TimeSpan.FromSeconds-Methode
Gibt eine TimeSpan zurück, die eine angegebene Anzahl von Sekunden darstellt. Die Angabe wird auf die nächste Millisekunde gerundet.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Shared Function FromSeconds ( _
value As Double _
) As TimeSpan
'Usage
Dim value As Double
Dim returnValue As TimeSpan
returnValue = TimeSpan.FromSeconds(value)
public static TimeSpan FromSeconds (
double value
)
public:
static TimeSpan FromSeconds (
double value
)
public static TimeSpan FromSeconds (
double value
)
public static function FromSeconds (
value : double
) : TimeSpan
Parameter
- value
Eine Anzahl von Sekunden, auf die nächste Millisekunde gerundet.
Rückgabewert
Eine TimeSpan, die value darstellt.
Ausnahmen
| Ausnahmetyp | Bedingung |
|---|---|
value ist gleich Double.NaN. |
Hinweise
Der value-Parameter wird in Millisekunden konvertiert, diese werden in Ticks konvertiert, und die neue TimeSpan wird mit dieser Anzahl von Ticks initialisiert. Daher wird value nur als bis auf die nächste Millisekunde genau betrachtet.
Wenn value Double.PositiveInfinity ist, wird MaxValue zurückgegeben. Wenn value Double.NegativeInfinity ist, wird MinValue zurückgegeben.
Beispiel
Im folgenden Codebeispiel werden verschiedene TimeSpan-Objekte mithilfe der FromSeconds-Methode erstellt.
