TimeSpan.Negate-Methode

Gibt eine TimeSpan zurück, deren Wert der negierte Wert dieser Instanz ist.

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

Syntax

'Declaration
Public Function Negate As TimeSpan
'Usage
Dim instance As TimeSpan
Dim returnValue As TimeSpan

returnValue = instance.Negate
public TimeSpan Negate ()
public:
TimeSpan Negate ()
public TimeSpan Negate ()
public function Negate () : TimeSpan

Rückgabewert

Derselbe numerische Wert wie diese Instanz, jedoch mit umgekehrtem Vorzeichen.

Ausnahmen

Ausnahmetyp Bedingung

OverflowException

Der negierte Wert dieser Instanz kann nicht durch eine TimeSpan dargestellt werden, d. h., der Wert dieser Instanz ist MinValue.

Beispiel

Im folgenden Codebeispiel wird die Negate-Methode auf verschiedene TimeSpan-Objekte angewendet.
