如何以时间格式显示十进制值 [英] how to show decimal value in time format

问题描述

我有工作时间的员工。喜欢

小时1 = 8.0

小时2 = 10.5



现在要获得小时数，我首先乘以小时用60手然后用分针加总。

sum =（总和+（hh * 60）+ mm）;



现在总时数除以60

sum = Math.Round（sum / 60,2）;



，结果是

sum = 18.83



现在我想显示18.83像18.5





请给我任何解决方案。





谢谢。

解决方案

你应该使用 TimeSpan s。

这样：

< pre lang =c＃> TimeSpan ts1 = TimeSpan.FromHours（ 8 ）;
TimeSpan ts2 = TimeSpan.FromHours（ 10 。 5 ）;
TimeSpan total = ts1 + ts2;
MessageBox.Show（total.TotalHours.ToString（））;

如何使用DateTime类？

Hi,
i have working hours of employee. Like
hours1=8.0
hours2=10.5

Now to get sum of hours,i first multiply hours hand with 60 and then sum it with minutes hand.
sum = (sum + (hh * 60) + mm);

Now to get total hours divided sum by 60
sum = Math.Round(sum / 60, 2);

and the result is
sum=18.83

Now i want to display 18.83 like 18.5


Please give me any solution if any will have.


Thanks.

解决方案

You should use TimeSpans.
This way:

TimeSpan ts1 = TimeSpan.FromHours(8);
TimeSpan ts2 = TimeSpan.FromHours(10.5);
TimeSpan total = ts1 + ts2;
MessageBox.Show(total.TotalHours.ToString());

How about using the DateTime class instead?

It has all the methods that you want...
