【问题描述】：
我正在尝试使用 web.config 连接到 MySQL，并为此使用了 MySQL 网站配置。问题是它使我的网站在运行而不是运行时显示错误。 :D
这是我的 web.config SQL 连接：
<connectionStrings>
<remove name="LocalMySqlServer" />
<add name="LocalMySqlServer" connectionString="password=PASS****;user id=9b443f_users;server=MYSQL5008.myWindowsHosting.com;database=db_9b443f_users" providerName="MySql.Data.MySqlClient" />
</connectionStrings>
<system.web>
