Hinweise

Der parameter value wird in Millisekunden konvertiert, der in Teilstriche konvertiert wird und diese Anzahl von Teilstrichen verwendet wird, um die neue TimeSpanzu initialisieren. Daher gilt value nur als genau für die nächste Millisekunden. Beachten Sie, dass aufgrund des Verlusts der Genauigkeit des Double Datentyps eine OverflowException für Werte generiert werden kann, die sich in der Nähe befinden, aber sich weiterhin im Bereich von MinValue oder MaxValuebefinden. Dies ist die Ursache eines OverflowException, z. B. im folgenden Versuch, ein TimeSpan -Objekt instanziieren.

// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromSeconds(TimeSpan.MaxValue.TotalSeconds);

// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromSeconds TimeSpan.MaxValue.TotalSeconds

' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromSeconds(TimeSpan.MaxValue.TotalSeconds)
