asp.net实现 EXCEL数据导入到数据库功能

  在项目中经常要用EXCEL导入数据到数据库,提高工作效率。
  注意:EXCEL中的第一行不能导入。
  下面是源码:
  IntoExcel.aspx:
  [csharp]
  <%@ Page Language="C#" AutoEventWireup="true" CodeFile="IntoExcel.aspx.cs" Inherits="study_IntoExcel" %>
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ".w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html xmlns=".w3.org/1999/xhtml" >
  <head id="Head1" runat="server">
  <title>无标题页</title>
  <script language="javascript" type="text/javascript"><!--
  // <!CDATA[
  function check() {
  var k=//S+/.[xls]/;
  if(!k.test(document.getElementById("fileId")。value))
  {
  alert("只能上次xls格式的文件");
  return false;
  }
  return true;
  }
  // --></script>
  </head>
  <body>
  <form id="form1" runat="server">
  <div>
  <p>
  <asp:FileUpload ID="fileId" runat="server" />
  <asp:Button ID="Button1" runat="server" Text="上传" OnClientClick="return check()" onclick="Button1_Click" /></p>
  </div>
  </form>
  </body>
  </html>

  Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + savePath + ";Extended Properties='Excel 8.0;HDR=YES
  Provider=Microsoft.Jet.OLEDB.4.0;;//连接驱动sat答案
  Data Source=" + savePath + "; // 数据库地址
  Extended Properties='Excel 8.0; // 连接的是Excel8.0
  HDR=YES;// 有两个值:YES/ NO, 这2个值,说了你是否能直接读列名,NO,只可以读下标
  IMEX=1;//解决数字与字符混合时,识别不正常的情况托福答案
  这个读入数据库的方式不是最佳的,应该用office组件
  select * from [Sheet1$] //引用EXCLE文件中sheet1工作表的内容
  OleDB控件用的是OleDb的驱动程序,可以访问各种数据库
  数据库中的字段:
  [sql]
  create table IntoExcel
  (
  Tid int identity(1,1) primary key,
  Tname varchar(50),
  Tage int,
  Taddress varchar(200),
  )
  SQL控件用的是专用的驱动程序,能高效的访问SQL Server数据库
  SQLConnection只能访问SQL Server,而OleDbConnection则可以访问所有数据库。
  如果只是访问SQL Server的话,SQL比OleDb更快。
