설명

TimeZoneInfo.AdjustmentRule 클래스 정의 유효한 시작 및 일광 절약 시간에서이 특정 시간 변경 된 종료 날짜를 각각 해당 델타 및 (조정 인해 변경 하려면 해당 표준 시간대의 표준 시간 정확한 크기).The TimeZoneInfo.AdjustmentRule class defines the effective start and end dates of a particular time change to and from daylight saving time, respectively, as well as its delta (the exact amount by which the adjustment causes the time zone's standard time to change). 또한 두 개의 속성을 반환할 TimeZoneInfo.TransitionTime 표준 시간에서 각 전환이 발생 하는 경우 정의 하는 개체입니다.In addition, two properties return TimeZoneInfo.TransitionTime objects that define when each transition to and from standard time occurs.

만들려는 TimeZoneInfo.AdjustmentRule 개체를 호출 합니다 static (Shared Visual Basic에서) TimeZoneInfo.AdjustmentRule.CreateAdjustmentRule 메서드.To create a TimeZoneInfo.AdjustmentRule object, call the static (Shared in Visual Basic) TimeZoneInfo.AdjustmentRule.CreateAdjustmentRule method. 배열의 제공할 수 있습니다 TimeZoneInfo.AdjustmentRule 오버 로드 중 두 개체는 TimeZoneInfo.CreateCustomTimeZone 메서드.You can then supply an array of TimeZoneInfo.AdjustmentRule objects to two of the overloads of the TimeZoneInfo.CreateCustomTimeZone method. 특정 표준 시간대의 조정 규칙을 검색 하려면 해당 TimeZoneInfo.GetAdjustmentRules 배열을 반환 하는 메서드 TimeZoneInfo.AdjustmentRule 개체입니다.To retrieve the adjustment rules of a particular time zone, call its TimeZoneInfo.GetAdjustmentRules method, which returns an array of TimeZoneInfo.AdjustmentRule objects.
