Question

If you need to open a SqlConnection before issuing queries, can you simply handle all non-Open ConnectionStates in the same way? For example:

    if (connection.State != ConnectionState.Open)     {         connection.Open();     } 

I read somewhere that for ConnectionState.Broken the connection needs to be closed before its re-opened. Does anyone have experience with this? Thanks-

Broken connection state does need to be closed and reopened before eligible for continued use.

Edit: Unfortunately closing a closed connection will balk as well. You’ll need to test the ConnectionState before acting on an unknown connection. Perhaps a short switch statement could do the trick.
