随手记录修改某条记录时，不使用数据库控件而用datareader

可能是很简单的，记录一下，以后自己好用

    protected void Page_Load(object sender, EventArgs e)
    {
        getSession.JuageSession();//自定义的一个检查登录状态的类
        if (!Page.IsPostBack)
        {
            int id =Convert.ToInt32(Request["id"]);
            this.ViewState["id"] = id;
            string sqlexe = "select * from product where id = " + id;
            SQLDbDataReader dr = userSql.db.ExecuteDataReader(sqlexe);
            if (dr.Read())
            {
                this.title.Text = dr["title"].ToString();
                this.content.Value = dr["content"].ToString();
                DropBind(Convert.ToInt32(dr["parent"]));
                this.ViewState["smallimg"] = dr["smallimg"];
                this.ViewState["bigimg"] = dr["bigimg"];
                this.ViewState["id"] = dr["id"];
                this.audit.Checked = Convert.ToBoolean(dr["audit"]);
                this.post.Text = dr["post"].ToString();
                this.comment.Text = dr["comment"].ToString();
            }
            dr.Close();
            dr.Dispose();
            dr = null;
            PageControlInt();

        }
    }
