日期年月计算

Question

我有形式的两个日期：

Start Date: 2007-03-24 
End Date: 2009-06-26 

现在我需要找到以下形式这两者之间的区别：

2 years, 3 months and 2 days 

我该怎么做在C＃窗体的形式？

Answer 1

您需要使用TimeSpan获得差异..

class Program 
    { 
     static void Main(string[] args) 
     { 

      string StartDate = "2007-03-24"; 
      string EndDate = "2009-06-26"; 

      System.DateTime firstDate = DateTime.ParseExact(StartDate, "yyyy-MM-dd", System.Globalization.CultureInfo.InvariantCulture); 
      System.DateTime secondDate = DateTime.ParseExact(EndDate, "yyyy-MM-dd", System.Globalization.CultureInfo.InvariantCulture); 

      System.TimeSpan diff = secondDate.Subtract(firstDate); 
      var totalDays = (diff).TotalDays; 
      var totalYears = Math.Truncate(totalDays/365); 
      var totalMonths = Math.Truncate((totalDays % 365)/30); 
      var remainingDays = Math.Truncate((totalDays % 365) % 30); 
      Console.WriteLine("Estimated duration is {0} year(s), {1} month(s) and {2} day(s)", totalYears, totalMonths, remainingDays); 
      Console.ReadLine(); 

     } 

    }
