Voorbeelden

In het volgende voorbeeld worden afzonderlijke taken gestart die een reguliere expressie gebruiken om het aantal woorden in een set tekstbestanden te tellen. De ContinueWhenAll methode wordt gebruikt om een taak te starten die het totale aantal woorden weergeeft wanneer alle antecedente taken zijn voltooid.

De aanroep van de methode van Task.Wait de vervolgtaak staat niet toe dat uitzonderingen worden verwerkt die worden gegenereerd door de antecedent-taken, dus in het voorbeeld wordt de Task.Status eigenschap van elke antecedent-taak onderzocht om te bepalen of de taak is geslaagd.

Opmerkingen

De ContinueWhenAll methode voert de continuationAction gedelegeerde uit wanneer alle taken in de tasks matrix zijn voltooid, ongeacht de voltooiingsstatus.

Uitzonderingen die worden gegenereerd door taken in de tasks matrix, zijn niet beschikbaar voor de vervolgtaak via gestructureerde uitzonderingsafhandeling. U kunt bepalen welke uitzonderingen zijn gegenereerd door de Task.Exception eigenschap van elke taak in de tasks matrix te onderzoeken. Als u gestructureerde uitzonderingsafhandeling wilt gebruiken om uitzonderingen af te handelen die zijn gegenereerd door taken in de tasks matrix, roept u de Task.WaitAll(Task[]) methode aan.

Voorbeelden

In het volgende voorbeeld wordt een annuleringstoken gemaakt dat wordt doorgegeven aan afzonderlijke taken die een reguliere expressie gebruiken om het aantal woorden in een set tekstbestanden te tellen. Het annuleringstoken is ingesteld als een bestand niet kan worden gevonden. De ContinueWhenAll(Task[], Action{Task[]}, CancellationToken) methode wordt gebruikt om een taak te starten die het totale aantal woorden weergeeft wanneer alle antecedente taken zijn voltooid. Als het annuleringstoken is ingesteld, wat aangeeft dat een of meer taken zijn geannuleerd, wordt de AggregateException uitzondering verwerkt en wordt een foutbericht weergegeven.
