Configurations.Item[Object] Eigenschaft

public:
 property Microsoft::SqlServer::Dts::Runtime::Configuration ^ default[System::Object ^] { Microsoft::SqlServer::Dts::Runtime::Configuration ^ get(System::Object ^ index); };

public Microsoft.SqlServer.Dts.Runtime.Configuration this[object index] { get; }

member this.Item(obj) : Microsoft.SqlServer.Dts.Runtime.Configuration

Default Public ReadOnly Property Item(index As Object) As Configuration

Parameter

Eigenschaftswert

Ein Configuration-Objekt.

Beispiele

Im folgenden Codebeispiel wird die Methode verwendet, um festzustellen, ob die Contains Elementsyntax verfügbar ist. Wenn truedas Codebeispiel die Elementsyntax p.Configurations[0].Name verwendet, um den Namen der Konfiguration abzurufen, die sich an der ersten Position der Auflistung befindet, Indexposition 0.

Beispielausgabe:

Hinweise

Wenn der Aufruf der Methode zurückgegeben wirdtrue, können Sie mithilfe der Syntax Configurations[index]auf das angegebene Element in der Contains Auflistung zugreifen. Wenn die Contains Methode jedoch zurückgibt false, löst diese Eigenschaft eine Ausnahme aus. In C# ist diese Eigenschaft der Indexer für die Configurations-Klasse.
