如何在.NET中代表一个时间唯一的价值？ [英] How do I represent a time only value in .NET?

问题描述

有没有办法可以代表.NET中的唯一值，而没有日期？例如，指示商店的开放时间？

Is there a way one can represent a time only value in .NET without the date? For example, indicating the opening time of a shop?

TimeSpan 表示一个范围，而我只想存储一个时间值。使用 DateTime 来表示这将导致新的 DateTime（1,1,1,8,30,0）不是真的可取。

TimeSpan indicates a range, whereas I only want to store a time value. Using DateTime to indicate this would result in new DateTime(1,1,1,8,30,0) which is not really desirable.

推荐答案

如其他人所说，您可以使用 DateTime 并忽略日期，或使用 TimeSpan 。就我个人而言，我不喜欢这两种解决方案，因为这两种类型都没有真正反映出你想要表达的概念 - 我认为.NET中的日期/时间类型在稀疏的一面是我开始的原因之一 Noda时间。在Noda时间，您可以使用 LocalTime 类型来表示一天中的时间。

As others have said, you can use a DateTime and ignore the date, or use a TimeSpan. Personally I'm not keen on either of these solutions, as neither type really reflects the concept you're trying to represent - I regard the date/time types in .NET as somewhat on the sparse side which is one of the reasons I started Noda Time. In Noda Time, you can use the LocalTime type to represent a time of day.

有一件事要考虑：一天中的时间不一定是同一天午夜以来的时间长短...

One thing to consider: the time of day is not necessarily the length of time since midnight on the same day...

（另外，如果你还想代表一个关闭商店的时间，您可能会发现您要代表24:00，即一天结束的时间。大多数日期/时间API（包括Noda时间）不允许被表示为日期值。）

(As another aside, if you're also wanting to represent a closing time of a shop, you may find that you want to represent 24:00, i.e. the time at the end of the day. Most date/time APIs - including Noda Time - don't allow that to be represented as a time-of-day value.)
