上传多个文件:

<Script Language="c#" Runat="Server" >
public void DoUpload (Object src,EventArgs e)
{
int FileCount=Request.Files.Count;
String Uploadfilename;
String[] AFilename;
char[] de={'\\'};
for (int i=0;i<FileCount ;i++ )
{
HttpPostedFile hpf=Request.Files[i];
AFilename=hpf.FileName.Split(de);
Uploadfilename=AFilename[AFilename.Length-1];
hpf.SaveAs(Server.MapPath(".")+"\\"+Uploadfilename);
AddPanelControls(Uploadfilename);

}
}
public void AddPanelControls(String filename)
{
Label lblShow=new Label();
lblShow.Text=filename+"已经上传的文件<br/>";
Panel1.Controls.Add(lblShow);
}
</script>

我想做出类似outlook同时添加多个附件的形式，请问该如何实现？并且用户在其他页面查询上传附件时，只能看到他上传的附件，这种控制又如何实现?

用几个file控件,在服务器端运行
然后
private void Button1_Click(object sender, System.EventArgs e)
{
this.File1.PostedFile.SaveAs("D:\\a1.doc");
this.File2.PostedFile.SaveAs("D:\\a2.doc");
}
