    前台:

    <form id="form1" runat="server">
        <div>
            <asp:Panel ID="Panel1" runat="server" Width="125px">
                <asp:FileUpload ID="fu" runat="server" Width="282px" /></asp:Panel>
            <asp:TextBox ID="picnum" runat="server" Width="25px"></asp:TextBox>
            <asp:Button ID="Button1" runat="server" Text="修改数量" OnClick="Button1_Click" />
            <asp:Button ID="Button2" runat="server" Text="上传图片" OnClick="Button2_Click" /></div>
    </form>

    后台:

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

    if (picnum.Text.Trim() != "")
            {
                FileUpload f1;
                for (int i = 0; i < Convert.ToInt16(picnum.Text)-1; i++)
                {
                    f1 = new FileUpload();
                    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>");
            }

        }
