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.
