编写下面的代码，运行时提示数据库表名personlike无效，应该是哪里出现问题了呢？
 protected void Page_Load(object sender, EventArgs e)
        {
            SqlConnection con = db.createconnection();
            con.Open();
            SqlCommand cmd = new SqlCommand("select * from personlike",con);
            SqlDataReader sdr = cmd.ExecuteReader();            this.CheckBoxList1.DataTextField = "likeContent";
            this.CheckBoxList1.DataValueField = "id";
            this.CheckBoxList1.DataSource = sdr;
            this.CheckBoxList1.DataBind();
            sdr.Close();
            con.Close();
        }
红色行为错误提示行

SqlDataReader 不是这么用的
while(sdr.Read())
{
逐条记录读取
}
自己网上查查他们的用法就知道了

谢谢！
