请教ASP.NET中关于下载的问题

[petercsdn]

在ASP.NET通过以下代码下载文件

Dim filename As String = "aaa.xls"
Dim path As String = Server.MapPath(sDirectory) & filename
Response.Clear()
Response.ContentType = "application/octet-stream"
Response.AddHeader("Content-Disposition", "attachment;FileName=" + HttpUtility.UrlEncode(filename, System.Text.Encoding.UTF8))

Response.WriteFile(path)
Response.End()

当下载对话框出来后,点击保存按钮时，浏览器左下角提示出错，点击浏览器左下角打开明细，里面提示拒绝访问,不知何解？

ASPNET账号没有读file的权限。

And please try:

private void FileDownload(string FullFileName)
{
FileInfo DownloadFile = new FileInfo(FullFileName);
Response.Clear();
Response.ClearHeaders();
Response.Buffer=false;
Response.ContentType="application/octet-stream";
Response.AppendHeader("Content-Disposition","attachment;filename=" +HttpUtility.UrlEncode(DownloadFile.FullName,System.Text.Encoding.UTF8));
Response.AppendHeader("Content-Length",DownloadFile.Length.ToString());
Response.WriteFile(DownloadFile.FullName);
Response.Flush();
Response.End();
}
