上傳EXCEL並把內容批量寫入指定數據庫

編輯：.NET實例教程

注明：必須按照數據庫字段的“順序”，“字段格式 ”來寫EXCEL；自動編號不要寫入Excel。

我這裡用的是Access

前台代碼：

<%...@ Page language="c#" Codebehind="Excel.ASPx.cs" AutoEventWireup="false" Inherits="TestAll.Excel" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD Html 4.0 Transitional//EN" >

<Html>

<HEAD>

<title>Excel</title>

</HEAD>

<TABLE id="Table1" height="100%"

cellSpacing="1" cellPadding="1" width="100%" border="0">

<TR>

<TABLE id="Table3" cellSpacing="1" cellPadding="1" width="300"

border="0">

<TR>

<TD align="center" colSpan="2">Excel批量上傳</TD>

</TR>

<TR>

<TR>

<TD align="right" colSpan="2">>>表名稱為Excel表格中左下角的字段名</TD>

</TR>

</TABLE>

</TABLE>

</form>
