It is an another method.
In same way you can do this in asp.net.

C#

string cmd="select *from Admin where ID='"+txtFilenO.Text+"' and Password='"+textBox1.Text+"' ";
            SqlCommand cmd1 = new SqlCommand(cmd,Db.GetConnection());
            SqlDataReader dr = cmd1.ExecuteReader();
            if (dr.Read())
            {
                AdminMenu n = new AdminMenu();
                n.lblsser.Text = dr[0].ToString();
                n.Show();
                this.Dispose();
                this.Close();
                cmd1.Connection.Close();
               
            }
            else
            {
                cmd1.Connection.Close();
                MessageBox.Show("ID/Password is not valid");
            }
