C#将HTML导出Excel

首先这个不能用ajax 操作，不过我现在讲的这个方法和ajax 的效果一样。

你在你需要导出的页面写个方法

function DaoChu ()
{
　　location.href = "DaoChu.aspx";
}

然后在 DaoChu.aspx 页面的后台Page_Load 中直接写以下代码

 string html = "<table><tr><td>1</td><td>11</td></tr><tr><td>2</td><td>22</td></tr></table>";
                Response.ContentType = "application/force-download";
                Response.AddHeader("content-disposition",
                    "attachment; filename=" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".xls");
                Response.Write("<html xmlns:x="urn:schemas-microsoft-com:office:excel">");
                Response.Write("<head>");
                Response.Write("<META http-equiv="Content-Type" content="text/html; charset=utf-8">");
                string fileCss = Server.MapPath("~/css/daoChuCSS.css");
                string cssText = string.Empty;
                StreamReader sr = new StreamReader(fileCss);
                var line = string.Empty;
                while ((line = sr.ReadLine()) != null)
                {
                    cssText += line;
                }
                sr.Close();
                Response.Write("<style>" + cssText + "</style>");
                Response.Write("<!--[if gte mso 9]><xml>");
                Response.Write("<x:ExcelWorkbook>");
                Response.Write("<x:ExcelWorksheets>");
                Response.Write("<x:ExcelWorksheet>");
                Response.Write("<x:Name>Report Data</x:Name>");
                Response.Write("<x:WorksheetOptions>");
                Response.Write("<x:Print>");
                Response.Write("<x:ValidPrinterInfo/>");
                Response.Write("</x:Print>");
                Response.Write("</x:WorksheetOptions>");
                Response.Write("</x:ExcelWorksheet>");
                Response.Write("</x:ExcelWorksheets>");
                Response.Write("</x:ExcelWorkbook>");
                Response.Write("</xml>");
                Response.Write("<![endif]--> ");
                Response.Write(html);//HTML
                Response.Flush();
                Response.End();

这样就好了，html 代码最好是table里面写，因为EXCEL 其实就是 table 。
