DateTime.Hour 屬性

定義

取得這個執行個體所表示日期的小時元件。

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

屬性值

Int32

小時元件,以 0 到 23 之間的值表示。

範例

下列範例會示範 Hour 屬性。

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

備註

屬性的值 Hour 一律會使用24小時制來表示。 若要使用12小時制來取出代表日期和時間的小時的字串,請 DateTime.ToString(String) DateTime.ToString(String, IFormatProvider) 使用 "h" 自訂格式規範來呼叫或方法。 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
