public void Totxt(System.Web.UI.Control ctl, string FileName) { HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312"); //HttpContext.Current.Response.ContentType = "application/ms-excel";application/ms-txt HttpContext.Current.Response.ContentType = "application/ms-txt"; HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + FileName + ".txt"); ctl.Page.EnableViewState = false; System.IO.StringWriter tw = new System.IO.StringWriter(); HtmlTextWriter hw = new HtmlTextWriter(tw); ctl.RenderControl(hw); HttpContext.Current.Response.Write(tw.ToString()); HttpContext.Current.Response.End(); }

protected void button1_click(object sender, eventargs e) { //设定导出文件的格式 response.contenttype = "application/vnd.ms-excel"; //设定编码方式 response.charset = "gb2312"; response.contentencoding = system.text.encoding.utf7; //关闭viewstate enableviewstate = false; stringwriter tw = new stringwriter(); htmltextwriter hw = new htmltextwriter(tw); gridview1.rendercontrol(hw); //把html写回浏览器 response.write(tw.tostring()); response.end(); } 注意要在命名空间中引用using system.io; 在你这个事件后添加如下代码： public override void verifyrenderinginserverform(control control) { } 以上代码已经修改过，将其复制到你的vs里，绝对正确，这可是经过测试过的哟！
