DateTime.Millisecond 属性

定义

获取此实例所表示日期的毫秒部分。Gets the milliseconds component of the date represented by this instance.

public:
 property int Millisecond { int get(); };
public int Millisecond { get; }
member this.Millisecond : int
Public ReadOnly Property Millisecond As Integer

属性值

毫秒组成部分,表示为 0 和 999 之间的一个值。The milliseconds component, expressed as a value between 0 and 999.

示例

下面的示例演示 Millisecond 属性。The following example demonstrates the Millisecond property.

System::DateTime moment = System::DateTime(
   1999, 1, 13, 3, 57, 32, 11 );

// Year gets 1999.
int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

// Day gets 13.
int day = moment.Day;

// Hour gets 3.
int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;

System.DateTime moment = new System.DateTime(
                                1999, 1, 13, 3, 57, 32, 11);
// Year gets 1999.
int year = moment.Year;

// Month gets 1 (January).
int month = moment.Month;

// Day gets 13.
int day = moment.Day;

// Hour gets 3.
int hour = moment.Hour;

// Minute gets 57.
int minute = moment.Minute;

// Second gets 32.
int second = moment.Second;

// Millisecond gets 11.
int millisecond = moment.Millisecond;
Dim moment As New System.DateTime(1999, 1, 13, 3, 57, 32, 11)

' Year gets 1999.
Dim year As Integer = moment.Year

' Month gets 1 (January).
Dim month As Integer = moment.Month

' Day gets 13.
Dim day As Integer = moment.Day

' Hour gets 3.
Dim hour As Integer = moment.Hour

' Minute gets 57.
Dim minute As Integer = moment.Minute

' Second gets 32.
Dim second As Integer = moment.Second

' Millisecond gets 11.
Dim millisecond As Integer = moment.Millisecond

注解

可以通过使用 "fff" 格式说明符来显示 Millisecond 属性的字符串表示形式。You can display the string representation of the Millisecond property by using the "fff" format specifier. 例如,下面的代码显示一个字符串,其中包含在控制台中的日期和时间的毫秒数。For example, the following code displays a string that contains the number of milliseconds in a date and time to the console.

DateTime date1 = new DateTime(2008, 1, 1, 0, 30, 45, 125);
Console.WriteLine("Milliseconds: {0:fff}", 
                  date1);           // displays Milliseconds: 125
Dim date1 As Date = New Date(2008, 1, 1, 0, 30, 45, 125)
Console.WriteLine("Milliseconds: {0:fff}", _
                  date1)       ' displays Milliseconds: 125

还可以通过使用 "o" 标准格式说明符,与日期和时间值的其他组件一起显示毫秒部分。You can also display the millisecond component together with the other components of a date and time value by using the "o" standard format specifier. 例如:For example:

DateTime date2 = new DateTime(2008, 1, 1, 0, 30, 45, 125);
Console.WriteLine("Date: {0:o}", 
                  date2);           
// Displays the following output to the console:
//      Date: 2008-01-01T00:30:45.1250000
Dim date2 As New Date(2008, 1, 1, 0, 30, 45, 125)
Console.WriteLine("Date: {0:o}", date2)           
' Displays the following output to the console:
'      Date: 2008-01-01T00:30:45.1250000

但是,对于显示,"o" 格式说明符比用于往返或存储 DateTime 值更少。However, the "o" format specifier is intended less for displaying than for round-tripping or storing a DateTime value. 你还可以通过使用自定义格式字符串,与其他日期和时间组件一起显示毫秒,如下面的示例所示。You can also display milliseconds together with other date and time components by using a custom format string, as the following example shows.

DateTime date3 = new DateTime(2008, 1, 1, 0, 30, 45, 125);
Console.WriteLine("Date with milliseconds: {0:MM/dd/yyy HH:mm:ss.fff}", 
                  date3);
// Displays the following output to the console:
//       Date with milliseconds: 01/01/2008 00:30:45.125                       
Dim date3 As New Date(2008, 1, 1, 0, 30, 45, 125)
Console.WriteLine("Date with milliseconds: {0:MM/dd/yyy HH:mm:ss.fff}", _
                  date3)
' Displays the following output to the console:
'       Date with milliseconds: 01/01/2008 00:30:45.125
