    class Program
    {
        static void Main(string[] args)
        {
            string connSting;
            connSting = "server=localhost;database=student;Integrated Security=True ";
            SqlConnection sConn = new SqlConnection(connSting);
            try
            {

            }
            catch (Exception ex)
            {
                Console.WriteLine("链接错误:" + ex.Message);
            }
            string sqlMessage=null;

            SqlCommand sCmd = new SqlCommand(sqlMessage, sConn);

            SqlDataReader sdr = null;
            try
            {
                sdr = sCmd.ExecuteReader();

                Console.WriteLine(" 姓名   性别   年龄 ");
                while (sdr.Read())
                {
                    Console.WriteLine(sdr["name"] +""+ sdr["sex"]+"" + sdr["age"]);

            }
            catch (Exception ex)
