求助 在下载的时候为什么中文的名字变成了乱码？

[byj0066]

destFileName是一个路径和文件名的字符串；

FileInfo fi = new FileInfo(destFileName);
Response.Clear();
Response.ClearHeaders();
Response.Buffer = false;
Response.Charset="GB2312";
Response.ContentEncoding=System.Text.Encoding.GetEncoding("GB2312");
Response.AppendHeader("Content-Disposition","attachment;filename=" + System.Web.HttpUtility.UrlEncode(fi.Name,System.Text.Encoding.Default ));

Response.AppendHeader("Content-Length",fi.Length.ToString());
Response.ContentType="application/octet-stream";
Response.WriteFile(destFileName);
Response.Flush();
Response.End();


以上代码有什么问题吗？为什么我总是出现乱码？System.Text.Encoding.UTF8 也试过了，不可以啊

Response.WriteFile( System.Web.HttpUtility.UrlEncode( destFileName ) );

文件是能打开的，就是默认的文件名是乱码，真是没办法啊

你的那个我改了一下，结果出错了，不可以啊
它说：The path is too long after being fully qualified. Make sure path is less than 260 characters.

设置web.config中：
<globalization
requestEncoding="gb2312"
responseEncoding="gb2312"
/>
