例

Yearプロパティの例を次に示します。

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;

open System


let moment = System.DateTime(1999, 1, 13, 3, 57, 32, 11)

// Year gets 1999.
let year = moment.Year

// Month gets 1 (January).
let month = moment.Month

// Day gets 13.
let day = moment.Day

// Hour gets 3.
let hour = moment.Hour

// Minute gets 57.
let minute = moment.Minute

// Second gets 32.
let second = moment.Second

// Millisecond gets 11.
let 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

注釈

プロパティは Year 、グレゴリオ暦の現在のインスタンスの年を返します。 現在のカルチャの既定のカレンダーを使用して年が返されることはありません。 特定のカレンダーを使用して年を取得するには、次のコードに示すように、そのカレンダーの GetYear メソッドを呼び出すことができます。

      Console.WriteLine(date1.Year);                    // Displays 2008

      // Set culture to th-TH
      Thread.CurrentThread.CurrentCulture = new CultureInfo("th-TH");
      Console.WriteLine(date1.Year);                    // Displays 2008

      // display year using current culture's calendar
      Calendar thaiCalendar = CultureInfo.CurrentCulture.Calendar;
      Console.WriteLine(thaiCalendar.GetYear(date1));   // Displays 2551
