Beispiele

Im folgenden Beispiel wird das UnknownNode -Ereignis von XmlSerializer verwendet, um verschiedene Eigenschaften eines unbekannten XML-Knotens zu drucken, die beim Aufrufen der -Methode der XmlSerializer -Klasse Deserialize gefunden werden.

Hinweise

Weitere Informationen zum Behandeln von Ereignissen finden Sie unter behandeln und Auslösen von Ereignissen.

Das UnknownNode Ereignis kann nur auftreten, wenn Sie die Deserialize -Methode aufrufen.

Eigenschaften

LineNumber	Ruft die Zeilennummer des unbekannten XML-Knotens ab.
LinePosition	Ruft die Position des unbekannten XML-Knotens in der Zeile ab.
LocalName	Ruft den lokalen XML-Namen des gerade deserialisierten XML-Knotens ab.
Name	Ruft den Namen des gerade deserialisierten XML-Knotens ab.
NamespaceURI	Ruft den Namespace-URI ab, der dem gerade deserialisierten XML-Knoten zugeordnet ist.
NodeType	Ruft den Typ des gerade deserialisierten XML-Knotens ab.
ObjectBeingDeserialized	Ruft das Objekt ab, das gerade deserialisiert wird.
Text	Ruft den Text des gerade deserialisierten XML-Knotens ab.

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)
