public:
 static TimeZoneInfo::AdjustmentRule ^ CreateAdjustmentRule(DateTime dateStart, DateTime dateEnd, TimeSpan daylightDelta, TimeZoneInfo::TransitionTime daylightTransitionStart, TimeZoneInfo::TransitionTime daylightTransitionEnd);

public static TimeZoneInfo.AdjustmentRule CreateAdjustmentRule (DateTime dateStart, DateTime dateEnd, TimeSpan daylightDelta, TimeZoneInfo.TransitionTime daylightTransitionStart, TimeZoneInfo.TransitionTime daylightTransitionEnd);

Public Shared Function CreateAdjustmentRule (dateStart As DateTime, dateEnd As DateTime, daylightDelta As TimeSpan, daylightTransitionStart As TimeZoneInfo.TransitionTime, daylightTransitionEnd As TimeZoneInfo.TransitionTime) As TimeZoneInfo.AdjustmentRule

参数

dateStart: DateTime

调整规则的生效日期。如果 dateStart 参数的值为 DateTime.MinValue.Date，那么这是时区的第一个有效的调整规则。

dateEnd: DateTime

执行调整规则的最后日期。如果 dateEnd 参数的值为 DateTime.MaxValue.Date，则调整规则无结束日期。

daylightDelta: TimeSpan

调整所产生的时间更改。将该值添加到时区的 BaseUtcOffset 属性，以便获取从协调世界时 (UTC) 开始的正确的夏令时偏移量。该值的范围介于 -14 到 14。

daylightTransitionStart: TimeZoneInfo.TransitionTime

定义夏令时的开始时间的对象。

daylightTransitionEnd: TimeZoneInfo.TransitionTime

定义夏令时的结束时间的对象。

TimeZoneInfo.AdjustmentRule

表示新调整规则的对象。

例外

ArgumentException

参数 dateStart 或 dateEnd 的属性 Kind 的值不等于 Unspecified。

- 或 -

daylightTransitionStart 参数等于 daylightTransitionEnd 参数。

- 或 -

dateStart 或 dateEnd 参数包含一个日期的时间值。

ArgumentOutOfRangeException

dateEnd 早于 dateStart。

- 或 -

daylightDelta 小于 -14 或大于 14。

- 或 -

daylightDelta 参数的 Milliseconds 属性不等于 0。

- 或 -

daylightDelta 参数的 Ticks 属性不等于整秒数。

示例

以下示例创建备用的中央标准时区，并为 1976-1986 年、1987-2006 年和 2007 年及以后的时间段定义三个调整规则。这些规则将添加到一个泛型 List<T> 对象，该对象的元素随后将复制到 TimeZoneInfo.AdjustmentRule 数组中。然后，在调用 TimeZoneInfo.CreateCustomTimeZone(String, TimeSpan, String, String, String, TimeZoneInfo+AdjustmentRule[]) 方法时使用此数组。

// Create alternate Central Standard Time to include historical time zone information
//
// Declare necessary TimeZoneInfo.AdjustmentRule objects for time zone
TimeSpan delta = new TimeSpan(1, 0, 0);
TimeZoneInfo.AdjustmentRule adjustment;
List<TimeZoneInfo.AdjustmentRule> adjustmentList = new List<TimeZoneInfo.AdjustmentRule>();
// Declare transition time variables to hold transition time information
TimeZoneInfo.TransitionTime transitionRuleStart, transitionRuleEnd;

// Define end rule (for 1976-2006)
transitionRuleEnd = TimeZoneInfo.TransitionTime.CreateFloatingDateRule(new DateTime(1, 1, 1, 2, 0, 0), 10, 5, DayOfWeek.Sunday);
// Define rule (1976-1986)

注解

可以使用此方法为自定义时区创建一个或多个调整规则。然后，可以通过调用此方法返回的对象的数组 TimeZoneInfo.AdjustmentRule 作为 adjustmentRules 参数传递给方法的 CreateCustomTimeZone 两个重载。该示例演示了此过程。

备注

方法 CreateAdjustmentRule 只能用于定义新时区的调整规则;不能用于修改现有时区的调整规则。

dateStart和 dateEnd 参数必须是没有时间组件的日期值，否则ArgumentException会引发。可以通过从日期和时间的属性中检索值 DateTime 来删除时间 Date 部分，如以下语句所示：

DateTime.MinValue.Date  
DateTime.MaxValue.Date  
DateTime.Now.Date   
dateVariable.Date

Kind和 dateEnd 参数的 dateStart 属性也必须是 DateTimeKind.Unspecified。

参数的值 daylightDelta 范围为 -14 到 14。参数和调用方法中使用的TimeZoneInfo.CreateCustomTimeZone参数之和daylightDeltabaseUtcOffset也必须介于 -14 到 14 的范围内，否则InvalidTimeZoneException会引发。

注意

daylightDelta参数定义时区的标准时间与其夏令时之间的差异。它不打算定义时区的标准时间偏移量与协调世界时 (UTC) 。类 TimeZoneInfo 假定与 UTC 的此偏移量在时区的整个生命周期内都是恒定的。若要反映时区相对于 UTC 的偏移量（不是由应用调整规则引起的）的更改，必须使用 CreateCustomTimeZone 方法来创建新的自定义时区。

参数

dateStart: DateTime

调整规则的生效日期。如果值为 DateTime.MinValue.Date，则这是对时区生效的第一个调整规则。

dateEnd: DateTime

执行调整规则的最后日期。如果值为 DateTime.MaxValue.Date，则调整规则没有结束日期。

daylightDelta: TimeSpan

调整所产生的时间更改。此值将添加到时区的 BaseUtcOffset 和 BaseUtcOffsetDelta 属性中，以从协调世界时 (UTC) 获取正确的夏令时偏移量。该值的范围介于 -14 到 14。

daylightTransitionStart: TimeZoneInfo.TransitionTime

夏令时开始。

daylightTransitionEnd: TimeZoneInfo.TransitionTime

夏令时结束。

baseUtcOffsetDelta: TimeSpan

调整规则期间时区的基本 UTC 偏移量的时间差。

TimeZoneInfo.AdjustmentRule

新的调整规则。
