获取发生夏时制过渡的下一个日期/时间 [英] Get the next date/time at which a daylight savings time transition occurs

问题描述

我想在C＃中编写（或使用它已经退出的情况）一个函数，该函数在给定 System.TimeZoneInfo 对象以及该时区中的特定开始时间。返回的时间应在提供的时区中。我想要的函数具有以下签名：

I would like to write (or use if it already exits) a function in C# that returns the date/time of the next DST transition given a System.TimeZoneInfo object and a particular "as of" time in that time zone. The time returned should be in the provided time zone. The function I want has this signature:

public DateTime GetNextTransition(DateTime asOfTime, TimeZoneInfo timeZone)
{
    // Implement me!
}

例如，如果我传入东部标准时间 TimeZoneInfo对象，和1/21/2011 @ 17：00作为 asOfTime，我希望此函数返回3/13/2011 @ 2：00。

For example, if I pass in the "Eastern Standard Time" TimeZoneInfo object, and 1/21/2011@17:00 as the "asOfTime", I expect this function to return 3/13/2011@2:00.

href = http://msdn.microsoft.com/zh-cn/library/system.timezoneinfo.transitiontime.aspx> System.TimeZoneInfo.TransitionTime 结构似乎具有我需要的所有信息，但理想的情况是是某种将规则转换为实际日期的内置机制。有人有任何建议吗？

The System.TimeZoneInfo.TransitionTime structure appears to have all the information I need, but ideally there would be some sort of built-in mechanism to convert the rule into an actual date. Anyone have any suggestions?
