Remarks

The following are allowed state changes:

  • From Closed to Open, using the Open method.

  • From Open to Closed, using either the Close or Dispose method.

Calling the State property on an open connection increases application overhead because each such call causes a SQL_ATTR_CONNECTION_DEAD call to the underlying ODBC driver to determine whether the connection is still valid.
