核心代码如下：

            this.drSSFL.DataBind();

            if (Request.QueryString["ID"] != null)
            {
                //显示当前的商品信息
                DataTable tmpda = new DataTable();
                tmpda = DataBase.Get_Table("select * from 紫砂壶信息 where 紫砂壶编号=" + Request.QueryString["ID"]);

                }
            }
        }

    {
        //判断信息是否正确
        if (this.txtZSHMC.Text.Trim() == "")

            Guid tmp = Guid.NewGuid();
            FileName = tmp.ToString() + strHzm;
            FileName1 = DPath + tmp.ToString() + strHzm;
            this.FileTP.PostedFile.SaveAs(FileName1);
            if (Session["imgname"] != null)
            {
                if (File.Exists(DPath + Session["imgname"].ToString()))
                {
