ASP.net中导出Excel的简单方法介绍

下面介绍一种ASP.net中导出Excel的简单方法

先上代码：前台代码如下（这是自己项目里面写的一点代码先贴出来吧）

<div id="export" runat="server" style="width: 700px; margin-left: auto; margin-right: auto;">
<!--startprint-->

<table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" style="word-break: break-all;">

<tr>

<td align="center" colspan="7" valign="middle" style="font-size: 14px; font-family: 宋体; font-weight: bold;

height: 30px">

<span id="spanYEAR" runat="server"></span>年<span id="spanMONTH" runat="server"></span>月分公司月度需求生产任务汇总

</td>

</tr>

<tr>

<td align="right" valign="middle" colspan="7">

<table width="100%">

<tr>

<td colspan="2" align="left">

&nbsp;数量单位：支

</td>

<%-- <td width="10%" align="center" style="font-weight: bold;">

&nbsp;

</td>--%>

<td width="20%" align="center" style="font-weight: bold;">

</td>

<td width="25%" colspan="2" align="center">

</td>

<td width="40%" colspan="2" align="center">

</td>

</tr>

</table>

</td>

</tr>

</table>

<table width="100%" border="0" align="center" cellpadding="0" cellspacing="0" style="font-size: 12px;

font-family: 宋体; word-break: break-all;">

<tr>

<td colspan="4" align="left" valign="top">

<div id="div" runat="server">

<table width="100%" border="1" align="center" cellpadding="0" cellspacing="0" style="font-family: 宋体;

word-break: break-all;">

<tr>

<td width="8%" align="center" style="font-weight: bold; height: 25px">

</tr>

<asp:Repeater ID="rptXQPC" runat="server">

<td width="15%" align="center">

<td width="15%" align="center">

<%#Eval("Fourth")%>

</td>

</tr>

</ItemTemplate>

</asp:Repeater>

<tr>

<td colspan="3" width="40%" align="right" style="font-weight: bold; height: 25px">

批次合计：

</td>

<td width="15%" align="center" style="font-weight: bold;">

<div id="divFirst" runat="server"></div>

</td>

<td width="15%" align="center" style="font-weight: bold;">

<div id="divSecond" runat="server"></div>

</td>

<td width="15%" align="center" style="font-weight: bold;">

<div id="divThird" runat="server"></div>

</td>

<td width="15%" align="center" style="font-weight: bold;">

<div id="divFourth" runat="server"></div>

</td>

</tr>

</table>

</div>

</td>

</tr>

</table>

<!--endprint-->

</div>

后台代码如下 ：

绑定Repeater数据这里接就不多做介绍了（用的Repeater嵌套）

下面贴出后台导出Excel的方法：

/// <summary>

/// 将数据导出到excel，与下面的函数同时使用才能正常工作

/// </summary>

/// <param name="ctl"></param>

public void ToExcel(System.Web.UI.Control ctl)

{

HttpContext.Current.Response.Clear();

HttpContext.Current.Response.Charset = "";

string filename = "Report" + System.DateTime.Now.ToString("_yyyyMMddHHmm");

HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" +

System.Web.HttpUtility.UrlEncode(filename, System.Text.Encoding.UTF8) + ".xls");

HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;

HttpContext.Current.Response.ContentType = "application/ms-excel";//image/JPEG;text/HTML;image/GIF;vnd.ms-excel/msword

ctl.Page.EnableViewState = false;

System.IO.StringWriter tw = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);

ctl.RenderControl(hw);

HttpContext.Current.Response.Write(tw.ToString());

HttpContext.Current.Response.End();

}

后台导出Excel时直接调用为 ToExcel(this.export); 这里的export是加了runat="server"的div名称，

这句代码的意思是调用ToExcel的方法导出export里面的页面数据（页面上的数据是怎么展示的，导出来以后的Excel数据会以同样的方式展示）
