Is it possible to ignore null values in a rest response?

Question

I have a rest service that returns a json. Everything is working and i was wondering if i could ignore null values in respose because i don't want to send something like:

{
"name": "George",
"country": null,
"city": null
}

I would like to return something like:

{
"name": "George"
}

The object that represents a Client is like that:

namespace Tests.Domain
{

public class Client
{
    public Client() { }

    [DataMember]
    public string Name{ get; set; }
    [DataMember]
    public Country Country { get; set; }
    [DataMember]
    public City City { get; set; }

}
}

And my response is:

...
return Request.CreateResponse((HttpStatusCode)200, clientSession);

Thanks in advance.

In your WebApiConfig.Register method, add the following code after route registration code:

   var jsonConfig = config.Formatters.JsonFormatter;
   jsonConfig.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
