Hinweise
ZipPackage ist der Standardpakettyp, der von der Open Methode verwendet wird.
Mit dieser Open Methode wird das Paket mit einem Standardattribute None geöffnet (um ein anderes Attribut anzugeben, verwenden Sie die Open Methodenüberladung).
Weitere Informationen finden Sie in der Opc-Spezifikation (Open Packaging Conventions), die zum Download verfügbar https://www.ecma-international.org/publications-and-standards/standards/ecma-376/ist.
