.NET Oject And Json

　　在最近的項目開發中，需要將.NET 對象序列化為Json字串，傳遞到用戶端瀏覽器，同時，需要將用戶端的Json字串傳遞到Server,還原序列化為.NET對象，主要有三種方式：

• 　　DataContractJsonSerializer

　　序列化：

/// <summary>
/// 將.NET對象序列化為Json
/// </summary>
/// <typeparam name="T">.NET物件類型，此處為泛型</typeparam>
/// <param name="obj">.NET對象</param>
/// <returns>返回Json字串</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;
        }

　　還原序列化：

/// <summary>
/// 將Json還原序列化為.NET對象
/// </summary>
/// <typeparam name="T">.NET物件類型</typeparam>
/// <param name="json">序列化字串</param>
/// <returns>返回.NET對象</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>
/// 將.NET對象序列化為Json
/// </summary>
/// <typeparam name="T">.NET物件類型，此處為泛型</typeparam>
/// <param name="obj">.NET對象</param>
/// <returns>返回Json字串</returns>
        public static string Serialize<T>(T obj)
        {
            System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
return serializer.Serialize(obj);
        }

　　還原序列化：

 /// <summary>
/// 將Json還原序列化為.NET對象
/// </summary>
/// <typeparam name="T">.NET物件類型</typeparam>
/// <param name="json">序列化字串</param>
/// <returns>返回.NET對象</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);
        }

　　我還是比較喜歡使用JavaScriptSerializer

• Json.NET
