最近項目開發中的傳輸數據是圍繞Remoting而召開的，所以想把所有的數據實體都定義統一的格式，于是就寫了一個基于DataTable的基類BaseModal，其他數據實體全部繼承于它。此BaseModal基類還包括了一些其他的自有的屬性，例如pageSize每頁記錄數、currentPage當前頁碼等等，代碼如下：

273 結果發現數據在放序列化的時候出錯，發現原來是沒有加入序列化和反序列化構造函數，雖然BaseModal繼承于DataTable，并且加入了[Serializable]樹序列化屬性，但是要實現想繼承序列化，還是要加入構造函數，于是加入：
?1protected?BaseModel(SerializationInfo?info,?StreamingContext?context)?:?base(info,?context)#region?protected?BaseModel(SerializationInfo?info,?StreamingContext?context)?:?base(info,?context)
?2????????//?-----------------------------------------------------------------------------------------
?3????????/**////?<summary>
?4????????///?反序列化構造函數
?5????????///?</summary>
?6????????///?<param?name="si">反序列化所需的全部數據</param>
?7????????///?<param?name="context">目標描述</param>
?8????????protected?BaseModel(SerializationInfo?info,?StreamingContext?context)?:?base(info,?context)
?9????????{
10????????}

12????????#endregion

14????????public?override?void?GetObjectData(SerializationInfo?info,?StreamingContext?context)#region?public?override?void?GetObjectData(SerializationInfo?info,?StreamingContext?context)
15????????//?-----------------------------------------------------------------------------------------
16????????/**////?<summary>

19????????///?<param?name="info">序列化所需的全部數據</param>
20????????///?<param?name="context">目標描述</param>
21????????public?override?void?GetObjectData(SerializationInfo?info,?StreamingContext?context)：base.GetObjectData(info,?context)
22????????{
23?????????}
24????????//?-----------------------------------------------------------------------------------------
25????????#endregion
結果編譯，沒有任何錯誤，但是類中的屬性（pageSize等）值卻獲取不到，想了很久，發現其實道理跟前面有些類似，因為自己加入的屬性根本就沒有“告訴”序列化函數去處理，自然而然值就丟失了，于是修改函數如下：
?1protected?BaseModel(SerializationInfo?info,?StreamingContext?context)?:?base(info,?context)#region?protected?BaseModel(SerializationInfo?info,?StreamingContext?context)?:?base(info,?context)
?2????????//?-----------------------------------------------------------------------------------------
?3????????/**////?<summary>
?4????????///?反序列化構造函數
?5????????///?</summary>
?6????????///?<param?name="si">反序列化所需的全部數據</param>
?7????????///?<param?name="context">目標描述</param>
?8????????protected?BaseModel(SerializationInfo?info,?StreamingContext?context)?:?base(info,?context)
?9????????{
10????????????index?=?info.GetInt32("index");
11????????????pageSize?=?info.GetInt32("pageSize");
12????????????currentPage?=?info.GetInt32("currentPage");
13????????????pages?=?info.GetInt32("pages");
14????????????totalRecord?=?info.GetInt64("totalRecord");
15????????????description?=?info.GetString("description");
16????????}

28????????{
29????????????info.AddValue("index",?index);
