就是将对象序列化为JSON并返回。还有一个与之相反的 public static T ParseFromJson<T>(string szJson) { T obj = Activator.CreateInstance<T>(); using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(szJson))) { DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType()); return (T)serializer.ReadObject(ms); } }
