DateTimeFormatInfo.ShortDatePattern 屬性

定義

取得或設定簡短日期值的自訂格式字串。

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

屬性值

String

簡短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

下列範例會顯示內容值 ShortDatePattern ,以及使用 ShortDatePattern 幾個文化特性之 屬性格式化的日期值。

using System;
using System.Globalization;

public class SamplesDTFI
{
   public static void Main()
   {
      string[]  cultures = { "en-US", "ja-JP", "fr-FR" };
      DateTime date1 = new DateTime(2011, 5, 1);

      Console.WriteLine(" {0,7} {1,19} {2,10}\n", "CULTURE", "PROPERTY VALUE", "DATE");

      foreach (var culture in cultures) {
         DateTimeFormatInfo dtfi = CultureInfo.CreateSpecificCulture(culture).DateTimeFormat;
         Console.WriteLine(" {0,7} {1,19} {2,10}", culture,
                           dtfi.ShortDatePattern,
                           date1.ToString("d", dtfi));
      }
   }
}
// The example displays the following output:
//        CULTURE      PROPERTY VALUE       DATE
//
//          en-US            M/d/yyyy   5/1/2011
//          ja-JP          yyyy/MM/dd 2011/05/01
//          fr-FR          dd/MM/yyyy 01/05/2011
Imports System.Globalization

Public Class SamplesDTFI
   Public Shared Sub Main()
      Dim cultures() As String = { "en-US", "ja-JP", "fr-FR" }
      Dim date1 As Date = #05/01/2011#
      
      Console.WriteLine(" {0,7} {1,19} {2,10}", "CULTURE", "PROPERTY VALUE", "DATE")
      Console.WriteLine()
      
      For Each culture As String In cultures
         Dim dtfi As DateTimeFormatInfo = CultureInfo.CreateSpecificCulture(culture).DateTimeFormat
         Console.WriteLine(" {0,7} {1,19} {2,10}", culture, 
                           dtfi.ShortDatePattern, 
                           date1.ToString("d", dtfi))
      Next                     
   End Sub 
End Class
' The example displays the following output:
'        CULTURE      PROPERTY VALUE       DATE
'       
'          en-US            M/d/yyyy   5/1/2011
'          ja-JP          yyyy/MM/dd 2011/05/01
'          fr-FR          dd/MM/yyyy 01/05/2011

下列範例會 ShortDatePattern 修改 物件的 屬性,此物件 DateTimeFormatInfo 代表英文 (美國) 文化特性的格式設定慣例。 它也會顯示日期值兩次,先反映原始 ShortDatePattern 屬性,然後反映新的屬性值。

using System;
using System.Globalization;

public class Example
{
   public static void Main()
   {
      DateTimeFormatInfo dtfi = CultureInfo.CreateSpecificCulture("en-US").DateTimeFormat;
      DateTime date1 = new DateTime(2011, 5, 1);
      Console.WriteLine("Original Short Date Pattern:");
      Console.WriteLine("   {0}: {1}", dtfi.ShortDatePattern,
                                       date1.ToString("d", dtfi));
      dtfi.DateSeparator = "-";
      dtfi.ShortDatePattern = @"yyyy/MM/dd";
      Console.WriteLine("Revised Short Date Pattern:");
      Console.WriteLine("   {0}: {1}", dtfi.ShortDatePattern,
                                       date1.ToString("d", dtfi));
   }
}
// The example displays the following output:
//       Original Short Date Pattern:
//          M/d/yyyy: 5/1/2011
//       Revised Short Date Pattern:
//          yyyy/MM/dd: 2011-05-01
Imports System.Globalization

Module Example
   Public Sub Main()
      Dim dtfi As DateTimeFormatInfo = CultureInfo.CreateSpecificCulture("en-US").DateTimeFormat
      Dim date1 As DateTime = #05/01/2011#
      Console.WriteLine("Original Short Date Pattern:")
      Console.WriteLine("   {0}: {1}", dtfi.ShortDatePattern, 
                                       date1.ToString("d", dtfi))
      dtfi.DateSeparator = "-"
      dtfi.ShortDatePattern = "yyyy/MM/dd"
      Console.WriteLine("Revised Short Date Pattern:")
      Console.WriteLine("   {0}: {1}", dtfi.ShortDatePattern, 
                                       date1.ToString("d", dtfi))
   End Sub
End Module
' The example displays the following output:
'    Original Short Date Pattern:
'       M/d/yyyy: 5/1/2011
'    Revised Short Date Pattern:
'       YYYY/MM/dd: 2011-05-01

備註

屬性 ShortDatePattern 會定義由 呼叫 DateTime.ToStringDateTimeOffset.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。

如果屬性的值變更, Calendar 此屬性就會受到影響。
