我如何返回时间跨度值? [英] how can i return time span value?

问题描述

如何将总时间返回为时间跨度类型?
还是我的solutin就在这里?
如果您认为此代码有误，请告诉我?

请看一下这段代码，尝试解决我的问题.
活动是一个列表，并且timelenght等于endtime-starttime
我想在这里将所有timeleght都添加为总时间，但我不知道如何返回总时间?

请帮我吗?

但在任何地方谢谢你

how can i return totaltime as a timespan type''s?
or my solutin is right here?
and if you think this code have a mistake tell me ?

look at this code please and try to solve my problem .
activity is a list and timelenght equals endtime - starttime
i want to adding all of timeleght''s here as totaltime and i dont know how can i return totaltime?

plaease help me?

but anywhere thank you

public TimeSpan calculateTotaltime()

    {
        foreach (Activity a in myData.activities)
        {
                a.totaltime += a.timelenght;


        }
        return   ?       ;

   }

请帮忙

推荐答案

DateTime then = DateTime.Now;
Thread.Sleep(1000);
TimeSpan span = DateTime.Now - then;

我不知道您到底是什么Activity类型，所以我不知道timelength的类型.根据您的单位，可以创建System.TimeSpan的实例.例如，使用静态方法System.TimeSpan.FromMilliseconds.

还有FromTicks，FromSeconds，FromMinutes等方法.
请参阅 http://msdn.microsoft.com/en-us/library/system.timespan.aspx [^ ] .

I don''t know exactly what Activity type do you mean, so I don''t know the type of the timelength. Depending on the units of you can create an instance of System.TimeSpan. For example, use static method System.TimeSpan.FromMilliseconds.

There are also the methods FromTicks, FromSeconds, FromMinutes, etc.
See http://msdn.microsoft.com/en-us/library/system.timespan.aspx[^].

如果我正确理解了您的问题，您需要做的是将所有活动的持续时间加起来，以得出如下总数:

If I understood your question correctly, what you need to do is sum all of activities'' durations to get the total like this:

public TimeSpan calculateTotaltime()
{
    TimeSpan total = TimeSpan.Zero;
    foreach (Activity a in myData.activities)
        total += a.timelength;

    return total;
}

total是列表中所有活动的持续时间之和.

Here total is the sum of the durations of all the activities in your list.
