定義
重要
部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
取得或設定完整日期值的自訂格式字串。
public:
property System::String ^ LongDatePattern { System::String ^ get(); void set(System::String ^ value); };public string LongDatePattern { get; set; }member this.LongDatePattern : string with get, setPublic Property LongDatePattern As String屬性值
完整日期值的自訂格式字串。
例外狀況
此屬性設定為 null。
正在設定屬性，而且 DateTimeFormatInfo 物件為唯讀。
範例
下列範例會顯示幾個文化特性的 LongDatePattern 屬性值。
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:
CULTURE PROPERTY VALUE
en-US dddd, MMMM dd, yyyy
ja-JP yyyy'年'M'月'd'日'
fr-FR dddd d MMMM yyyy
*/
using System;
using System.Globalization;
public class SamplesDTFI {
public static void Main() {
// Displays the values of the pattern properties.
Console.WriteLine( " CULTURE PROPERTY VALUE" );
PrintPattern( "en-US" );
PrintPattern( "ja-JP" );
PrintPattern( "fr-FR" );
}
public static void PrintPattern( String myCulture ) {
DateTimeFormatInfo myDTFI = new CultureInfo( myCulture, false ).DateTimeFormat;
Console.WriteLine( " {0} {1}", myCulture, myDTFI.LongDatePattern );
}
}
/*
This code produces the following output:
CULTURE PROPERTY VALUE
en-US dddd, MMMM d, yyyy
ja-JP yyyy'年'M'月'd'日'
fr-FR dddd d MMMM yyyy
*/
Imports System.Globalization
Public Class SamplesDTFI
Public Shared Sub Main()
' Displays the values of the pattern properties.
Console.WriteLine(" CULTURE PROPERTY VALUE")
PrintPattern("en-US")
PrintPattern("ja-JP")
PrintPattern("fr-FR")
End Sub
Public Shared Sub PrintPattern(myCulture As [String])
Dim myDTFI As DateTimeFormatInfo = New CultureInfo(myCulture, False).DateTimeFormat
Console.WriteLine(" {0} {1}", myCulture, myDTFI.LongDatePattern)
End Sub
End Class
'This code produces the following output:
'
' CULTURE PROPERTY VALUE
' en-US dddd, MMMM d, yyyy
' ja-JP yyyy'年'M'月'd'日'
' fr-FR dddd d MMMM yyyy

備註
屬性 LongDatePattern 會定義由 呼叫 DateTime.ToString 和 DateTimeOffset.ToString 方法所傳回之日期字串的文化特性特定格式，以及提供 「D」 標準格式字串的複合格式字串所傳回。 下列範例說明下列各項之間的關聯性：「D」 標準格式字串、屬性傳 LongDatePattern 回的自訂格式字串，以及日期的文化特性特定標記法。
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
如需可結合的個別自訂格式規範，請參閱自訂 日期和時間格式字串 ，以建構自訂格式字串，例如 「dddd， dd MMMM yyyy」。
您應該將長日期模式中的日期分隔符號設定為確切字串，而不是使用日期分隔符號。 例如，若要取得 MM-DD-yyyy 模式，請將長日期模式設定為 「MM-DD-yyyy」。
如果文化特性所使用的行事曆變更，此屬性的值可能會變更。 例如，下列範例示範當文化特性使用的物件變更時 Calendar ，代表阿拉伯文 (阿拉伯文) 文化特性的 屬性 CultureInfo 如何 LongDatePattern 變更。
using System;
using System.Globalization;
using System.IO;
public class Example
{
public static void Main()
{
DateTime date1 = new DateTime(2011, 8, 7);
CultureInfo ci = CultureInfo.CreateSpecificCulture("ar-SY");
StreamWriter sw = new StreamWriter(@".\arSYCalendars.txt");
sw.WriteLine("{0,-32} {1,-21} {2}\n",
"Calendar", "Long Date Pattern", "Example Date");
foreach (var cal in ci.OptionalCalendars) {
ci.DateTimeFormat.Calendar = cal;
sw.WriteLine("{0,-32} {1,-21} {2}", GetCalendarName(cal),
ci.DateTimeFormat.LongDatePattern,
date1.ToString("D", ci));
}
sw.Close();
}
private static string GetCalendarName(Calendar cal)
{
string calName;
calName = cal.GetType().Name.Substring(0, cal.GetType().Name.IndexOf("Cal"));
if (calName.Equals("Gregorian")) {
GregorianCalendar grCal = cal as GregorianCalendar;
calName += String.Format("-{0}", grCal.CalendarType);
}
return calName;
}
}
// The example generates the following output:
// Calendar Long Date Pattern Example Date
//
// Gregorian-Localized dd MMMM, yyyy 07 آب, 2011
// UmAlQura dd/MMMM/yyyy 07/رمضان/1432
// Hijri dd MMMM, yyyy 08 رمضان, 1432
// Gregorian-USEnglish dddd, MMMM dd, yyyy Sunday, August 07, 2011
// Gregorian-MiddleEastFrench dddd, MMMM dd, yyyy dimanche, août 07, 2011
