Hinweise
Konfigurationseinstellungen werden in einer Hierarchie von Konfigurationsdateien gespeichert. Die Configuration Klasseninstanz stellt die zusammengeführte Ansicht der Konfigurationseinstellungen aus allen Konfigurationsdateien dar, die für eine bestimmte physische Entität gelten, z. B. einen Computer, oder für eine logische Entität, z. B. eine Anwendung oder eine Website. Die logische Entität kann auf dem lokalen Computer oder auf einem Remoteserver vorhanden sein. Informationen zu Konfigurationsdateien finden Sie unter Konfigurieren von Apps und ASP.NET Konfigurationsdateien.
Wenn für eine angegebene Entität keine Konfigurationsdatei vorhanden ist, stellt das Configuration -Objekt die Standardkonfigurationseinstellungen dar, die in der Machine.config-Datei definiert sind.
Sie können ein Configuration -Objekt mithilfe der folgenden Klassen abrufen:
Die ConfigurationManager -Klasse, wenn Ihre Entität eine Clientanwendung ist.
Die WebConfigurationManager -Klasse, wenn Ihre Entität eine Webanwendung ist.
Die Namen der Methoden, die ein Configuration Objekt zurückgeben, beginnen mit "Open".
Sie können auch eine Konfigurationsdatei generieren, die die Konfigurationseinstellungen in einem Configuration -Objekt darstellt. Hierzu können Sie eine der folgenden Methoden verwenden:
Rufen Sie die Save -Methode auf, um eine neue Konfigurationsdatei zu erstellen.
Rufen Sie die SaveAs -Methode auf, um eine neue Konfigurationsdatei an einem anderen Speicherort zu generieren.
Die Namen der Methoden, die Konfigurationsdateien erstellen, beginnen mit "Speichern".
Hinweis
Verwenden Sie das Befehlszeilentool Aspnet_regiis, um den Zugriff auf Konfigurationseinstellungen auf einem Remotecomputer zu aktivieren. Weitere Informationen zu diesem Tool finden Sie unter ASP.NET IIS-Registrierungstool (Aspnet_regiis.exe). Informationen zum Erstellen und Zugreifen auf benutzerdefinierte Konfigurationseinstellungen mit Ausnahme der in .NET Framework enthaltenen systeminternen Abschnitte finden Sie unter ConfigurationSection.
Hinweise für Vererber
Die Configuration -Klasse bietet programmgesteuerten Zugriff zum Bearbeiten von Konfigurationsdateien. Sie verwenden eine der "Open"-Methoden, die von der WebConfigurationManager -Klasse für Webanwendungen oder von der ConfigurationManager -Klasse für Clientanwendungen bereitgestellt werden. Diese Methoden geben ein Configuration -Objekt zurück, das wiederum die Methoden und Eigenschaften bereitstellt, die die zugrunde liegenden Konfigurationsdateien behandeln. Sie können auf diese Dateien zugreifen, um Konfigurationsinformationen zu lesen oder zu schreiben.
Sie verwenden die GetSection(String) -Methode oder die GetSectionGroup(String) -Methode, um Konfigurationsinformationen zu lesen. Beachten Sie, dass der Benutzer oder Der Prozess, der liest, über die folgenden Berechtigungen verfügen muss:
Leseberechtigung für die Konfigurationsdatei auf der aktuellen Konfigurationshierarchieebene.
Leseberechtigungen für alle übergeordneten Konfigurationsdateien.
Wenn Ihre Anwendung schreibgeschützten Zugriff auf ihre eigene Konfiguration benötigt, wird empfohlen, die GetSection Methodenüberladungen für Webanwendungen zu verwenden. Verwenden Sie für Clientanwendungen die GetSection(String) -Methode.
Diese Methoden bieten Zugriff auf die zwischengespeicherten Konfigurationswerte für die aktuelle Anwendung, die eine bessere Leistung als die Configuration -Klasse aufweist.
Hinweis: Wenn Sie eine statische GetSection Methode verwenden, die einen path-Parameter akzeptiert, muss der path-Parameter auf die Anwendung verweisen, in der der Code ausgeführt wird. Andernfalls wird der Parameter ignoriert und Konfigurationsinformationen für die aktuell ausgeführte Anwendung zurückgegeben.
Sie verwenden eine der Save Methoden, um Konfigurationsinformationen zu schreiben. Beachten Sie, dass der Benutzer oder der Prozess, der schreibt, über die folgenden Berechtigungen verfügen muss:
Schreibberechtigung für die Konfigurationsdatei und das Verzeichnis auf der aktuellen Konfigurationshierarchieebene.
Leseberechtigungen für alle Konfigurationsdateien.
