Pass null Nothing nullptr unit ein NULL-Verweis (Nothing in Visual Basic) for the transaction parameter txn when the SupportsDTCTransactions property is false. If the SupportsDTCTransactions property is true, you can pass null Nothing nullptr unit ein NULL-Verweis (Nothing in Visual Basic) in the transaction parameter to indicate that the container supports transactions, but is not going to participate.

Beispiele

The following code example shows how to add the OLE DB connection to the connection manager and acquire the connection.

// Create the package.
Package pkg = new Package();

// Add a ConnectionManager to the Connections collection.
ConnectionManager connMgr = pkg.Connections.Add("ADO.NET:OLEDB");
connMgr.Properties["RetainSameConnection"].SetValue(connMgr , true);
connMgr.ConnectionString = connStr;

// Aqcuire the connection.
object connection = connMgr.AcquireConnection(null);

' Create the package.
Dim pkg As Package =  New Package() 
 
' Add a ConnectionManager to the Connections collection.
Dim connMgr As ConnectionManager =  pkg.Connections.Add("ADO.NET:OLEDB") 
connMgr.Properties("RetainSameConnection").SetValue(connMgr , True)
connMgr.ConnectionString = connStr
 
' Aqcuire the connection.
Dim connection As Object =  connMgr.AcquireConnection(Nothing)
