TimeZoneInfo.TransitionTime.CreateFixedDateRule 方法

定義

定義使用固定日期規則的時間變更 (也就是在特定月份的特定日期發生的時間變更)。

public:
 static TimeZoneInfo::TransitionTime CreateFixedDateRule(DateTime timeOfDay, int month, int day);
public static TimeZoneInfo.TransitionTime CreateFixedDateRule (DateTime timeOfDay, int month, int day);
static member CreateFixedDateRule : DateTime * int * int -> TimeZoneInfo.TransitionTime
Public Shared Function CreateFixedDateRule (timeOfDay As DateTime, month As Integer, day As Integer) As TimeZoneInfo.TransitionTime

參數

timeOfDay
DateTime

發生時間變更的時間。 這個參數會對應至 TimeOfDay 屬性。

month
Int32

發生時間變更的月份。 這個參數會對應至 Month 屬性。

day
Int32

發生時間變更的月份日期。 這個參數會對應至 Day 屬性。

傳回

TimeZoneInfo.TransitionTime

時間變更的相關資料。

例外狀況

timeOfDay 參數具有非預設的日期元件。

-或- timeOfDay 參數的 Kind 屬性不是 Unspecified

-或- timeOfDay 參數不表示整數毫秒數。

month 參數小於 1 或大於 12。

-或- day 參數小於 1 或大於 31。

範例

下列範例會使用固定日期規則和浮點數規則,為虛時區建立時區轉換。 固定日期規則會定義從上午 2:00 開始的時區調整。 于 3 月 15 日結束于上午 3:00 1900 年到 1955 年 11 月 15 日。

備註

此方法會建立固定日期規則 (,也就是在特定月份的特定日期) 發生的時間變更。 例如,一律發生在 10 月 28 日的時間變更遵循固定日期規則。

針對從標準時間轉換為日光節約時間,自 timeOfDay 變數代表時區標準時間中的轉換時間。 對於從日光節約時間轉換為標準時間的轉換,它代表時區日光節約時間中的轉換時間。 請注意,這是年份 DateTime 、月和日期值必須全部等於 1 的值。
