// 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)
