public int Year { get; }
member this.Year : int
Public ReadOnly Property Year As Integer

プロパティ値

1 から 9999 までの間の年。The year, between 1 and 9999.

プロパティのYear例を次に示します。The following example demonstrates the Year property.

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

注釈

プロパティYearは、グレゴリオ暦の現在のインスタンスの年を返します。The Year property returns the year of the current instance in the Gregorian calendar. 現在のカルチャの既定の暦を使用して年を返すことはありません。It does not return the year using the default calendar of the current culture. 特定の暦を使用して年を取得するには、次GetYearのコードに示すように、その暦のメソッドを呼び出すことができます。To retrieve the year using a particular calendar, you can call that calendar's GetYear method, as the following code shows.

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 
   }
}

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
