namespace DataSet_1
{
    public partial class Form1 : Form
    {
         public Form1()
        {
            InitializeComponent();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            string connectionString = "server=___;uid=___;pwd=___;database=haksa";
            SqlConnection conn = new SqlConnection(connectionString);
            conn.Open();

            string sql = "select hakbun,name,tel from student";
            SqlCommand cmd = new SqlCommand(sql, conn);

            SqlDataAdapter da = new SqlDataAdapter();
            da.SelectCommand = cmd;

            DataSet ds = new DataSet();

            DataTable dt = ds.Tables["student"];
            da.Fill(ds, "t1");
            dataGridView1.DataSource = ds.Tables["t1"];
            conn.Close();
        }
    }
}
