Übersicht über WMI-AnbieterWMI Provider Overview

Der Namespace, mit dem die Informationen zu Reporting ServicesReporting Services in den in diesem Thema gezeigten Codebeispielen abgerufen werden, ist der System.Management -Namespace, der in MicrosoftMicrosoft .NET Framework.NET Frameworkgefunden wurde.The namespace used to obtain information about Reporting ServicesReporting Services in the code samples shown in this topic is the System.Management namespace, found in the MicrosoftMicrosoft .NET Framework.NET Framework. Der System.Management -Namespace enthält eine Reihe verwalteter Codeklassen, über die .NET Framework.NET Framework -Anwendungen auf Verwaltungsdaten zugreifen und diese bearbeiten können.The System.Management namespace provides a set of managed code classes through which .NET Framework.NET Framework applications can access and manipulate management information. Weitere Informationen zur Verwendung der Reporting Services-WMI-Klassen mit dem System.Management -Namespace finden Sie unter "Zugriff auf Verwaltungsinformationen mit System.Management" im MicrosoftMicrosoft .NET Framework.NET Framework -SDK.For more information on using the Reporting Services WMI classes using the System.Management namespace, see "Accessing Management Information with System.Managment" in the MicrosoftMicrosoft .NET Framework.NET Framework SDK.

Suchen einer BerichtsserverinstanzFinding a Report Server Instance

Die bevorzugte Art der Suche nach Informationen auf Ihren Berichtsserverinstallationen besteht im Durchlaufen der WMI-Instanzenauflistung.The preferred way of finding information on your report server installations is to enumerate through the WMI instance collection. Im nachstehenden Beispiel sehen Sie, wie Eigenschaften auf jeder Berichtsserverinstanz gesucht werden: Es wird eine Auflistung erstellt, die zum Anzeigen der Eigenschaften immer wieder durchlaufen wird.The example below shows how to find properties on every report server instance by creating a collection, and looping through the collection to display the properties.
