Exemples
L’exemple suivant montre comment utiliser la Commit méthode (dans une classe dérivée) lorsque vous ajoutez des ressources à un XpsDocument.

En fonction des paramètres de XpsSerializationManager et XpsPackagingPolicy, tels que et PackageInterleavingOrder, l’opération de vidage de la Commit méthode peut être retardée jusqu’à ce que FontSubsetterCommitPolicies l’ensemble XpsDocument soit fermé.
