What is the difference between DateTime.AddDays and Calendar.AddDays?Is DateTime type calendar independent?
推荐答案
DateTime.AddDays只是转换天内蜱和蜱添加的日期时间超过此数目。 Calendar.AddDays的默认实现不完全一样的。然而，由于它是一个虚拟方法，可以在特定的日历在一个更复杂的方式，例如，实施像这里： HTTP：/ /$c$cblog.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/
