DateTimeFormatInfo.LongDatePattern Properti

Definisi

Mendapatkan atau mengatur string format kustom untuk nilai tanggal panjang.

public:
 property System::String ^ LongDatePattern { System::String ^ get(); void set(System::String ^ value); };
public string LongDatePattern { get; set; }
member this.LongDatePattern : string with get, set
Public Property LongDatePattern As String

Nilai Properti

String format kustom untuk nilai tanggal panjang.

Pengecualian

Properti sedang diatur ke null.

Properti sedang diatur dan DateTimeFormatInfo objek bersifat baca-saja.

Contoh

Contoh berikut menampilkan nilai LongDatePattern properti untuk beberapa budaya.

using namespace System;
using namespace System::Globalization;
void PrintPattern( String^ myCulture )
{
   CultureInfo^ MyCI = gcnew CultureInfo( myCulture,false );
   DateTimeFormatInfo^ myDTFI = MyCI->DateTimeFormat;
   Console::WriteLine( " {0} {1}", myCulture, myDTFI->LongDatePattern );
}

int main()
{
   
   // Displays the values of the pattern properties.
   Console::WriteLine( " CULTURE    PROPERTY VALUE" );
   PrintPattern( "en-US" );
   PrintPattern( "ja-JP" );
   PrintPattern( "fr-FR" );
}

/*
This code produces the following output:

Keterangan

Properti LongDatePattern mendefinisikan format khusus budaya dari string tanggal yang dikembalikan oleh panggilan ke DateTime.ToString metode dan DateTimeOffset.ToString dan dengan string format komposit yang disediakan string format standar "D". Contoh berikut mengilustrasikan hubungan di antara yang berikut: string format standar "D", string format kustom yang dikembalikan oleh LongDatePattern properti , dan representasi khusus budaya dari tanggal.

using System;
using System.Globalization;

public class Example
{
   public static void Main()
   {
      DateTime date1 = new DateTime(2011, 11, 12);
      string[] cultureNames = { "en-US", "fr-FR", "ru-RU", "de-DE" };
      Console.WriteLine("{0,-7} {1,-20} {2:D}\n", "Culture", "Long Date Pattern", "Date");
      foreach (var cultureName in cultureNames) {
         CultureInfo culture = CultureInfo.CreateSpecificCulture(cultureName);
         Console.WriteLine("{0,-7} {1,-20} {2}",
                           culture.Name,
                           culture.DateTimeFormat.LongDatePattern,
                           date1.ToString("D", culture));
      }
   }
}
// The example displays the following output:
//    Culture Long Date Pattern    Date
//
//    en-US   dddd, MMMM d, yyyy   Saturday, November 12, 2011
//    fr-FR   dddd d MMMM yyyy     samedi 12 novembre 2011
//    ru-RU   d MMMM yyyy 'г.'     12 ноября 2011 г.
//    de-DE   dddd, d. MMMM yyyy   Samstag, 12. November 2011
Imports System.Globalization

Module Example
   Public Sub Main()
      Dim date1 As Date = #11/12/2011#
      Dim cultureNames() As String = { "en-US", "fr-FR", "ru-RU", "de-DE" }
      Console.WriteLine("{0,-7} {1,-20} {2:D}", "Culture", "Long Date Pattern", "Date")
      Console.WriteLine()
      For Each cultureName In cultureNames
         Dim culture As CultureInfo = CultureInfo.CreateSpecificCulture(cultureName)
         Console.WriteLine("{0,-7} {1,-20} {2}", culture.Name, culture.DateTimeFormat.LongDatePattern, 
                           date1.ToString("D", culture))                 
      Next
   End Sub
End Module
' The example displays the following output:
'    Culture Long Date Pattern    Date
'
'    en-US   dddd, MMMM d, yyyy   Saturday, November 12, 2011
'    fr-FR   dddd d MMMM yyyy     samedi 12 novembre 2011
'    ru-RU   d MMMM yyyy 'г.'     12 ноября 2011 г.
'    de-DE   dddd, d. MMMM yyyy   Samstag, 12. November 2011

Lihat String Format Tanggal dan Waktu Kustom untuk penentu format kustom individual yang dapat digabungkan untuk membuat string format kustom seperti "dddd, dd MMMM yyyy".

Anda harus mengatur pemisah tanggal dalam pola tanggal panjang ke string yang tepat alih-alih menggunakan tempat penampung pemisah tanggal. Misalnya, untuk mendapatkan pola MM-DD-yyyy, atur pola tanggal panjang ke "MM-DD-yyyy".

Nilai properti ini dapat berubah jika kalender yang digunakan oleh budaya berubah. Misalnya, contoh berikut menunjukkan bagaimana LongDatePattern properti CultureInfo objek yang mewakili budaya Arab (Suriah) berubah ketika objek yang Calendar digunakan oleh budaya berubah.
