Hinweise

Die TimeZoneInfo.AdjustmentRule -Klasse definiert die effektive Start- und Enddatum der einen bestimmten Zeitwechsel in und aus der Sommerzeit, sowie das Delta (die genaue Größe, mit dem wird die Anpassung Normalzeit der Zeitzone, zu ändern).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). Darüber hinaus zwei Eigenschaften zurückgeben TimeZoneInfo.TransitionTime Objekte, die definieren, wenn der Übergangs zu und von Standardzeit auftritt.In addition, two properties return TimeZoneInfo.TransitionTime objects that define when each transition to and from standard time occurs.

Hinweis

Eine Instanz von der TimeZoneInfo.AdjustmentRule Klasse ist unveränderlich.An instance of the TimeZoneInfo.AdjustmentRule class is immutable. Nachdem ein Objekt erstellt wurde, werden nicht die Werte geändert.Once an object has been created, its values cannot be modified.

Zum Erstellen einer TimeZoneInfo.AdjustmentRule Objekt, rufen Sie die static (Shared in Visual Basic) TimeZoneInfo.AdjustmentRule.CreateAdjustmentRule Methode.To create a TimeZoneInfo.AdjustmentRule object, call the static (Shared in Visual Basic) TimeZoneInfo.AdjustmentRule.CreateAdjustmentRule method. Sie können dann angeben, ein Array von TimeZoneInfo.AdjustmentRule zu zwei der Überladungen der Objekte die TimeZoneInfo.CreateCustomTimeZone Methode.You can then supply an array of TimeZoneInfo.AdjustmentRule objects to two of the overloads of the TimeZoneInfo.CreateCustomTimeZone method. Rufen Sie zum Abrufen der Anpassungsregeln einer Zeitzone die TimeZoneInfo.GetAdjustmentRules Methode, die ein Array von zurückgibt TimeZoneInfo.AdjustmentRule Objekte.To retrieve the adjustment rules of a particular time zone, call its TimeZoneInfo.GetAdjustmentRules method, which returns an array of TimeZoneInfo.AdjustmentRule objects.

Eigenschaften

DateEnd DateEnd DateEnd DateEnd

Ruft das Datum ab, an dem die Gültigkeit der Anpassungsregel endet.Gets the date when the adjustment rule ceases to be in effect.

DateStart DateStart DateStart DateStart

Ruft das Datum ab, zu dem die Anpassungsregel wirksam wird.Gets the date when the adjustment rule takes effect.

DaylightDelta DaylightDelta DaylightDelta DaylightDelta

Ruft die Länge des Zeitraums ab, aus dem die Sommerzeit der Zeitzone besteht.Gets the amount of time that is required to form the time zone's daylight saving time. Dieser Zeitraum wird zum Offset der Zeitzone von der Coordinated Universal Time (UTC) addiert.This amount of time is added to the time zone's offset from Coordinated Universal Time (UTC).

DaylightTransitionEnd DaylightTransitionEnd DaylightTransitionEnd DaylightTransitionEnd

Ruft Informationen über den jährlichen Wechsel von der Sommerzeit zurück zur Standardzeit ab.Gets information about the annual transition from daylight saving time back to standard time.

DaylightTransitionStart DaylightTransitionStart DaylightTransitionStart DaylightTransitionStart

Ruft Informationen über den jährlichen Wechsel von der Standardzeit zurück zur Sommerzeit ab.Gets information about the annual transition from standard time to daylight saving time.
