SynchronizationOption-Enumeration

Gibt den Typ der von der Komponente angeforderten automatischen Synchronisierung an.

Namespace: System.EnterpriseServices
Assembly: System.EnterpriseServices (in system.enterpriseservices.dll)

Syntax

'Declaration
<SerializableAttribute> _
Public Enumeration SynchronizationOption
'Usage
Dim instance As SynchronizationOption

[SerializableAttribute] 
public enum SynchronizationOption

[SerializableAttribute] 
public enum class SynchronizationOption

/** @attribute SerializableAttribute() */ 
public enum SynchronizationOption

SerializableAttribute 
public enum SynchronizationOption

Member

	Membername	Beschreibung
	Disabled	COM+ ignoriert beim Bestimmen des Kontexts für das Objekt die Synchronisierungsanforderungen der Komponente.
	NotSupported	Ein Objekt mit diesem Wert nimmt unabhängig vom Status seines Aufrufers nie an einer Synchronisierung teil. Diese Einstellung ist nur für nicht transaktionale Komponenten verfügbar, die keine JIT (Just-in-Time)-Aktivierung verwenden.
	Required	Stellt sicher, dass alle aus der Komponente erstellten Objekte synchronisiert werden.
	RequiresNew	Ein Objekt mit diesem Wert muss an einer neuen Synchronisierung teilnehmen, in der Kontexte und Apartments durch COM+ stellvertretend für alle am Aufruf beteiligten Komponenten verwaltet werden.
	Supported	Ein Objekt mit diesem Wert nimmt an der Synchronisierung teil, sofern vorhanden.

Beispiel

Im folgenden Codebeispiel wird die Verwendung des SynchronizationOption-Typs veranschaulicht.
