Any open connections are not automatically closed when an exception is thrown. If
|
||
|
|
the client application determines that the exception is fatal, it should close any open
|
||
|
|
<see cref="MySqlDataReader"/> objects or <see cref="MySqlConnection"/> objects.

and then displays the exception.
