两个日期之间的天数差异 [英] Difference in days between two dates

问题描述

我如何获得两个日期之间的区别?
示例:
2011/10/10
2011/10/12
-----------
日:2

注意:29天和31天用于计算

解决方案

您可以使用TimeSpan来检索差异.考虑以下示例:

 DateTime startDate = DateTime.Now.AddDays(-25);
DateTime endDate = DateTime.Now;
TimeSpan差异= endDate.Subtract(startDate);
Console.WriteLine(difference.Days); 

使用DateTime.Subtract(DateTime) 函数.

 DateTime圣诞节= 新 DateTime( 2011 ， 10 )；
DateTime newYears = 新 DateTime( 2011 ， 10 ， 12 );
TimeSpan span = newYears.Subtract(christmas);

console.Writeline(span);

You use a TimeSpan to retrieve the difference. Consider this example:

DateTime startDate = DateTime.Now.AddDays(-25);
DateTime endDate = DateTime.Now;
TimeSpan difference = endDate.Subtract(startDate);
Console.WriteLine(difference.Days);

Use DateTime.Subtract(DateTime) function.

DateTime christmas = new DateTime(2011, 10, 10);
DateTime newYears = new DateTime(2011, 10, 12);
TimeSpan span = newYears.Subtract(christmas);

console.Writeline(span);
