EXCEL数据导入数据库实例(NPOI)

Default.aspx 页面代码：

引用了：    <script src="../../js/jquery.easyui.min.js" type="text/javascript"></script>

 <form id="fileForm" runat="server" enctype="multipart/form-data" method="post">

 导入EXCEL：<asp:fileupload runat="server" id="upFile"></asp:fileupload><a href="javascript:;"
                class="btn btn-primary" id="btnExelre">导入</a>

</form>

js代码：

  <script type="text/javascript">
        $(function() {
            //提交导入

第一次使用的时候遇到的问题

使用的npoi不支持excel2003以上的版本，所以导入的时候。要选择03的excel数据，

解决办法：使用新的npoi 或者 把excel文件另存为03的
