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>");
        }

    }
