[C#] connessione

[giuseppe500]

ho creato una oledbconnection chiamata connessione trascinandolo da dati,
mi ignora l'Open e il Close,è come se non ci fossero.
es
chiudo la connessione.
Carico il dataset tramite il data adapter.
non mi da errore!!!!!!!!!!
perchè?
Grazie.

da MSDN:

This implementation of the OleDbDataAdapter opens and closes an OleDbConnection if it is not already open. This can be useful in an application that must call the Fill method for two or more OleDbDataAdapter objects. If the OleDbConnection is already open, you must explicitly call Close or Dispose to close it.
