DateTime dt = DateTime.Parse("3/13/2016 2:41:00 AM");
DateTime Date_Time = TimeZoneInfo.ConvertTimeBySystemTimeZoneId(dt,"Eastern Standard Time","GMT Standard Time");
Response.Write(dt);
执行后,我收到此错误：
The supplied DateTime represents an invalid time. For example,when@H_301_8@ the clock is adjusted forward,any time in the period that is skipped@H_301_8@ is invalid. Parameter name: dateTime
解决方法
2016 Sun,13 Mar,02:00 CST → CDT +1 hour (DST start) UTC-5h
Sun,6 Nov,02:00 CDT → CST -1 hour (DST end) UTC-6h

System.TimeZoneInfo (currently available as part of .NET Framework 3.5@H_301_8@ Beta 1) contains methods for checking if a DateTime instance@H_301_8@ represents an ambiguous or invalid time in a specific time zone. These@H_301_8@ methods are particularly useful for validating user-supplied points in@H_301_8@ time.
Background Information
Time zones that adjust their time for Daylight Saving Time (in most@H_301_8@ cases by moving the clock time back or forward by 1 hour) have gaps@H_301_8@ and repeats in the timeline — wherever the clock time was moved@H_301_8@ forward or back by the adjustment. Let’s use Pacific Standard Time as@H_301_8@ an example. In 2007 Pacific Standard Time (PST) changes to Pacific@H_301_8@ Daylight Time (PDT) at 02:00AM (“spring forward”) on the second Sunday@H_301_8@ in March and then returns at 02:00AM (“fall back”) on the first Sunday@H_301_8@ in November
