C#

DataSet ds = new DataSet();
                        SqlDataAdapter da = new SqlDataAdapter("select * from Admin_Login where username ='" + txtusername.Text + "' and password='" + txtpassword.Text + "'", sconn);
                        da.Fill(ds);
                        int count = ds.Tables[0].Rows.Count;
                        if (count == 0)
                        {
                            MessageBox.Show("Wrong username or password");
                            
                            txtusername.Focus();

                        }
                        else
                        {
                            successpage pg= new successpage ();
                            pg.Show();
                            this.Hide();
                        }
                        sconn.Close();
