## Remarques

Le `value` paramètre est converti en millisecondes, qui est converti en graduations, et ce nombre de graduations est utilisé pour initialiser le nouveau 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` , est 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 Double type de données, cela peut générer OverflowException un pour les valeurs proches, mais toujours MinValue dans la plage de ou MaxValue, il s’agit de la cause OverflowExceptiond’un, par exemple, dans la après la tentative d’instanciation d’un TimeSpan objet.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)
