BitVector32.Equals-Methode

Bestimmt, ob das angegebene Objekt dem BitVector32 entspricht.

Overrides Public Function Equals( _
   ByVal o As Object _) As Boolean
[C#]
public override bool Equals(objecto);
[C++]
public: bool Equals(Object* o);
[JScript]
public override function Equals(
   o : Object) : Boolean;

Parameter

• o
  Das Objekt, das mit dem aktuellen BitVector32 verglichen werden soll.

Rückgabewert

true, wenn das angegebene Objekt dem BitVector32 entspricht, andernfalls false.

Hinweise

Das Objekt o entspricht dem BitVector32, wenn der Typ von o mit dem BitVector32-Typ kompatibel ist und wenn der Wert von o dem Wert von Data entspricht.

Beispiel

[Visual Basic, C#, C++] Im folgenden Codebeispiel wird ein BitVector32 mit einem anderen BitVector32 und einem Int32 verglichen.
