Check if SQL Connection is Open or Closed

Question

How do you check if it is open or closed I was using

 if (SQLOperator.SQLCONNECTION.State.Equals(\"Open\"))

however, even the State is \'Op

Answer 1

This code is a little more defensive, before opening a connection, check state. If connection state is Broken then we should try to close it. Broken means that the connection was previously opened and not functioning correctly. The second condition determines that connection state must be closed before attempting to open it again so the code can be called repeatedly.

// Defensive database opening logic.

if (_databaseConnection.State == ConnectionState.Broken) {
    _databaseConnection.Close();
}

if (_databaseConnection.State == ConnectionState.Closed) {
    _databaseConnection.Open();
}
