備註

如果產生的日期不是結果年份結果月份的有效日期，則產生的 DateTime 日期部分會受到影響。 它會變更為結果年份結果月份的最後一個有效日。 結果 DateTime 的月份部分會維持與指定的 DateTime 相同。 此實作僅支援目前的紀元。 因此， ArgumentException 如果產生的年份超出指定的 DateTime 紀元，則會擲回 。 結果 DateTime 的當日時間部分會維持與指定的 DateTime 相同。

例如，2 月有 28 天，但閏年有 29 天除外。 如果指定的日期是閏年 2 月的第 29 天，而 的值 years 是 1，則產生的日期會是下一年 2 月的第 28 天。

如果 years 為負數，則產生的 DateTime 會早于指定的 DateTime 。

傳 Kind 回 DateTime 值的 屬性一律等於 DateTimeKind.Unspecified 。 您可以呼叫 DateTime.SpecifyKind 方法來保留 Kind 參數的 time 屬性，如下列範例所示。

returnTime = DateTime.SpecifyKind(cal.AddYears(time, years), time.Kind);

returnTime = DateTime.SpecifyKind(cal.AddYears(time, years), time.Kind)
