不要。

您可以编写一个正则表达式来验证日期： http：//www.regular-expressions .info / dates.html [ ^ ] ...但这对于问题来说是一个糟糕的解决方案。



相反，使用 DateTime.TryParseExact [ ^ ]这样更容易阅读，甚至可以将其转换为DateTime值供您使用将来！

Don't.
You can write a regex to validate a date: http://www.regular-expressions.info/dates.html[^]...but it's a poor solution to teh problem.

Instead, use DateTime.TryParseExact[^] which is a lot easier to read, and even converts it to a DateTime value for you to use in future!
