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();
