在C＃中获取时间差的时间差 [英] To take time difference in timespan in C#

问题描述

Iam开发计时器应用程序，我已经创建了计时器，并希望在HH：MM：SS两个时间的差异，从我这边，秒解决方案工作完美，但我无法正确得到分钟。



例如：time1：18：41：46

time2：18：42：12

当timer2- timer1

我的输出应该是0:01:26



但我的输出为00:00:26。请好好纠正我的问题

Iam developing timer application, where i have created timer and want to make difference of both time in HH:MM:SS,from my side, seconds solution works perfect, but i couldn't get minutes correctly.

for example: time1: 18:41:46
time2: 18:42:12
when timer2- timer1
my output should be 0:01:26

but iam getting output as 00:00:26 . kindly rectify my problem

try
           {


               List<string> distinct = list.Distinct().ToList();

               foreach (string value in distinct)
               {

                   string svalue = value.Split(';')[1];
                   if (svalue == "SessionUnlock")
                   {
                       unlockvalue = value.Split(';')[0];
                       dt1 = DateTime.ParseExact(unlockvalue, "HH:mm:ss", new DateTimeFormatInfo());
                   }
                   else
                   {
                       lockvalue = value.Split(';')[0];
                        dt2 = DateTime.ParseExact(lockvalue, "HH:mm:ss", new DateTimeFormatInfo());
                       TimeSpan ts = dt2.Subtract(dt1);
                       MessageBox.Show(ts.ToString());
                   }


               }

Inside Distict list i have一个列表如



[0] = 18:37:20; SessionUnlock

[1] = 18:37:54; SessionLock

[2] = 18:41:46; SessionUnlock

[3] = 18:42:12; SessionLock



我尝试过：

Inside Distict list i have a list such as

[0]=18:37:20;SessionUnlock
[1]=18:37:54;SessionLock
[2]=18:41:46;SessionUnlock
[3]=18:42:12;SessionLock

What I have tried:

try
            {


                List<string> distinct = list.Distinct().ToList();

                foreach (string value in distinct)
                {

                    string svalue = value.Split(';')[1];
                    if (svalue == "SessionUnlock")
                    {
                        unlockvalue = value.Split(';')[0];
                        dt1 = DateTime.ParseExact(unlockvalue, "HH:mm:ss", new DateTimeFormatInfo());
                    }
                    else
                    {
                        lockvalue = value.Split(';')[0];
                         dt2 = DateTime.ParseExact(lockvalue, "HH:mm:ss", new DateTimeFormatInfo());
                        TimeSpan ts = dt2.Subtract(dt1);
                        MessageBox.Show(ts.ToString());
                    }
                                 
                   
                }

推荐答案

那是因为结果是26秒，不是一分钟和26秒：

That's because the result is 26 seconds, not one minute and 26 seconds:

18:42:12 - 18:41:46 == 26 seconds
18:37:54 - 18:37:20 == 34 seconds

Quote：

例如： time1：18：41：46

time2：18：42：12

当timer2- timer1

我的输出应为0:01： 26

for example: time1: 18:41:46
time2: 18:42:12
when timer2- timer1
my output should be 0:01:26

这些时间之间有26秒，输出正确。添加14秒到18:41:46到18:42:00，然后另外12到18:42:21。 14 + 12 = 26。

There are 26 seconds between those times, your output is correct. Add 14 seconds to 18:41:46 to get to 18:42:00, then another 12 gets you to 18:42:21. 14 + 12 = 26.

有时通过将其分解为简单测试更容易看到问题。这是我使用的一个：

Sometimes it is easier to see the problem by breaking it out into a simple test. Here is one that I used:

DateTime dt1 = DateTime.Now;
DateTime dt2 = dt1 + new TimeSpan(1, 23, 46);
TimeSpan ts = dt2 - dt1;

Console.WriteLine(ts); // outputs: 01:23:46

希望这有助于......

Hope this helps...
