Waarde van eigenschap
De verzameling vermeldingen die zich momenteel in het zip-archief bevinden.
Uitzonderingen
Het zip-archief biedt geen ondersteuning voor lezen.
Het zip-archief is verwijderd.
Het zip-archief is beschadigd en de vermeldingen kunnen niet worden opgehaald.
Voorbeelden
In het volgende voorbeeld ziet u hoe u een zip-archief opent en de verzameling vermeldingen doorloopt.

// Ensures that the last character on the extraction path
// is the directory separator char.
// Without this, a malicious zip file could try to traverse outside of the expected
// extraction path.
if (!extractPath.EndsWith(Path.DirectorySeparatorChar.ToString(), StringComparison.Ordinal))

Opmerkingen
Gebruik de Entries eigenschap om de hele verzameling vermeldingen op te halen. Gebruik de GetEntry methode om één vermelding op naam op te halen.
