Hi,

I'm trying to serialize (and deserialize) an enum to it's member value, not an integer.  This technique is mentioned in this microsoft article http://msdn.microsoft.com/en-us/library/aa347875.aspx but it dosen't work.

Does anyone know how to do it?

Here is some sample code

    [DataContract]
    public class Car
    {
        [DataMember]
        public string model;
        [DataMember]
        public CarConditionEnum condition;
    }

    [DataContract(Name = "CarCondition")]
    public enum CarConditionEnum
    {
        [EnumMember]
        New,
        [EnumMember]
        Used,
        [EnumMember]
        Rental,
        Broken,
        Stolen
    }

    class Program
    {
        public static string SerialiseJSON<E>(E obj)
        {
            MemoryStream memoryStream = new MemoryStream();
            SerialiseJSON<E>(memoryStream, obj);
            return Encoding.Default.GetString(memoryStream.ToArray());
        }

        public static void SerialiseJSON<E>(Stream stream, E obj)
        {
            DataContractJsonSerializer dataContractJsonSerializer = new DataContractJsonSerializer(typeof(E));
            dataContractJsonSerializer.WriteObject(stream, obj);
        }

        static void Main(string[] args)
        {
            Car car = new Car();
            car.condition = CarConditionEnum.New;
            car.model = "Holden";

            string JSON = SerialiseJSON<Car>(car);
            Console.Write(JSON);
        }
    }

Output is:

{"condition":0,"model":"Holden"}

Expected Output:

{"condition":"New","model":"Holden"}

Thanks,

It looks like it should output "New". As an experiment, try that with the DataContrractSerializer, just so we can see if the problem is specific to JSON.
