  }
  int n = 0;
  SqlConnection conn = new SqlConnection(connString);
  SqlCommand cmd = new SqlCommand(sql, conn);
  conn.Open();

DialogResult dlResult = MessageBox.Show(this, "要删除这些记录吗？", "请确认", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
                if (dlResult == DialogResult.Yes)
                {
                    try
  {
  string connString = "Server=10.10.0.5;Database=xianggelia;User Id=sa;Password=12345678;";
