如何使用asp.net C＃下载HTML表格到Excel文件

问题描述

我有一个HTML表这样：

I have an Html table as such:

<table cellpadding="0" cellspacing="0" border="0" class="Messages" id="idTbl" runat="server">
    <tr>
        <th>date</th>
        <th>Subject</th>
    </tr>
    <tr class="myHot_smsMessages_new">
        <td>01/01/2014</td>
        <td>Some Subject No 1</td>
    </tr>
    <tr class="myHot_smsMessages_new">
        <td>10/12/2013</td>
        <td>Some subject no 2</td>
    </tr>
</table>

和服务器端：

protected void ExportToXLS(object sender, EventArgs e)
{
    Response.ContentType = "application/x-msexcel";
    Response.AddHeader("Content-Disposition", "attachment; filename=ExcelFile.xls"); Response.ContentEncoding = Encoding.UTF8;
    StringWriter tw = new StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(tw); idTbl.RenderControl(hw);
    Response.Write(tw.ToString());
    Response.End();
}

任何想法？

推荐答案

所以我想通了两个解决方案，第一个是从我的网页重定向到一个通用处理器（发送字节流），并在处理程序做一些像user3851829建议以下

So I figured out two solutions, the first one is redirecting from my page to a generic handler (send the ByteStream) and in the handler do something like user3851829 suggested below

我所做的是类似的东西是什么，只是我从一个中继器的内容，然后渲染它放到StringBuilder这样：

What I did was something similar, only I took the content from a repeater and then rendered it into the stringBuilder as such:

protected void ExportToXLS(object sender, EventArgs e)
{
    Response.Clear();
    Response.Buffer = true;
    Response.AddHeader("content-disposition", "attachment;filename=Notifications.xls");
    Response.Charset = "";
    Response.ContentType = "application/vnd.ms-excel";

    using (StringWriter sw = new StringWriter())
    {
        HtmlTextWriter tw = new HtmlTextWriter(sw);

        repeaterID.DataSource = Session["SomeDataFromSession"] as List<SomeObject>;
        repeaterID.DataBind();

        rptNotifications.RenderControl(tw);

        Response.Output.Write(sw.ToString());
        Response.Flush();
        Response.End();
    }
}

这两个答案都在！
