TaiwanCalendar.AddYears メソッド
アセンブリ: mscorlib (mscorlib.dll 内)

Dim instance As TaiwanCalendar Dim time As DateTime Dim years As Integer Dim returnValue As DateTime returnValue = instance.AddYears(time, years)
戻り値
指定した DateTime に指定した年数を加算した結果の DateTime。


結果として得られる日が結果の年の結果の月に対して有効な日でない場合は、結果として得られる DateTime の日付部分が影響を受けます。この日付は、結果の年の結果の月にとって有効な最後の日付に変更されます。結果として得られる DateTime の月の部分は、指定した DateTime の値と同じままです。この実装では現在の時代 (年号) だけをサポートしています。したがって、結果として得られた年が、指定された DateTime の時代 (年号) の範囲外の場合、ArgumentException がスローされます。結果として得られる DateTime の時刻の部分は、指定した DateTime の値と同じままです。
たとえば、2 月の日数は 28 日ですが、閏年の場合は 29 日になります。指定した日付が閏年の 2 月 29 日で years の値が 1 の場合、結果として得られる日付は翌年の 2 月 28 日になります。

DateTime のいくつかのコンポーネントの値を台湾暦で表示する例を次に示します。
