AsaConnection class
Closes a database connection.
void Close( )
IDbConnection.Close
The Close method rolls back any pending transactions. It then releases the connection to the connection pool, or closes the connection if connection pooling is disabled. If Close is called while handling a StateChange event, no additional StateChange events are fired. An application can call Close more than one time.
