Exemples

L’exemple suivant utilise la AddMinutes méthode pour ajouter un nombre de valeurs entières et fractionnaires à une date et une heure.

using namespace System;

void main()
{
   DateTime dateValue(2013, 9, 15, 12, 0, 0);
   
   array<Double>^ minutes = { .01667, .08333, .16667, .25, .33333, 
                              .5, .66667, 1, 2, 15, 30, 17, 45, 
                              60, 180, 60 * 24 };
   
   for each (Double minute in minutes)
      Console::WriteLine("{0} + {1} minute(s) = {2}", dateValue, minute, 
                         dateValue.AddMinutes(minute));

Remarques

Cette méthode ne modifie pas la valeur de ce DateTime. Au lieu de cela, il retourne un nouveau DateTime dont la valeur est le résultat de cette opération.

La partie fractionnaire de value est la partie fractionnaire d’une minute. Par exemple, 4,5 équivaut à 4 minutes, 30 secondes, 0 milliseconde et 0 ticks.

Dans .NET 6 et les versions antérieures, le value paramètre est arrondi à la milliseconde la plus proche. Dans .NET 7 et versions ultérieures, la précision complète Double du value paramètre est utilisée. Toutefois, en raison de l’imprécision inhérente des mathématiques à virgule flottante, la précision obtenue varie.
