Exempel

I följande exempel visas egenskapen Day .

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

Kommentarer

Egenskapen Day returnerar alltid dagen i månaden i den gregorianska kalendern, även om det aktuella DateTime värdet instansierades med någon annan kalender eller om den aktuella kulturens standardkalender inte är den gregorianska kalendern. Om du vill hämta dagen i månaden för ett visst datum med hjälp av en annan kalender anropar du den kalenderns Calendar.GetDayOfMonth metod. I följande exempel används både Day egenskapen och HijriCalendar.GetDayOfMonth metoden för att hämta dagen i månaden för ett DateTime värde som instansieras med hjälp av Hijri-kalendern.

// Return day of 1/13/2009.
DateTime dateGregorian = new DateTime(2009, 1, 13);
Console.WriteLine(dateGregorian.Day);
// Displays 13 (Gregorian day).

// Create date of 1/13/2009 using Hijri calendar.
HijriCalendar hijri = new HijriCalendar();
DateTime dateHijri = new DateTime(1430, 1, 17, hijri);
// Return day of date created using Hijri calendar.
Console.WriteLine(dateHijri.Day);
// Displays 13 (Gregorian day).

// Display day of date in Hijri calendar.
Console.WriteLine(hijri.GetDayOfMonth(dateHijri));
// Displays 17 (Hijri day).

// Return day of 1/13/2009.
let dateGregorian = DateTime(2009, 1, 13)
printfn $"{dateGregorian.Day}"
// Displays 13 (Gregorian day).

// Create date of 1/13/2009 using Hijri calendar.
let hijri = HijriCalendar()
let dateHijri = DateTime(1430, 1, 17, hijri)
// Return day of date created using Hijri calendar.
printfn $"{dateHijri.Day}"
// Displays 13 (Gregorian day).

// Display day of date in Hijri calendar.
printfn $"{hijri.GetDayOfMonth dateHijri}"
// Displays 17 (Hijri day).

' Return day of 1/13/2009.
Dim dateGregorian As Date = #1/13/2009#
Console.WriteLine(dateGregorian.Day)
' Displays 13 (Gregorian date).

' Create date of 1/13/2009 using Hijri calendar.
Dim hijri As New HijriCalendar()
Dim dateHijri As Date = New Date(1430, 1, 17, hijri)
' Return day of date created using Hijri calendar.
Console.WriteLine(dateHijri.Day)                   
' Displays 13 (Gregorian date).

' Display day of date in Hijri calendar.
Console.WriteLine(hijri.GetDayOfMonth(dateHijri))  
' Displays 17 (Hijri date).

På samma sätt använder följande exempel både Day egenskapen och HijriCalendar.GetDayOfMonth metoden för att hämta den dag i månaden då den aktuella kulturen är ar-SA, som använder Hijri som standardkalender.

CultureInfo originalCulture = Thread.CurrentThread.CurrentCulture;

// Change current culture to ar-SA.
CultureInfo ci = new CultureInfo("ar-SA");
Thread.CurrentThread.CurrentCulture = ci;

DateTime hijriDate = new DateTime(1430, 1, 17,
                         Thread.CurrentThread.CurrentCulture.Calendar);
// Display date (uses calendar of current culture by default).
Console.WriteLine(hijriDate.ToString("dd-MM-yyyy"));
// Displays 17-01-1430.

// Display day of 17th of Muharram
Console.WriteLine(hijriDate.Day);
// Displays 13 (corresponding day of January in Gregorian calendar).

// Display day of 17th of Muharram in Hijri calendar.
Console.WriteLine(Thread.CurrentThread.CurrentCulture.Calendar.GetDayOfMonth(hijriDate));
// Displays 17.

Thread.CurrentThread.CurrentCulture = originalCulture;

open System
open System.Globalization
open System.Threading

let originalCulture = Thread.CurrentThread.CurrentCulture

// Change current culture to ar-SA.
let ci = CultureInfo "ar-SA"
Thread.CurrentThread.CurrentCulture <- ci

let hijriDate = new DateTime(1430, 1, 17,
                        Thread.CurrentThread.CurrentCulture.Calendar);
// Display date (uses calendar of current culture by default).
printfn $"""{hijriDate.ToString "dd-MM-yyyy"}"""
// Displays 17-01-1430.

// Display day of 17th of Muharram
printfn $"{hijriDate.Day}"
// Displays 13 (corresponding day of January in Gregorian calendar).

// Display day of 17th of Muharram in Hijri calendar.
printfn $"{Thread.CurrentThread.CurrentCulture.Calendar.GetDayOfMonth hijriDate}"
// Displays 17.

Thread.CurrentThread.CurrentCulture <- originalCulture

Dim originalCulture As CultureInfo = Thread.CurrentThread.CurrentCulture

' Change current culture to ar-SA.
Dim ci As New CultureInfo("ar-SA")
Thread.CurrentThread.CurrentCulture = ci

Dim hijriDate As New Date(1430, 1, 17, _
                          Thread.CurrentThread.CurrentCulture.Calendar)
' Display date (uses calendar of current culture by default).
Console.WriteLine(hijriDate.ToString("dd-MM-yyyy"))
' Displays 17-01-1430.

' Display day of 17th of Muharram
Console.WriteLine(hijriDate.Day)
' Displays 13 (corresponding day of January in Gregorian calendar).

' Display day of 17th of Muharram in Hijri calendar.
Console.WriteLine(Thread.CurrentThread.CurrentCulture.Calendar.GetDayOfMonth(hijriDate))
' Displays 17.

Thread.CurrentThread.CurrentCulture = originalCulture
