取得目前 DateTimeOffset 物件所表示之日期的年份元件。

public:
 property int Year { int get(); };

public int Year { get; }

member this.Year : int

Public ReadOnly Property Year As Integer

屬性值

Int32

目前 DateTimeOffset 物件的年份元件，以 0 到 9999 之間的整數表示。

範例

下列範例會以四種不同的方式顯示值的年份元件 DateTimeOffset ：

• 藉由擷取 屬性的值 Year 。

• 使用 「y」 格式規範呼叫 ToString(String) 方法。

• 使用 「yy」 格式規範呼叫 ToString(String) 方法。

• 使用 「yyyy」 格式規範呼叫 ToString(String) 方法。

DateTimeOffset theTime = new DateTimeOffset(2008, 2, 17, 9, 0, 0,
                             DateTimeOffset.Now.Offset);
Console.WriteLine("The year component of {0} is {1}.",
                  theTime, theTime.Year);

Console.WriteLine("The year component of {0} is{1}.",
                  theTime, theTime.ToString(" y"));

Console.WriteLine("The year component of {0} is {1}.",
                  theTime, theTime.ToString("yy"));

Console.WriteLine("The year component of {0} is {1}.",
                  theTime, theTime.ToString("yyyy"));
// The example produces the following output:
//    The year component of 2/17/2008 9:00:00 AM -07:00 is 2008.
//    The year component of 2/17/2008 9:00:00 AM -07:00 is 8.
//    The year component of 2/17/2008 9:00:00 AM -07:00 is 08.
//    The year component of 2/17/2008 9:00:00 AM -07:00 is 2008.

let theTime = DateTimeOffset(2008, 2, 17, 9, 0, 0, DateTimeOffset.Now.Offset)
printfn $"The year component of {theTime} is {theTime.Year}."

printfn $"""The year component of {theTime} is{theTime.ToString " y"}."""

printfn $"The year component of {theTime} is {theTime:yy}."

printfn $"The year component of {theTime} is {theTime:yyyy}."

// The example produces the following output:
//    The year component of 2/17/2008 9:00:00 AM -07:00 is 2008.
//    The year component of 2/17/2008 9:00:00 AM -07:00 is 8.
//    The year component of 2/17/2008 9:00:00 AM -07:00 is 08.
//    The year component of 2/17/2008 9:00:00 AM -07:00 is 2008.

Dim theTime As New DateTimeOffset(#2/17/2008 9:00AM#, _
                                  DateTimeOffset.Now.Offset)
Console.WriteLine("The year component of {0} is {1}.", _
                  theTime, theTime.Year)

Console.WriteLine("The year component of {0} is{1}.", _
                  theTime, theTime.ToString(" y"))

Console.WriteLine("The year component of {0} is {1}.", _
                  theTime, theTime.ToString("yy"))
                  
Console.WriteLine("The year component of {0} is {1}.", _
                  theTime, theTime.ToString("yyyy"))
' The example produces the following output:
'    The year component of 2/17/2008 9:00:00 AM -07:00 is 2008.
'    The year component of 2/17/2008 9:00:00 AM -07:00 is 8.
'    The year component of 2/17/2008 9:00:00 AM -07:00 is 08.
'    The year component of 2/17/2008 9:00:00 AM -07:00 is 2008.

備註

屬性 Year 不會受到 屬性的值 Offset 影響。

您也可以使用 「y」、「yyy」 或 「yy」 自訂格式規範呼叫 方法來建立 ToString 物件的年份元件字串表示 DateTimeOffset 。
