Hinweise
Verwenden Sie die ConfigurationSectionCollection -Klasse, um eine Auflistung von ConfigurationSection -Objekten zu durchlaufen. Sie können mit der -Eigenschaft oder der Sections -Eigenschaft auf diese Auflistung von Sections -Objekten zugreifen.
Die ConfigurationSectionCollection -Klasse wird auch bei der Erstellung von benutzerdefinierten Typen verwendet, die die ConfigurationSection -Klasse erweitern.
Eigenschaften
| Count |
Ruft die Anzahl der Abschnitte in diesem ConfigurationSectionCollection-Objekt ab. |
| Count |
Ruft die Anzahl von Schlüssel-Wert-Paaren in der NameObjectCollectionBase-Instanz ab. (Geerbt von NameObjectCollectionBase) |
