推荐答案

好像要减去两个DateTime而不是 add .减去将得出一个TimeSpan，它代表一个间隔.您可以添加TimeSpans.
将星期一12:15 添加到星期二09:45 没有意义，但是将 1天3小时添加到 2小时45分钟确实有意义.从星期二07:15 减去星期一23:00 确实是有道理的，应该给 8小时15分钟，这是一个TimeSpan.您可以添加一个DateTime和一个TimeSpan来获取另一个DateTime(星期一18:00 + 11小时给出星期二05:00 .)
谷歌搜索减去DateTime"直接进入MSDN，您需要了解的所有信息.

Looks like you want to subtract two DateTimes rather than add them. Subtracting gives a TimeSpan, which represents an interval. You can add TimeSpans.
Adding Monday 12:15 to Tuesday 09:45 doesn''t make sense, but adding 1 day, 3 hours to 2 hours 45 minutes does make sense. Subtracting Monday 23:00 from Tuesday 07:15 does make sense, and should give 8 hours 15 minutes, which is a TimeSpan. You can add a DateTime and a TimeSpan to get another DateTime (Monday 18:00 + 11 hours gives Tuesday 05:00.)
Googling "subtract DateTime" goes straight to MSDN with all you need to know.
