DateTime.Date 属性

定义

获取此实例的日期部分。Gets the date component of this instance.

public:
 property DateTime Date { DateTime get(); };
public DateTime Date { get; }
member this.Date : DateTime
Public ReadOnly Property Date As DateTime

属性值

一个新对象,其日期与此实例相同,时间值设置为午夜 12:00:00 (00:00:00)。A new object with the same date as this instance, and the time value set to 12:00:00 midnight (00:00:00).

示例

下面的示例使用 Date 属性提取 DateTime 值的日期部分,其时间部分设置为零(或0:00:00 或午夜)。The following example uses the Date property to extract the date component of a DateTime value with its time component set to zero (or 0:00:00, or midnight). 它还说明了根据显示 DateTime 值时使用的格式字符串,时间部分可以继续出现在格式化的输出中。It also illustrates that, depending on the format string used when displaying the DateTime value, the time component can continue to appear in formatted output.

using namespace System;

void main()
{
   DateTime^ date1 = gcnew DateTime(2008, 6, 1, 7, 47, 0);
   Console::WriteLine(date1->ToString());
   
   // Get date-only portion of date, without its time.
   DateTime dateOnly = date1->Date;
   // Display date using short date string.
   Console::WriteLine(dateOnly.ToString("d"));
   // Display date using 24-hour clock.
   Console::WriteLine(dateOnly.ToString("g"));
   Console::WriteLine(dateOnly.ToString(L"MM/dd/yyyy HH:mm"));   
}
// The example displays the following output to the console:
//       6/1/2008 7:47:00 AM
//       6/1/2008
//       6/1/2008 12:00 AM
//       06/01/2008 00:00
using System;

public class Example
{
   public static void Main()
   {
      DateTime date1 = new DateTime(2008, 6, 1, 7, 47, 0);
      Console.WriteLine(date1.ToString());
      
      // Get date-only portion of date, without its time.
      DateTime dateOnly = date1.Date;
      // Display date using short date string.
      Console.WriteLine(dateOnly.ToString("d"));
      // Display date using 24-hour clock.
      Console.WriteLine(dateOnly.ToString("g"));
      Console.WriteLine(dateOnly.ToString("MM/dd/yyyy HH:mm"));   
   }
}
// The example displays output like the following output:
//       6/1/2008 7:47:00 AM
//       6/1/2008
//       6/1/2008 12:00 AM
//       06/01/2008 00:00
Module Example
   Public Sub Main()
      Dim date1 As Date = #6/1/2008 7:47AM#
      Console.WriteLine(date1.ToString())
      
      ' Get date-only portion of date, without its time.
      Dim dateOnly As Date = date1.Date
      ' Display date using short date string.
      Console.WriteLine(dateOnly.ToString("d"))
      ' Display date using 24-hour clock.
      Console.WriteLine(dateOnly.ToString("g"))
      Console.WriteLine(dateOnly.ToString("MM/dd/yyyy HH:mm"))   
   End Sub
End Module
' The example displays output like the following:
'       6/1/2008 7:47:00 AM                     
'       6/1/2008
'       6/1/2008 12:00 AM
'       06/01/2008 00:00

注解

返回的 DateTime 值的 Kind 属性的值与当前实例的值相同。The value of the Kind property of the returned DateTime value is the same as that of the current instance.

由于 DateTime 类型表示单个类型中的日期和时间,因此请务必避免将 Date 属性返回的日期错误解释为日期和时间。Because the DateTime type represents both dates and times in a single type, it is important to avoid misinterpreting a date returned by the Date property as a date and time.
