protected void Button1_Click(object sender, EventArgs e)
{
//添加上传框的个数

if (picnum.Text.Trim() != "")
        {
            FileUpload f1;

                f1.ID = "fu" + i.ToString();
                f1.Width = 282;
                Panel1.Controls.Add(f1);
            }
        }
    }
//上传命令

    protected void Button2_Click(object sender, EventArgs e)
    {
        HttpFileCollection hfc = Request.Files;
        string f_Name, f_Size, f_Type;

        for (int i = 0; i <= hfc.Count-1; i++)
        {
            HttpPostedFile hpf = hfc[i];

            f_Name = Path.GetFileName(hpf.FileName);
            f_Size = hpf.ContentLength.ToString();
            f_Type = hpf.ContentType.ToString();

            hpf.SaveAs(Server.MapPath("~/UpFile/" + f_Name.ToString()));
            Response.Write("上传成功！<br>" + f_Name + "<br>" + f_Type + "<br><br>");
        }

}
