DateTime差异恢复正确的月份甚至几年？ [英] DateTime difference returing correct no of months and or even years?

问题描述

有没有任何内置函数，如何以更好的方式获得thoTimeTime对象之间的差异，而不仅仅是天数？我的意思是像1个月23天。我觉得很难计算，因为每个月的闰天数不同，闰年等。
谢谢

解决方案

看看 Noda时间。它并不是一般的生产准备，但相关的位可能适用于您当前的要求：）

请注意， TimeSpan 将不做你想要的，因为1个月可能意味着不同的天数取决于月份，而$ code> TimeSpan 不锚定。

在Noda时间，您需要一个期间。例如：

  LocalDate start = new LocalDate（2010,4,15）; 
 LocalDate end = new LocalDate（2010,6,19）; 
期间= Period.Between（开始，结束）; //默认为年/月/日
 
 Console.WriteLine（period.Months）; // 2 
 Console.WriteLine（period.Days）; // 4 
  

请注意，日期/时间算术很难 ...在某些情况下正确的答案不太明显。

Is there any built-in function how can I get the difference between tho DateTime objects in better way than just number of days? I mean something like 1 month, 23 days. I find it pretty hard to calculate due to differnet number of days in each month, leap years etc. Thanks

解决方案

Have a look at Noda Time. It's not production-ready in general yet, but the relevant bits may work well enough for your current requirements :)

Note that TimeSpan will not do what you want, because "1 month" can mean a different number of days depending on the month, and a TimeSpan isn't anchored.

In Noda Time, you want a Period. For example:

LocalDate start = new LocalDate(2010, 4, 15);
LocalDate end = new LocalDate(2010, 6, 19);
Period period = Period.Between(start, end); // Defaults to Year/Month/Day

Console.WriteLine(period.Months); // 2
Console.WriteLine(period.Days); // 4

Note that date/time arithmetic is hard... in some cases "the right answer" isn't at all obvious.
