Alcune informazioni sono relative alla release non definitiva del prodotto, che potrebbe subire modifiche significative prima della release definitiva. Microsoft non riconosce alcuna garanzia, espressa o implicita, in merito alle informazioni qui fornite.
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.
