public string FullDateTimePattern { get; set; }
member this.FullDateTimePattern : string with get, set
Public Property FullDateTimePattern As String

屬性值

完整日期和時間值的自訂格式字串。The custom format string for a long date and long time value.

正在將屬性設定為 nullThe property is being set to null.

正在設定屬性,而且 DateTimeFormatInfo 物件為唯讀。The property is being set and the DateTimeFormatInfo object is read-only.

範例

下列範例會顯示一些文化特性FullDateTimePattern的值。The following example displays the value of FullDateTimePattern for a few cultures.

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->FullDateTimePattern );
}

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

/*

CULTURE    PROPERTY VALUE
en-US     dddd, MMMM dd, yyyy h:mm:ss tt
ja-JP     yyyy'?'M'?'d'?' H:mm:ss
fr-FR     dddd d MMMM yyyy HH:mm:ss

*/
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.FullDateTimePattern );

   }

}

/*

  ja-JP     yyyy'?'M'?'d'?' H:mm:ss

*/
Imports System.Globalization

   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.FullDateTimePattern)

   End Sub

'This code produces the following output.  The question marks take the place of native script characters.

' CULTURE    PROPERTY VALUE
'  en-US     dddd, MMMM dd, yyyy h:mm:ss tt

備註

"F" 標準格式字串是FullDateTimePattern屬性的別名。The "F" standard format string is an alias for the FullDateTimePattern property. 換句話說,指派給這個屬性的自訂格式字串會定義 "F" 標準格式字串的結果字串格式。In other words, the custom format string assigned to this property defines the format of the result string for the "F" standard format string. 如需詳細資訊,請參閱標準日期和時間格式字串For more information, see Standard Date and Time Format Strings.

FullDateTimePattern屬性的值會藉由串連以空格分隔的LongDatePatternLongTimePattern屬性,以動態方式產生。The value of the FullDateTimePattern property is generated dynamically by concatenating the LongDatePattern and LongTimePattern properties separated by a space. 此動態指派會在下列情況下發生:This dynamic assignment occurs under the following conditions:

  • 如果在明確設定屬性值之前先行抓取。If the property value is retrieved before it has been explicitly set.

  • LongDatePattern屬性的值變更時。When the value of the LongDatePattern property changes.

  • LongTimePattern屬性的值變更時。When the value of the LongTimePattern property changes.

如果Calendar屬性的值變更,這個屬性會受到影響。This property is affected if the value of the Calendar property changes.
