vs中想要得到单元格第二行第二列，怎么弄啊

SqlConnection cn = new SqlConnection(app);
SqlCommand cmd = cn.CreateCommand();
cmd.CommandText = "select * from Accountnumber where name='admin'";
cmd.CommandType = CommandType.Text;
DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
DataTable dt = new DataTable();
da.Fill(ds);
da.Fill(dt);
MessageBox.Show(ds.Tables[0].Columns[1].ToString());
但是我想得出的是password下面的admin，，不会做，求大神帮助

cmd.Parameters.Add(new SqlParameter("@txt1", txt1));
cmd.CommandText = "select * from student where name=@txt1";
cmd.CommandType = CommandType.Text;
SqlDataAdapter da = new SqlDataAdapter();
DataTable dt = new DataTable();
da.SelectCommand = cmd;
da.Fill(dt);
DataRow dr = dt.Rows[0];
txt_2id.Text = dr[0].ToString();

                                    用datarow（）就可以了

程序得出的结果是password

dt.Rows[i]["xxx"].ToString()

cmd.CommandText = "select [password] from Accountnumber where name='admin'";
string result = cmd.ExecuteScalar().ToString();
