolved the issue and it deserialized correctly.

`IEnumerable<>` and `IList<>` don't work either. You need `List<>` – Adam Szabo Sep 25 '15 at 10:42

RestSharp only operates on properties, it does not deserialize to fields, so make sure to convert your Devices and Device fields to properties.

Also, double check the Content-Type of the response, if the responses is something non-default, RestSharp may not uses the JsonDeserializer at all. See my answer on RestSharp client returns all properties as null when deserializing JSON response

That was it. Stupid mistake forgetting the `{ get; set; }`. Once I added that, it worked perfectly. Thanks! – Garrett Vlieger Apr 23 '13 at 00:26

Something that I ran into is, it does not work if your using interfaces like: IEnumerable or IList, it has to be a concrete type.

This will not work, where as it does for some other json serializers like json.net.

public class DevicesList
{
    public IEnumerable<DeviceContainer> Devices { get; set; }
}

public class DeviceContainer
{
   ...
}

it would have to be something like this:

public class DevicesList
{
    public List<DeviceContainer> Devices { get; set; }
}

public class DeviceContainer
{
   ...
}

This helps if you are using a newer version of RESTSharp (e.g. not using JSON.NET) for your JsonDeserializer — Skyguard, Jun 12 '15 at 19:49

RestShartp doesn't support DataAnnotation/DataMember, rename your properties with no maj:

Devices -> devices
Device -> device

AND don't forget the {get; set;} ;).

My problem was entirely different, I naively thought JsonDeserializer supports JsonProperty attribute, but thats not true. So when trying to deserialize into

public class AvailableUserDatasApi
{
    [JsonProperty("available-user-data")]
    public List<AvailableUserDataApi> AvailableUserDatas { get; set; }
}

it failed.. But changing AvailableUserDatas to AvailableUserData was enough for things to start working.
