Hinweise

ASP.NET Integritätsüberwachung ermöglicht es Produktions- und Betriebsmitarbeitern, bereitgestellte Webanwendungen zu verwalten. Der System.Web.Management Namespace enthält die Integritätsereignistypen, die für das Packen von Anwendungsstatusdaten und die Anbietertypen, die für die Verarbeitung dieser Daten verantwortlich sind. Es enthält auch unterstützende Typen, die während der Verwaltung von Integritätsereignissen helfen.

Die WebBaseEventCollection Klasse wird verwendet, um eine Sammlung von Integritätsüberwachungsereignissen an Anbieter wie die .SqlWebEventProvider
