你用下面的方法试一下 1. if you are using code behind, make AutoEventWireup=false in your aspx page2. make sure you don't have ButtonViewAttachment_Click hooked up in two places, i.e., once in the aspx, once in InitComponents3. also, call Response.Clear() private void ButtonViewAttachment_Click(object sender, System.EventArgs e) { if(null==this.DropDownListAttachments.SelectedItem) return; Response.Clear(); this.Response.AppendHeader("Content-Disposition","attachment;filename="+this.DropDownListAttachments.SelectedItem.Text.Trim()); this.Response.Charset ="UTF-8"; this.Response.ContentEncoding =System.Text.Encoding.Default; this.Response.WriteFile(this.Attachments.AbsolutePath(this.DropDownListAttachments.SelectedItem.Text.Trim())); this.Response.End(); }4. by the way, it is a bad idea to output the file in the same aspx, consider to use a separate page instead
Response.Clear();
this.Response.AppendHeader("Content-Disposition","attachment;filename="+文件名称);
this.Response.Charset ="UTF-8";
this.Response.ContentEncoding =System.Text.Encoding.Default;
this.Response.WriteFile(this.Attachments.AbsolutePath(this.DropDownListAttachments.SelectedItem.Text.Trim()));
this.Response.End();

下载的程序放在另外单独的页面的page_load里。 如download.aspx本页加一个iframe 每次下载的时候，传个id 号过去就可以了设iframe.src = download.aspx?id = idnumber
Response.ClearContent();
Response.Clear();
//文件流输出
Response.AppendHeader("Content-Disposition", "attachment;filename=" + strDisplayname);
Response.ContentType = "application/octet-stream";
this.Response.Charset = "UTF-8";
this.Response.ContentEncoding =System.Text.Encoding.Default;
Response.BinaryWrite(DocBuffer);
//结束文件流输出
Response.End();还是要弹出两次.是不是我分帧的缘故?而且在弹出第一个窗口的时候,后面没有下载窗口(也就是下载对话框:有估计剩余时间,下载到..等等的信息的窗口),点击打开又弹出一样的窗口后面有个下载窗口.但是点击保存的话,窗口就不会再弹出来了.我在后台跟踪的时候,代码是运行一遍的,而且到了Response.End();的时候就抛出异常({"线程正被中止。" })
{
if(!Page.IsPostBack)
{
string strFileName ="";
strFileName = Request.QueryString["FILE_NAME"].ToString();
strFileName = HttpUtility.UrlEncode(System.Text.Encoding.UTF8.GetBytes(strFileName));
Response.Clear();
Response.ContentType = "application/x-msexcel";
Response.AddHeader("Content-Disposition", "inline; filename="+strFileName);
System.IO.FileStream MyFileStream =new FileStream(Request.QueryString["REPORT_FILE"].ToString(),System.IO.FileMode.Open,System.IO.FileAccess.Read,System.IO.FileShare.Read);
long FileSize = MyFileStream.Length;
byte[] Buffer = new byte[(int)FileSize];
MyFileStream.Read(Buffer, 0, (int)FileSize);
MyFileStream.Close();
Response.BinaryWrite(Buffer);
}
}
catch(Exception exp)
{
Response.Write("导出数据错误!");
}
在前面一个页面完成数据填入工作并调用上面页面:string Buffer = this.theucExportExcelLogic.SetDataToExcel(this._ExportData, this._ExportHeaderData, strFileName,this._HeaderType, this._OnlyVisible);
Response.Clear();
Response.Redirect("../../ExportExcel/ShowReport.aspx?REPORT_FILE=" + Buffer+"&FIlE_NAME="+this._OutFileName ,true);
aaaa页面bb.htm
bbbb页面kk.htm
<HTML><body>
<iFrame id="iframe" with=100px height=100px src="aa.htm"></iFrame>
<script language="javascript">iframe.document.location.href="bb.htm"</script>
</body></HTML>运行会看到 bbbb.
<iframe name="iframe" width="1" height="1" src='Download.aspx' frameborder="0" runat="server" ID="Iframe1">.aspx.cs
if(!this.Page.IsStartupScriptRegistered("dgscript"))
