who can give me a example for asp multiple files upload?

<Script Language="C#" Runat="Server">
public void DoUpload(Object src,EventArgs e)
{
//取得上传文件的个数
int FileCount = Request.Files.Count;
string strFilename;
string[] AFilename;
char[] de = {'\\'};
HttpPostedFile hpf; for(int i=0;i<FileCount;i++)
{
hpf = Request.Files[i];

AFilename = hpf.FileName.Split(de);
strFilename = AFilename[AFilename.Length-1];
Response.Write(strFilename);
hpf.SaveAs(Server.MapPath(".")+"\\"+strFilename);
//在Panel控件中显示上传过程
AddPanelControls(strFilename);
}
}public void AddPanelControls(string filename)
{
Label lblShow = new Label();
lblShow.Text = filename+"已经上传<br>";
Panel1.Controls.Add(lblShow);
}
</script>
