OperatingSystem.Clone-Methode

Erstellt ein OperatingSystem-Objekt, das mit dieser Instanz identisch ist.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

Syntax

'Declaration
Public Function Clone As Object
'Usage
Dim instance As OperatingSystem
Dim returnValue As Object

returnValue = instance.Clone

public Object Clone ()

public:
virtual Object^ Clone () sealed

public final Object Clone ()

public final function Clone () : Object

Rückgabewert

Ein OperatingSystem-Objekt, das eine Kopie dieser Instanz darstellt.

Beispiel

Im folgenden Codebeispiel wird die Verwendung der Clone-Methode zum Erstellen einer Kopie eines OperatingSystem-Objekts veranschaulicht. Das geklonte Objekt wird mit dem Originalobjekt verglichen, um zu zeigen, dass es sich nicht um dasselbe Objekt handelt.
