Bestimmt, ob es sich bei dem angegebenen Objekt um dieselbe Instanz handelt wie der aktuelle SortKey.
Overrides Public Function Equals( _
ByVal value As Object _) As Boolean
[C#]
public override bool Equals(objectvalue);
[C++]
public: bool Equals(Object* value);
[JScript]
public override function Equals(
value : Object) : Boolean;
Parameter
- value
Das Objekt, das mit dem aktuellen SortKey verglichen werden soll.
Rückgabewert
true, wenn es sich bei dem angegebenen Objekt um dieselbe Instanz handelt wie der aktuelle SortKey, andernfalls false.
Hinweise
Diese Methode überschreibt Object.Equals.
Zwei SortKey-Instanzen gelten als gleich, wenn beide Instanzen unter Verwendung derselben Zeichenfolge und denselben CompareOptions aus CompareInfo-Instanzen erstellt wurden, die als gleich angesehen werden.
Beispiel
[Visual Basic, C#, C++] Im folgenden Codebeispiel werden die Ergebnisse von Equals beim Vergleich mit anderen SortKey-Objekten dargestellt.
