CallbackBehaviorAttribute.IncludeExceptionDetailInFaults Eigenschaft

public:
 property bool IncludeExceptionDetailInFaults { bool get(); void set(bool value); };

public bool IncludeExceptionDetailInFaults { get; set; }

member this.IncludeExceptionDetailInFaults : bool with get, set

Public Property IncludeExceptionDetailInFaults As Boolean

Eigenschaftswert

true, wenn nicht behandelte Ausnahmen als SOAP-Fehler zurückgegeben werden sollen, andernfalls false. Der Standardwert ist false.

Beispiele

Das folgende Codebeispiel zeigt ein CallbackBehaviorAttribute für ein Rückrufobjekt, das das SynchronizationContext-Objekt zur Bestimmung des Threads für das Marshallen, die ValidateMustUnderstand-Eigenschaft zum Erzwingen der Nachrichtenvalidierung und die IncludeExceptionDetailInFaults-Eigenschaft zum Zurückgeben von Ausnahmen als FaultException-Objekte zu Debuggingzwecken an den Dienst verwendet.

Hinweise

Legen Sie IncludeExceptionDetailInFaults auf true fest, um zu ermöglichen, dass Ausnahmeinformationen (sofern möglich) zu Debuggingzwecken wieder an die Dienste übermittelt werden. Dies ist eine reine Entwicklungsfunktion, die nicht in bereitgestellten Diensten eingesetzt werden sollte. Diese Fehler werden dem aufrufenden Dienst als FaultException-Objekte angezeigt.
