26.3. Datenbankverbindungherstellen
Das Herstellen der Verbindung zur Datenbank erfolgt analog zu ADO.NET mit einem AdomdConnection-Objekt, welchem in der Eigenschaft ConnectionString die Serververbindungszeichenfolge übergeben wird. Anschließend wird die Verbindung durch Aufruf der Methode Open geöffnet, wie in dem folgenden Codebeispiel zu sehen:
ADOMD.AdomdConnection adomdConnection = new ADOMD.AdomdConnection(); adomdConnection.ConnectionString = "Data Source=localhost; Initial Catalog=Adventure Works DW 2008"; adomdConnection.Open();
Nachdem Sie die gewünschten Daten abgefragt haben, müssen Sie die Verbindung mit der Anweisung
adomdConnection.Close();
wieder schließen.
