前些天写项目的时候，客户要求用HTML表格把信息展示出来，后面还要用展示的内容要导出Excel。本来想想在后台操作的话估计是要做死了，但是经过细想，Excel能够发布成HTML,一定也可以由HTML转成Excel。经过几次搜索，算是把问题完善解决了代码如下（不能用Ajax调用来完成，因为Ajax不会刷新页面）:
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\">");
#region 样式的读取
string fileCss = Server.MapPath("~/Content/CalCSS/tableCss.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>");
#endregion
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(strHtml1);//这里是前台页面的HTML
Response.Flush();
Response.End();
经过测试能够完全的展示页面的样式和规格：
