Remarques
Le value
paramètre est converti en millisecondes, qui est converti en ticks, et ce nombre de graduations est utilisé pour initialiser le nouveau TimeSpan. Par conséquent, value
ne sera considéré comme précis qu’à la milliseconde la plus proche. Notez que, en raison de la perte de précision du type de Double données, cette conversion peut générer un OverflowException pour les valeurs qui sont proches de , mais toujours dans la plage de MinValue ou MaxValue. Par exemple, cela provoque un OverflowException dans la tentative suivante d’instancier un TimeSpan objet.
// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromMinutes(TimeSpan.MaxValue.TotalMinutes);
// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromMinutes TimeSpan.MaxValue.TotalMinutes
' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromMinutes(TimeSpan.MaxValue.TotalMinutes)
