DateTime.AddMinutes(Double) Metodo

Definizione

Restituisce un nuovo oggetto DateTime che aggiunge il numero specificato di minuti al valore di questa istanza.

public:
 DateTime AddMinutes(double value);
public DateTime AddMinutes (double value);
member this.AddMinutes : double -> DateTime
Public Function AddMinutes (value As Double) As DateTime

Parametri

value
Double

Numero di minuti interi e frazionari. Il parametro value può essere negativo o positivo.

Restituisce

Oggetto il cui valore è la somma della data e dell'ora rappresentate dall'istanza e del numero di minuti rappresentato da value.

Eccezioni

Il risultato DateTime è minore di DateTime.MinValue o maggiore di DateTime.MaxValue.

Esempio

Nell'esempio seguente viene usato il AddMinutes metodo per aggiungere un numero di valori interi e frazionari a una data e un'ora.

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));
}

Commenti

Questo metodo non modifica il valore di questo DateTimeoggetto . Restituisce invece un nuovo DateTime valore il cui valore è il risultato di questa operazione.

La parte frazionaria di è la parte frazionaria di value un minuto. Ad esempio, 4,5 equivale a 4 minuti, 30 secondi, 0 millisecondi e 0 tick.

Nelle versioni precedenti e .NET 6 il value parametro viene arrotondato al millisecondo più vicino. In .NET 7 e versioni successive viene usata la precisione completa Double del value parametro. Tuttavia, a causa dell'accuratezza intrinseca della matematica a virgola mobile, la precisione risultante varia.
