aspx导出文件

System.IO.StringWriter sw = new System.IO.StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
// reptype.RenderControl(htw);//reptype为要导出的对象,当前是reptype,如果是DataGrid,DataList等都可以
Response.Buffer = true;
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.ContentType = "Response.ContentType";//Response.ContentType是输出流的 HTTP MIME 类型
//Response.ContentType --- word文件
//application/vnd.ms-excel --- excel文件
Response.Charset = "utf-8";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode("试卷", System.Text.Encoding.UTF8) + ".doc");
//attachment --- 作为附件下载
//inline --- 在线打开
//filename如果是中文,则可以用HttpUtility.UrlEncode(fileName,System.Text.Encoding.UTF8)进行进行编码,以解决文件名乱码的问题

Response.Write("aa"+"\n"+"sd");
Response.Flush();
Response.Close();
