怎么下载文件??

[bhys]

怎么下载文件,文件不是压缩格式.
Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(scfilename, System.Text.Encoding.UTF8))
Response.WriteFile(filepath)
Response.End()
下面的程序有点问题.下载时弹出的信息不正确.下载文本文件时会自动加一串代码进去,怎么解决..

[待接入自我]

呵呵，一个土办法：Response.redirect("......../aa.txt")
不过，文本文件会被打开的，
zip等文件，则会自动弹出windows下载工具

string path = Server.MapPath(Request.Params["File"]);
System.IO.FileInfo file = new System.IO.FileInfo(path);

// clear the current output content from the buffer
Response.Clear();
// add the header that specifies the default filename for the Download/SaveAs dialog
Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
// add the header that specifies the file size, so that the browser
// can show the download progress
Response.AddHeader("Content-Length", file.Length.ToString());
// specify that the response is a stream that cannot be read by the
// client and must be downloaded
Response.ContentType = "application/octet-stream";
// send the file stream to the client
Response.WriteFile(file.FullName);
// stop the execution of this page
Response.End();
