   pIndex = timeInterval->IndexOf( '.', pIndex );
   if ( pIndex < 0 )
      timeInterval = String::Concat( timeInterval, "        " );

Remarques

Le paramètre value est converti en graduations, et ce nombre de graduations est utilisé pour initialiser la nouvelle TimeSpan. Par conséquent, value sera considéré comme exact à la milliseconde la plus proche. Notez que, en raison de la perte de précision du type de données Double, cette conversion peut générer une OverflowException pour les valeurs proches mais toujours dans la plage de MinValue ou de MaxValue. Par exemple, cela provoque une OverflowException dans la tentative suivante d’instancier un objet TimeSpan.

// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds);
// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromMilliseconds TimeSpan.MaxValue.TotalMilliseconds
' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromMilliseconds(TimeSpan.MaxValue.TotalMilliseconds)
