问题描述
我有一个用户可以配置在非高峰时段运行的服务。他们有规定的时限，该服务可以运行的能力。
I have a service that user can configure to run during "off-peak" hours. They have the ability to set the time frame that the service can run.
例如：
用户A的工作原理8点至晚5，所以他们要安排应用至下午5:30和7:30之间运行。
User A works 8am-5pm, so they want to schedule the app to run between 5:30pm and 7:30am.
用户B工作9 pm-6am，所以他们安排应用上午6:30和下午8:30之间运行。
User B works 9pm-6am, so they schedule the app to run between 6:30am and 8:30 pm.
问题的关键是，虽然他们不是应用程序使用他们的计算机。
The point is that the app uses their computer while they are not.
鉴于当前时间的日期时间，开始日期时间和停止时间的DateTime，我怎么能检查电流之间开始和停止。
Given a DateTime of the current time, a DateTime of the start and a DateTime of the stop time, how can I check if current is between start and stop.
对于我来说最棘手的部分是时间可以跨午夜边界。
The tricky part for me is that the time can cross the midnight boundary.
推荐答案
如果的startTime 和结束时间重新present一个单一的时间间隔（它只会发生一次，而的startTime 和结束时间重新present日期和启动/停止的时间），那么它的话说
If startTime and endTime represent a single time interval (it will only happen once, and startTime and endTime represent the date and the time to start/stop), then it's as easy as saying
bool isTimeBetween = someTime >= startTime && someTime <= endTime;
如果这是一个反复出现的事件（每天都是这样，有的间隔内），您可以使用做比较的<$c$c>TimeOfDay属性。 （反复出现的情况是一个，你必须考虑的一个开始/停止跨越午夜）
If it's a recurring event (happens every day, during some interval), you can do comparisons using the TimeOfDay property. (The recurring case is the one where you have to consider a start/stop that crosses midnight)
static public bool IsTimeOfDayBetween(DateTime time,
TimeSpan startTime, TimeSpan endTime)
{
if (endTime == startTime)
{
return true;
}
else if (endTime < startTime)
{
return time.TimeOfDay <= endTime ||
time.TimeOfDay >= startTime;
}
else
{
return time.TimeOfDay >= startTime &&
time.TimeOfDay <= endTime;
}
}
（注：此code假定，如果开始==结束，那么它涵盖了所有次你做了一个评论在另一个帖子这个效果。）
(Note: This code assumes that if start == end, then it covers all times. You made a comment to this effect on another post)
例如，要检查它是否是上午5点和下午9:30之间
For example, to check if it's between 5 AM and 9:30 PM
IsTimeOfDayBetween(someTime, new TimeSpan(5, 0, 0), new TimeSpan(21, 30, 0))
如果的startTime 和结束时间是的DateTime S，你可以说
If startTime and endTime are DateTimes, you could say
IsTimeOfDayBetween(someTime, startTime.TimeOfDay, endTime.TimeOfDay)
