Beispiele

Im folgenden Beispiel wird die Day -Eigenschaft veranschaulicht.

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.

// Millisecond gets 11.
let millisecond = moment.Millisecond

Hinweise

Die Day -Eigenschaft gibt immer den Tag des Monats im gregorianischen Kalender zurück, auch wenn der aktuelle DateTime Wert mithilfe eines anderen Kalenders instanziiert wurde oder wenn der Standardkalender der aktuellen Kultur nicht der gregorianische Kalender ist. Um den Tag des Monats eines bestimmten Datums mithilfe eines anderen Kalenders abzurufen, rufen Sie die Methode dieses Kalenders Calendar.GetDayOfMonth auf. Im folgenden Beispiel werden sowohl die Day -Eigenschaft als auch die HijriCalendar.GetDayOfMonth -Methode verwendet, um den Tag des Monats für einen DateTime Wert abzurufen, der mithilfe des Hijri-Kalenders instanziiert wird.

// 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).

Analog dazu werden im folgenden Beispiel sowohl die Day -Eigenschaft als auch die HijriCalendar.GetDayOfMonth -Methode verwendet, um den Tag des Monats abzurufen, an dem die aktuelle Kultur ar-SA ist, wobei Hijri als Standardkalender verwendet wird.

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
