你是form还是web呀，web的话简单的就是
//Excel
Response.AppendHeader("Content-Disposition", "attachment;filename=temp.xls");
Response.ContentType = "application/ms-excel";
System.IO.StringWriter writer = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWriter = new System.Web.UI.HtmlTextWriter(writer);
this.pnlPrinter.RenderControl(htmlWriter);
//输出
Response.Write(writer.ToString());
Response.End();
