Esempio

Nell'esempio seguente viene illustrata la Year proprietà .

System::DateTime moment = System::DateTime(
   1999, 1, 13, 3, 57, 32, 11 );

// Year gets 1999.
int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

// Day gets 13.
int day = moment.Day;

// Hour gets 3.
int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;

System.DateTime moment = new System.DateTime(
                                1999, 1, 13, 3, 57, 32, 11);
// Year gets 1999.
int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

// Day gets 13.
int day = moment.Day;

// Hour gets 3.
int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;

Dim moment As New System.DateTime(1999, 1, 13, 3, 57, 32, 11)

' Year gets 1999.
Dim year As Integer = moment.Year

' Month gets 1 (January).
Dim month As Integer = moment.Month

' Day gets 13.
Dim day As Integer = moment.Day

' Hour gets 3.
Dim hour As Integer = moment.Hour

' Minute gets 57.
Dim minute As Integer = moment.Minute

' Second gets 32.
Dim second As Integer = moment.Second

' Millisecond gets 11.
Dim millisecond As Integer = moment.Millisecond

Commenti

La Year proprietà restituisce l'anno dell'istanza corrente nel calendario gregoriano. Non restituisce l'anno usando il calendario predefinito delle impostazioni cultura correnti. Per recuperare l'anno usando un calendario specifico, è possibile chiamare il metodo del GetYear calendario, come illustrato nel codice seguente.

using System;
using System.Globalization;
using System.Threading;

public class YearMethodExample
{
    public static void Main()
    {
      // Initialize date variable and display year
      DateTime date1 = new DateTime(2008, 1, 1, 6, 32, 0);
      Console.WriteLine(date1.Year);                    // Displays 2008

      // Set culture to th-TH
      Thread.CurrentThread.CurrentCulture = new CultureInfo("th-TH");
      Console.WriteLine(date1.Year);                    // Displays 2008

      // display year using current culture's calendar
      Calendar thaiCalendar = CultureInfo.CurrentCulture.Calendar;
      Console.WriteLine(thaiCalendar.GetYear(date1));   // Displays 2551

      // display year using Persian calendar
      PersianCalendar persianCalendar = new PersianCalendar();
      Console.WriteLine(persianCalendar.GetYear(date1)); // Displays 1386
   }
}

Imports System.Globalization
Imports System.Threading

Module YearMethodExample
   Public Sub Main()
      ' Initialize date variable and display year
      Dim date1 As Date = #01/01/2008 6:32AM#
      Console.WriteLine(date1.Year)       ' Displays 2008
      
      ' Set culture to th-TH
      Thread.CurrentThread.CurrentCulture = New CultureInfo("th-TH")
      Console.WriteLine(date1.Year)        ' Displays 2008
      
      ' display year using current culture's calendar 
      Dim thaiCalendar As Calendar = CultureInfo.CurrentCulture.Calendar
      Console.WriteLine(thaiCalendar.GetYear(date1))    ' Displays 2551
      
      ' display year using Persian calendar
      Dim persianCalendar As New PersianCalendar()
      Console.WriteLine(persianCalendar.GetYear(date1))  ' Displays 1386 
   End Sub
End Module
