在以下按钮单击事件中实现：private void btnMIME_Click(object sender, System.EventArgs e){ BindData(); Response.ContentType = "application/vnd.ms-excel"; Response.AddHeader("Content-Disposition", "inline;filename=" + HttpUtility.UrlEncode("下载文件.xls",Encoding.UTF8 ) ); //如果输出为Word，修改为以下代码 //Response.ContentType = "application/ms-word" //Response.AddHeader("Content-Disposition", "inline;filename=test.doc") StringBuilder sb=new StringBuilder(); System.IO.StringWriter sw = new System.IO.StringWriter(sb); System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(sw); sb.Append("<html><body>"); dgShow.RenderControl(hw); sb.Append("</body></html>"); Response.Write(sb.ToString()); Response.End();}注：1.若DataGrid中有按钮列，则在导出前应先将其隐藏. 2.若DataGrid有分页，而又要打印所有数据的话就应先取消分页.
