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);
        }
