json反序列化对象

这个是同事研究的wcf中中根据type类型反序列化json的示例

 /// <summary>

        /// json转对象

        /// </summary>

        /// <param name="json"></param>

        /// <param name="type"></param>

        /// <returns></returns>

        public static object DataContractJsonSerializer(string json, Type type)

        {

            DataContractJsonSerializer serializer = new DataContractJsonSerializer(type);

            MemoryStream mStream = new MemoryStream(Encoding.UTF8.GetBytes(json));

            return serializer.ReadObject(mStream);

        }
