去出差的時候應客戶要求要要將Excel 文件內的數據批量導入到數據庫中，而且有各種不同種類的表格，如果每一個表格多對應一個數據表的話，
按照正常的方法應該是創建數據表，創建數據庫中映射的數據模型，然后數據訪問層，業務層，在為每個表創建一個展示頁面......這樣一套下來花費
的時間多不說在以后客戶又有新的表格需要導入那么是不是也要按照三層的步驟一步一步的來做呢？答案是否定的。這里我向大家介紹一個比較靈活
方式來完成所有的功能，在拓展性上也很好，可以移植到任何程序中使用：
不多廢話直接看程序，程序是最好的解釋：
本程序是通過XML 來保存數據庫字段和需要在界面上顯示的表頭
首先在網站的根目錄下創建一個XML 文件來保存動態生成的數據表以及每一列和表頭對應的中文名：
<?xml version="1.0" encoding="utf-8"?> <DBTable> <table> <CName>任職資格台賬</CName> <EName>rzzgtz</EName> <Identity>R_Id</Identity> <columns> <eColumn eName="xuhao" eType="nvarchar(MAX)" cName="序號" eLength="varchar(10)" /> <eColumn eName="Ztype" eType="nvarchar(MAX)" cName="證書類別" eLength="varchar(10)" /> <eColumn eName="bM" eType="nvarchar(MAX)" cName="部門" eLength="varchar(10)" /> <eColumn eName="Name" eType="nvarchar(MAX)" cName="姓名" eLength="varchar(10)" /> <eColumn eName="Gender" eType="nvarchar(MAX)" cName="性別" eLength="varchar(10)" /> <eColumn eName="CID" eType="nvarchar(MAX)" cName="省份證號" eLength="varchar(10)" /> <eColumn eName="tTemp" eType="nvarchar(MAX)" cName="文化程度" eLength="varchar(10)" /> <eColumn eName="ziwu" eType="nvarchar(MAX)" cName="職務/職稱" eLength="varchar(10)" /> <eColumn eName="fzjg" eType="nvarchar(MAX)" cName="發證機關" eLength="varchar(10)" /> <eColumn eName="XCID" eType="nvarchar(MAX)" cName="證書編號" eLength="varchar(10)" /> <eColumn eName="Qtime" eType="nvarchar(MAX)" cName="取證時間" eLength="varchar(10)" /> <eColumn eName="fTime" eType="nvarchar(MAX)" cName="復審時間" eLength="varchar(10)" /> <eColumn eName="Other" eType="nvarchar(MAX)" cName="備注" eLength="varchar(10)" /> </columns> </table> <DBTable>
DBTable 節點是根節點 內部的table 保存的是數據表中的相關屬性。
節點 <CName></CName>保存的是中文名稱,也是菜單名稱。
節點<EName></EName>保存的是名稱和數據表中的表明一一對應。
節點 <Identity></Identity>保存的是表的主鍵名稱。
節點<columns> </columns> 保存的是數據表中對應的數據列屬性
內部節點 <eColumn eName="xuhao" eType="nvarchar(MAX)" cName="序號" eLength="varchar(10)" />
屬性：eName [數據庫中名稱]，eType[數據類型] cName [表頭名稱] eLength 可有可無的一個屬性
以上是XML 表結構的一些說明;
下面需要一個類來專門操作XML對節點的一些操作和檢索

在有的電腦生進行數據導入 出現未在本地計算機上注冊“microsoft.ACE.oledb.12.0”提供程序 錯誤
處理方法：解決辦法：
去http://download.microsoft.com/download/7/0/3/703ffbcb-dc0c-4e19-b0da-1463960fdcdb/AccessDatabaseEngine.exe下載。
然后安裝就行了。
安裝此插件以后將會支持到office2010 的的文件

以上代碼提供了不同類型的數據綁定 表頭列數據展示列操作列等都有提供。BindType 提供的枚舉對應的綁定列類型
public enum BindType { label, checkbok, editor, delete }
在以上用的的一些約定
特殊類名
| 類名 |
作用 |
出現位置 |
| heck_box |
控制 全選 全部選 |
會出現在dateGridView表頭位置控制整張表的復選框。 |
| CheckBox |
綁定數據主鍵值 |
出現在GridView數據列位置在表頭位置，用來確定數據是否被選中。 |
以上是兩個比較特殊的標簽類名；
特的頁面和特殊的參數：
| 頁面路徑 |
參數 |
作用 |
| InsertInfo.aspx |
cmd:操作指令 [insert,delede,editor] 分別對應增加，刪除 ，編輯功能 eName:數據表對應的英文名 cName:對應的中文名 id:對應的數據主鍵編號 |
添加頁面和編輯頁面為同一個頁面，提供添添加數據錄入界面。 提供加載數據編輯界面。
|
| Ajax/AjaxDateToSql.ashx |
需要傳遞參數同上 |
提供異步處理程序。 提供手動增刪改方法。 |
| 參考： |
href='Ajax/AjaxDateToSql.ashx?cmd=delete&cName=CName&eName=EName&id=id'
InsertInfo.aspx?cmd=editor&cName=CName &eName=EName&id=id' |
|
| 小節 |
cName 和eName 兩個參數貫穿整個程序 為了保證中文表民和數據庫中的表名一致采用雙重驗證 |
|
到了這里已經差不多核心代碼都展示完畢
最后一步做個小結
展示數據

在例中用的了XML 的讀寫檢索，數據拆分，等操作，動態的形成查詢語句，添加語句搜索語句等常用的操作語句，
