## Remarques

Le paramètre `value` est converti en millisecondes, qui est converti en graduations, et ce nombre de graduations est utilisé pour initialiser la nouvelle TimeSpan.The `value` parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new TimeSpan. Par conséquent, `value` sera considéré comme précis à la milliseconde près.Therefore, `value` will only be considered accurate to the nearest millisecond. Notez que, en raison de la perte de précision du type de données Double, cela peut générer une OverflowException pour les valeurs proches mais toujours dans la plage des MinValue ou des MaxValue, il s’agit de la cause d’un OverflowException, par exemple, lors de la tentative suivante d’instancier un objet TimeSpan.Note that, because of the loss of precision of the Double data type, this can generate an OverflowException for values that are near but still in the range of either MinValue or MaxValue, This is the cause of an OverflowException, for example, in the following attempt to instantiate a TimeSpan object.

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