Remarques

La seconds valeur est ajoutée au .DateTime S’il seconds est négatif, le résultat DateTime est antérieur à celui spécifié DateTime.

La partie jour du résultat DateTime est affectée si l’heure résultante est en dehors du jour de la valeur spécifiée DateTime. La partie mois du résultat est affectée si le jour résultant DateTime est en dehors du mois spécifié DateTime. La partie année du résultat est affectée si le mois résultant DateTime est en dehors de l’année DateTimespécifiée. La partie ère du résultat est affectée si l’année résultante DateTime est en dehors de l’ère de l’élément spécifié DateTime.

La Kind propriété de la valeur retournée DateTime est toujours égale DateTimeKind.Unspecified. Vous pouvez conserver la Kind propriété du time paramètre en appelant la DateTime.SpecifyKind méthode, comme l’illustre l’exemple suivant.

returnTime = DateTime.SpecifyKind(cal.AddSeconds(time, seconds), time.Kind);

returnTime = DateTime.SpecifyKind(cal.AddSeconds(time, seconds), time.Kind)
