主要解决Excel导入数据库

页面上的JS脚本 判断浏览器 选择文件的绝对路径 

<script type="text/javascript">
            function checkFile()
            {
                //判断浏览器类型
                var isIE = (document.all) ? true : false;
                var isIE7 = isIE && (navigator.userAgent.indexOf('MSIE 7.0') != -1);
                var isIE8 = isIE && (navigator.userAgent.indexOf('MSIE 8.0') != -1);
         
                var file=document.getElementById("FileUpload1");
                var path=file.value;
                
                if(isIE7 || isIE8)
                {
                    file.select();
                    path=document.selection.createRange().text;
                    document.selection.empty();
                }
               document.getElementById("txtFilePath").value=path;
            }
            function checkNull()
            {
               var path=document.getElementById("txtFilePath").value;
               if(path=="" ||path==null)
               {
                alert('请选择要上传的文件!');
                return false;
               }
               return true;
            }
        </script> 

  网页中需要如下控件：

<asp:FileUpload ID="FileUpload1" runat="server" onchange="checkFile()" />

<input type="hidden" id="txtFilePath" runat="server" />

后台导入：

/// <summary>
   /// Excel导入数据库操作确认
   /// </summary>
   /// <param name="sender"></param>
   /// <param name="e"></param>
    protected void Button2_Click(object sender, EventArgs e)
    {
        string str = txtFilePath.Value.Trim(); ///JS脚本实现获取文件的绝对路径
        ///string str = FileUpload1.PostedFile.FileName;///IE6以前版本获取文件路径字符串
        ///Excel表插入数据库操作语句
        string strInsert = "insert into Student select StuId,StuPwd,StuName,StuZhuanYe ,StuCardId,TeaName "+
                           "from OPENROWSET('MICROSOFT.JET.OLEDB.4.0','Excel 8.0;IMEX=1;HDR=YES;DATABASE="+ str +"',[Sheet1$])";
