时间跨度日怎么可能只持续 8 小时？

Question

我以分钟为单位保存了一个持续时间，并希望输出“1 天 5 小时 30 分钟”。目前我将分钟添加到时间跨度并执行以下操作：

TimeSpan ts = new TimeSpan(0,0,1800, 0);
Response.Write(ts.Days + "day(s) " + ts.Hours + " hour(s)" + ts.Minutes + " minutes");

但现在我只对一天的工作时间感兴趣。因此，当 TimeSpan 的持续时间为 27 小时时，它不应创建输出“1 天 3 小时”。我想要“3天3小时”。

是否有一种简单的方法可以使用 Timespan 对象来做到这一点？是否可以更改 TimeSpan 的默认行为？还是我必须编写自己的自定义时间跨度类？

谢谢 cpt.oneeye

Answer 1

你能简单地使用吗：

(int)(ts.TotalHours / 8)

而不是ts.Days?然后使用

(((int)ts.TotalHours) % 8)

而不是ts.Hours。

Answer 2

你需要实现这样的东西：

TimeSpan workday = new TimeSpan(8, 0, 0);
int workdays = ts.Ticks / workday.Ticks
TimeSpan rest = new TimeSpan(ts.Ticks % workday.Ticks)
Response.Write(workdays  + "workday(s) and" + rest.ToString());

会写一些类似的东西

"3 workday(s) and 3:32"

这是我的代码，供需要的人使用。

DynamicTimeSpan 类：

using System;
using System.Text;

    /// Optimal for calculating bussinesshours.

        }

        public DynamicTimeSpan(int totalMinutes)
