Question

我与我的数据库建立了连接，并且我已经执行了一个查询以获取我的表的特定字段的结果，但是读者没有输入，为什么？

 public void connect()
    {
        string connStr = @"Server=xx98.66;Port=xx6;Database=sxxt;Uid=axx;Pwd=admxxx3z;";
        MySqlConnection conn = new MySqlConnection(connStr);

        try
        {
            Console.WriteLine("Connecting to MySQL...");
            conn.Open();

            string stm = "SELECT lastUpdated from soccerseason WHERE caption = 'Eredivisie 2015/1'";
            MySqlCommand cmd = new MySqlCommand(stm, conn);

            MySqlDataReader rdr = cmd.ExecuteReader();

            while (rdr.Read())
            {
                Console.WriteLine("stdrstrr" + rdr.GetString(0));
            }

            Console.WriteLine("Connection successfull !");

            conn.Close();
            Console.ReadLine();
        }
        catch (Exception ex)
        {
            Console.WriteLine("Eccezione =>  " + ex.ToString());
        }
        Console.WriteLine("Done.");
    }
}
