总毫秒数 [英] Total number of millseconds

问题描述

嘿伙计们，我想找到两次之间的总毫秒数。我第一次进行转换以输入正确的格式，然后我继续进行计算。然而，我的结果如果非常小，我似乎无法找出什么是错的。

Hey guys i want to find the total number of milliseconds between 2 time. I do a conversion on the first time to put in the correct format, then i proceed to to the calculation. However my result if very small and i can't seem to find out whats wrong.

   string dateValues =  "10042011" ;
   string pattern = "MMddyyyy";
   DateTime parsedDate=new DateTime();


if (DateTime.TryParseExact(dateValues, pattern, null, DateTimeStyles.None, out parsedDate))
  {
       Console.WriteLine("Converted to this: " + parsedDate);
   }

   DateTime d1 = parsedDate;
   DateTime d2 = new DateTime(1970, 1, 1);

   TimeSpan ts = new TimeSpan(d1.Ticks - d2.Ticks);


   Console.WriteLine("Converted to this: " + ts);

输出为：15982.00：00：00，我非常确定这不正确。



感谢您的帮助

the output is : 15982.00:00:00, and i am very sure this not correct.

thanks for your help

推荐答案

使用 System.TimeSpan.TotalMilliseconds ：

-SA

删除新东西 - 两个DateTime对象之间的差异已经是Timespan：

Drop the new stuff - the difference between two DateTime objects is a Timespan already:

TimeSpan ts = d1 - d2;
Console.WriteLine("Converted to this: " + ts.TotalMilliseconds);

你的代码看起来......好吧......如果你拿一个日期并从中减去一个日期，你会得到一个TimeSpan对象，不是约会。您不必创建新的Timespan。您的代码应该更接近：

Your code looks... well... If you take a date and subtract a date from it, you get a TimeSpan object back, not a date. You don't have to create a new Timespan. Your code should be closer to:

DateTime beginDate = new DateTime(1970, 1, 1);
DateTime endDate = DateTime.Now;

TimeSpan difference = endDate - beginDate;

Debug.WriteLine(difference.TotalMilliseconds);
