使用Response.ContentType = "application/octet-stream" 下载文件，但是保存文件后窗口不关闭？

[jumpding1977]

代码：
HttpContext.Current.Response.Clear()
HttpContext.Current.Response.ClearContent()
HttpContext.Current.Response.ClearHeaders()
HttpContext.Current.Response.ContentType = "application/octet-stream"
sfileName = HttpContext.Current.Request.ServerVariables("SCRIPT_NAME")
sfileName = Mid(sfileName, InStrRev(sfileName, "/") + 1)
If InStr(sfileName, ".") > 0 Then
sfileName = Left(sfileName, InStr(sfileName, ".") - 1)
End If
If InStr(sfileName, "[") > 0 Then
sfileName = Trim(Left(sfileName, InStr(sfileName, "[") - 1))
End If
If sfileName = "" Then sfileName = "unknown"
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename=""" & sfileName & ".txt""")

HttpContext.Current.Response.Write("xxxx")
HttpContext.Current.Response.Write(vbCrLf)

***********************************
浏览器中打开页面，会出现保存文件对话框，有三个按钮【打开】【保存】【取消】。
【打开】【取消】正常，会自动关闭那个空页面。
但【保存】后，空页面还在，如何在保存后自动关闭空页面？

谢谢！！！！

末尾加上：Response.End();

或用這種方式：
private void FileDownload()
{
String FullFileName = Server.MapPath("文件路径");
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();
}

没有用啊，我在最后这样写也没用。

Response.Flush()
Response.Write("<script>window.close();</script>")
Response.End()

"<script>window.close();</script>"居然输出到txt文件中，不是输出到aspx页面html中。
郁闷

不用window.open打开这个页面,而是用链接到这个页面.

[palts520]

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());

打开这个页面时候
<a href="down.aspx" target="_self">下载</a>
target设置成_self试下
