What is the difference between DateTime.AddDays and Calendar.AddDays?
Is DateTime type calendar independent?

推荐答案

DateTime.AddDays 只是将天数转换为刻度,并将此刻度数添加到日期时间.Calendar.AddDays 的默认实现完全相同.但是,由于它是一种虚拟方法,因此可以以更复杂的方式在特定日历中实现,例如像这里的东西:http://codeblog.jonskeet.uk/2010/12/01/the-joys-of-date-time-arithmetic/

DateTime.AddDays just converts days to ticks and adds this number of ticks to the date time. The default implementation of Calendar.AddDays does exactly the same. However, since it is a virtual method it can be implemented in specific calendar in a more complicated way, e.g. something like here: http://codeblog.jonskeet.uk/2010/12/01/the-joys-of-date-time-arithmetic/
