How to serialize object into JSON Format?

private static string SerializeObjectIntoJson(Person p)

    {

        DataContractJsonSerializer serializer = new  DataContractJsonSerializer(p.GetType());

        using (MemoryStream ms = new MemoryStream())

        {

            serializer.WriteObject(ms, p);

            ms.Flush();



            byte[] bytes = ms.GetBuffer();

            string jsonString = Encoding.UTF8.GetString(bytes, 0, bytes.Length).Trim('\0');

            return jsonString;

        }

    }
