示例

下面的示例演示了 Hour 属性。

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

Hour始终使用24小时制表示属性的值。 若要使用12小时制检索表示日期和时间的小时的字符串，请使用 DateTime.ToString(String) DateTime.ToString(String, IFormatProvider) "h" 自定义格式说明符调用或方法。 例如：

DateTime date1 = new DateTime(2008, 4, 1, 18, 53, 0);
Console.WriteLine(date1.ToString("%h"));              // Displays 6
Console.WriteLine(date1.ToString("h tt"));            // Displays 6 PM

Dim date1 As Date = #04/01/2008 6:53:00PM#
Console.WriteLine(date1.ToString("%h"))      ' Displays 6
Console.WriteLine(date1.ToString("h tt"))    ' Displays 6 PM
