C＃ - 两个日期之间的差异？ [英] C# - Difference between two dates?

问题描述

我试图计算两个日期之间的差异。这是我目前使用的：

  INT currentyear = DateTime.Now.Year; 
 
现在的DateTime = DateTime.Now; 
的DateTime然后=新日期时间（currentyear，12，26）; 
时间跨度差异=现在 - 那么， 
 INT天= diff.Days; 
 label1.Text = days.ToString（）+天，直到圣诞节; 
  

除了它是一天一切工作正常。我假定这是因为它不指望任何小于一个完整的24小时。有没有办法得到它这样做呢？谢谢你。

解决方案

  INT天数=（int）的Math.Ceiling（diff.TotalDays ）; 
  

I am trying to calculate the difference between two dates. This is what I'm currently using:

int currentyear = DateTime.Now.Year;

DateTime now = DateTime.Now;
DateTime then = new DateTime(currentyear, 12, 26);
TimeSpan diff = now - then;
int days = diff.Days;
label1.Text = days.ToString() + " Days Until Christmas";

All works fine except it is a day off. I am assuming this is because it does not count anything less than 24 hours a complete day. Is there a way to get it to do so? Thank you.

解决方案

int days = (int)Math.Ceiling(diff.TotalDays);
