Nachfolgend sehen Sie einen Auszug der Konfigurationsdatei, die im obigen Beispiel verwendet wird.

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <configProtectedData>

    <providers>
      <clear />
      <add
         name="TripleDESProtectedConfigurationProvider"
         type="Samples.Aspnet.TripleDESProtectedConfigurationProvider, protectedconfigurationproviderlib, Version=1.0.0.0, Culture=neutral,

    </providers>

  </configProtectedData>

</configuration>

Hinweise

ASP.NET verwendet Anbieter, um bestimmte Dienste auszuführen, die von einem Feature benötigt werden. Beispielsweise verwendet das Mitgliedschaftsfeature einen Anbieter, um die Persistenz von Mitgliedschaftsdaten in einer Datenbank zu koordinieren.

In einer Konfigurationsdatei werden einzelne Anbieter einem providers Element innerhalb eines bestimmten Featureabschnitts hinzugefügt.

Die ProviderSettings Klasse stellt eine bestimmte Gruppe von Einstellungen dar, die dem providers Element in einem Konfigurationsabschnitt hinzugefügt werden. In der Regel enthalten die durch die add Direktive angegebenen Konfigurationsattribute einen Namen, einen Typ und andere Eigenschaften.
