You must mark all classes and properties of the DataContract and DataMember attributes. Using a piece of code, I created something like this:

[DataContract]
    public class Result
    {
        [DataMember(Name="responseCode")]
        public int Code { get; set; }

        [DataMember(Name="responseObject")]
        public ResponseObject Result { get; set; }
    }

    [DataContract]
    public class ResponseObject
    {
        [DataMember]
        public int TotalRecords { get; set; }

        [DataMember]
        public int TotalDisplayRecords { get; set; }

        [DataMember(Name="aaData")]
        public DataItem[] Data { get; set; }
    }

    [DataContract]
    public class DataItem
    {
        [DataMember(Name = "InvoiceId")]
        public int InvoiceId { get; set; }

        // Others properties
    }
