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

属性值

Int32

年份(介于 1 和 9999 之间)。

示例

以下示例演示了该 Year 属性。

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;
open System


let moment = System.DateTime(1999, 1, 13, 3, 57, 32, 11)

// Year gets 1999.
let year = moment.Year

// Month gets 1 (January).
let month = moment.Month

// Day gets 13.
let day = moment.Day

// Hour gets 3.
let hour = moment.Hour

// Minute gets 57.
let minute = moment.Minute

// Second gets 32.
let second = moment.Second

// Millisecond gets 11.
let 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

注解

Year 属性返回公历中当前实例的年份。 它不使用当前区域性的默认日历返回年份。 若要使用特定日历检索年份,可以调用该日历 GetYear 的方法,如以下代码所示。

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
   }
}
open System
open System.Globalization
open System.Threading

// Initialize date variable and display year
let date1 = DateTime(2008, 1, 1, 6, 32, 0)
printfn $"{date1.Year}"                    // Displays 2008

// Set culture to th-TH
Thread.CurrentThread.CurrentCulture <- CultureInfo "th-TH"
printfn $"{date1.Year}"                    // Displays 2008

// display year using current culture's calendar
let thaiCalendar = CultureInfo.CurrentCulture.Calendar
printfn $"{thaiCalendar.GetYear date1}"   // Displays 2551

// display year using Persian calendar
let persianCalendar = PersianCalendar()
printfn $"{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
