附件下载，中文文件名乱码如何解决？？？

[falleaves]

我写了个程序，里面有文件要作为附件下载，英文文件名都正常，但中文文件名就会乱码，不知道如何解决，望高手指点。

代码如下：
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
Response.Clear();
Response.BufferOutput=true;
Response.Charset="utf-8";//此处用“GB2312”也不行
Response.AppendHeader("Content-Disposition","attachment;filename=测试.xls");
Response.ContentType = "application/vnd.ms-excel";
FileInfo mf=new FileInfo(sFile);
FileStream fs=mf.OpenRead();
Response.WriteFile(fs.Handle,0,mf.Length);
fs.Close();

System.IO.FileInfo file = new System.IO.FileInfo(path);
Response.Clear();
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.UTF8;
// 添加头信息，为"文件下载/另存为"对话框指定默认文件名
Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(name));
// 添加头信息，指定文件大小，让浏览器能够显示下载进度
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "application/octet-stream";
// 把文件流发送到客户端
Response.WriteFile(file.FullName);
// 停止页面的执行
Response.End();

Response.ContentType = "application/octet-stream";
Response.AppendHeader("Content-Disposition", "attachment;filename="
+ HttpUtility.UrlEncode(DownloadFile.Name, System.Text.Encoding.UTF8));

Response.AppendHeader("Content-Length", DownloadFile.Length.ToString());

GB2312也不行么?,实在不行你重新写一下试试

这样写就OK了
Response.AddHeader("Content-Disposition","attachment;filename=" + HttpUtility.UrlEncode(测试.xls));

再给你回复一次,我faint

string pathfile = @"F:\新建文件夹\1.txt"; //pathfile 是要下载的文件名称
System.IO.FileInfo file = new System.IO.FileInfo(pathfile);
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(file.Name));
Response.AddHeader("Content-Length", file.Length.ToString());
Response.ContentType = "application/octet-stream";
Response.WriteFile(file.FullName);
Response.End();
