Voorbeelden
In het volgende voorbeeld ziet u hoe u de Commit methode (in een afgeleide klasse) gebruikt wanneer u resources toevoegt aan een XpsDocument.

Opmerkingen
Op basis van instellingen van XpsSerializationManager en XpsPackagingPolicy, zoals FontSubsetterCommitPolicies en PackageInterleavingOrder, kan de spoelbewerking van de Commit methode worden uitgesteld totdat het geheel XpsDocument is gesloten.
