.NET Oject And Json

　　在最近的项目开发中，需要将.NET 对象序列化为Json字符串，传递到客户端浏览器，同时，需要将客户端的Json字符串传递到Server,反序列化为.NET对象，主要有三种方式：

• 　　DataContractJsonSerializer

　　序列化：

/// <summary>
        /// 将.NET对象序列化为Json
        /// </summary>
        /// <typeparam name="T">.NET对象类型，此处为泛型</typeparam>
        /// <param name="obj">.NET对象</param>
        /// <returns>返回Json字符串</returns>
        public static string Serialize<T>(T obj)
        {
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
            MemoryStream ms = new MemoryStream();
            serializer.WriteObject(ms, obj);
            string returnString = Encoding.UTF8.GetString(ms.ToArray());
            return returnString;
        }

　　反序列化：

/// <summary>
        /// 将Json反序列化为.NET对象
        /// </summary>
        /// <typeparam name="T">.NET对象类型</typeparam>
        /// <param name="json">序列化字符串</param>
        /// <returns>返回.NET对象</returns>
        public static T Deserialize<T>(string json)
        {
            T obj = Activator.CreateInstance<T>();
            MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json));
            DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
            obj = (T)serializer.ReadObject(ms);
            ms.Close();
            return obj;
        }

• JavaScriptSerializer

　　序列化：

 /// <summary>
        /// 将.NET对象序列化为Json
        /// </summary>
        /// <typeparam name="T">.NET对象类型，此处为泛型</typeparam>
        /// <param name="obj">.NET对象</param>
        /// <returns>返回Json字符串</returns>
        public static string Serialize<T>(T obj)
        {
            System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
            return serializer.Serialize(obj);
        }

　　反序列化：

 /// <summary>
        /// 将Json反序列化为.NET对象
        /// </summary>
        /// <typeparam name="T">.NET对象类型</typeparam>
        /// <param name="json">序列化字符串</param>
        /// <returns>返回.NET对象</returns>
        public static T DeSerialize1<T>(string json)
        {
            System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
            return serializer.Deserialize<T>(json);
        }

　　我还是比较喜欢使用JavaScriptSerializer

• Json.NET
