我正在尝试检查任何大写字母的字符串。我的代码未显示任何输入的大写字母，可能是“ sss”，“ Sss”，“ SSS”

if [[ "$pass" =~ [^a-zA-Z0-9] ]]
then
   echo "Upper found"
else
   echo "no upper"
fi

        using (MySqlCommand bb = new MySqlCommand("UPDATE  members SET  Begin = 1 WHERE id ='" + uid + "';"))
        {
            bb.Connection = con;
            con.Open();
            using (MySqlCommand fff = new MySqlCommand("UPDATE  members SET  b = 1 WHERE id ='" + uid + "';"))
            {
                fff.Connection = con;
            }
            this.Hide();
            Main main = new Main();
            main.Show();
        }

我正在尝试将两个表,B和Begin更新为当前登录用户(我的uid命令:

  using (MySqlCommand id = new MySqlCommand("SELECT id FROM members WHERE username='" + textBox1.Text + "';"))
                            {
                                id.Connection = con;
                                MySqlDataReader read3 = cmd.ExecuteReader();
                                read3.Dispose();
                                int …
