DateTimeFormatInfo.ShortDatePattern 屬性
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, setPublic Property ShortDatePattern As String屬性值
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的值 ShortDatePattern ，以及 ShortDatePattern 針對一些文化特性使用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 ShortDatePattern 會修改物件的屬性 DateTimeFormatInfo ，該物件表示英文 (美國) 文化特性的格式化慣例。 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
ShortDatePattern屬性會定義特定文化特性格式的日期字串，這些格式是由呼叫 DateTime.ToString 和 DateTimeOffset.ToString 方法以及提供 "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，這個屬性會受到影響 Calendar 。
