如何知道DateTime是否在C#中的DateRange之间 [英] How to know if a DateTime is between a DateRange in C#

问题描述

我需要知道日期是否介于 DateRange 之间.我有三个日期:

I need to know if a Date is between a DateRange. I have three dates:

// The date range
DateTime startDate;
DateTime endDate;

DateTime dateToCheck;

简单的解决方案是进行比较，但有没有更聪明的方法来做到这一点?

The easy solution is doing a comparison, but is there a smarter way to do this?

推荐答案

不，做一个简单的比较对我来说很好:

Nope, doing a simple comparison looks good to me:

return dateToCheck >= startDate && dateToCheck < endDate;

需要考虑的事情:

• DateTime 在时区方面有点奇怪.它可能是UTC，可能是本地"，也可能是模棱两可的.确保您将苹果与苹果进行比较.
• 考虑您的起点和终点应该是包容性的还是排斥性的.我已经让上面的代码把它当作一个包含下限和一个排他上限.

• DateTime is a somewhat odd type in terms of time zones. It could be UTC, it could be "local", it could be ambiguous. Make sure you're comparing apples with apples, as it were.
• Consider whether your start and end points should be inclusive or exclusive. I've made the code above treat it as an inclusive lower bound and an exclusive upper bound.
