Właściwości

ErrorCode	Pobiera kod błędu dla obiektu lub pliku.
ErrorString	Pobiera opis elementu ErrorCode.
MajorRef	Pobiera wartość klucza dla obiektu, który spowodował błąd, jeśli ma to zastosowanie.
MinorRef	Pobiera dokładną specyfikację elementu, który spowodował błąd, na przykład nazwę właściwości.
Name	Pobiera nazwę obiektu lub pliku, który spowodował błąd.

Metody

Equals(Object)	Określa, czy dany obiekt jest taki sam, jak bieżący obiekt. (Odziedziczone po Object)
GetHashCode()	Służy jako domyślna funkcja skrótu. (Odziedziczone po Object)
GetType()	Type Pobiera bieżące wystąpienie. (Odziedziczone po Object)
MemberwiseClone()	Tworzy płytkią kopię bieżącego Objectelementu . (Odziedziczone po Object)
ToString()	Zwraca ciąg reprezentujący bieżący obiekt. (Odziedziczone po Object)
