Hourプロパティの例を次に示します。The following example demonstrates the Hour property.

1999, 1, 13, 3, 57, 32, 11 );

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.

注釈

Hour プロパティの値は、常に24時間制を使用して表されます。The value of the Hour property is always expressed using a 24-hour clock. 12時間制を使用して日時の時刻を表す文字列を取得するには、"h" カスタム書式指定子を使用して、DateTime.ToString(String) または DateTime.ToString(String, IFormatProvider) メソッドを呼び出します。To retrieve a string that represents the hour of a date and time using a 12-hour clock, call the DateTime.ToString(String) or DateTime.ToString(String, IFormatProvider) method with the "h" custom format specifier. 次に例を示します。For example:

``````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
``````
