Hinweise

Die Sinkanbieterdaten sind eine Struktur der Konfigurationsinformationen, die in den Konfigurationsknoten " <provider> Element" (Vorlage) gespeichert sind. Alle Sinkanbieter müssen einen Konstruktor haben, der eine Eigenschaft und ICollection eine IDictionary dieser Strukturen akzeptiert, wenn sie aus einer Konfigurationsdatei verwendet werden möchten.

Konstruktoren

SinkProviderData(String)

Initialisiert eine neue Instanz der SinkProviderData-Klasse.

Eigenschaften

Children	Ruft eine Liste der untergeordneten SinkProviderData-Knoten ab.
Name	Ruft den Namen des Senkenanbieters ab, dem die Daten im aktuellen SinkProviderData-Objekt zugeordnet sind.
Properties	Ruft ein Wörterbuch ab, über das auf Eigenschaften für den Senkenanbieter zugegriffen werden kann.

Methoden

Equals(Object)	Bestimmt, ob das angegebene Objekt gleich dem aktuellen Objekt ist. (Geerbt von Object)
GetHashCode()	Fungiert als Standardhashfunktion. (Geerbt von Object)
GetType()	Ruft den Type der aktuellen Instanz ab. (Geerbt von Object)
MemberwiseClone()	Erstellt eine flache Kopie des aktuellen Object. (Geerbt von Object)
ToString()	Gibt eine Zeichenfolge zurück, die das aktuelle Objekt darstellt. (Geerbt von Object)
