                    //添加小类别
                    DataTable tmpda1 = new DataTable();
                    tmpda1 = DataBase.Get_Table("select * from 紫砂壶分类 where 上级分类编号='" + tmpda.Rows[i]["分类编号"].ToString() + "'");

以下是引用片段:

核心代码如下:
     protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            if (Session["User"]!= null)
            {

                this.loginout.Style.Add("display","block");
                this.btnUpdate.Visible = true;
            }
            else
            {
                this.loginin.Style.Add("display","block");
                this.btnUpdate.Visible = false;
            }
            //拼合商品类别字符串
            DataTable tmpda = new DataTable();
            if (Request.QueryString["LX"] != null)
            {
                switch (Request.QueryString["LX"])
                {
                    case "QX":
                        tmpda = DataBase.Get_Table("select * from 紫砂壶分类 where 所属类型='器形' and 上级分类编号 is null ");
                        break;
                    case "ZX":
                        tmpda = DataBase.Get_Table("select * from 紫砂壶分类 where 所属类型='局部造型' and 上级分类编号 is null ");
                        break;
                    case "ZSYJ":
                        tmpda = DataBase.Get_Table("select * from 紫砂壶分类 where 所属类型='装饰研究' and 上级分类编号 is null ");
                        break;
                    case "SLYJ":

            }
            else
            {
                tmpda = DataBase.Get_Table("select * from 紫砂壶分类 where 所属类型='器形' and 上级分类编号 is null ");
            }
            if (tmpda.Rows.Count > 0)
            {
                strSplb = "";
                for (int i = 0; i < tmpda.Rows.Count; i++)
