Serialize Unknown Types with DataContractJsonSerializer

Question

i have this method to serialize my objects :

    private static byte[] GetBytes(object obj) {
        byte[] result;
        using (MemoryStream ms = new MemoryStream()) {
            DataContractJsonSerializer ser = new DataContractJsonSerializer(obj.GetType());

            ser.WriteObject(ms, obj);
            result = ms.ToArray();
            ms.Close();
        }
        return result;
    }

it is normal, when i want to use this, my object parameter must a class that decorate with [System.Runtime.Serialization.DataContract] and its member must decorate with [System.Runtime.Serialization.DataMember] but how about when i want to use unknown type like :

var myVar = GetBytes(new { Name = "MyName", LastName = "LastName" });

how can i decorate unknown types with attribute

DataContractJsonSerializer does not work with Anonymous Types. Consider simply sending a Dictionary over the wire if defining a specific Type with DataContract is not possible/justified.

Take a look at this thread also How do I serialize a C# anonymous type to a JSON string?.
