计算可配置时间之间的分钟数

Question

我有一个 Journey object，它有一个 DateTime JourneyStartTime { get; set; } 和一个 DateTime JourneyEndTime { get; set; }。我想计算晚上 10 点到早上 6 点之间的旅程总分钟数（注意这超过了午夜）。

我已经尝试使用 TimeSpans 来指示晚上 10 点和早上 6 点，但我不确定这是否是最好的数据类型。

此逻辑的域是基于保险的。 X 公司想要对在 X - Y 小时内开车的司机进行评分。这些时间应该是可配置的。这是一个场景：

A journey takes place on the same day between 5pm and 6pm. Company X Inurance is interested in journeys between 10pm and 6am. How many minutes did that journey spend in the time period that Company X is interested in?

上面的答案是：0，但我的代码给了 60 分钟（这里是 dotnetFiddle）。

这是代码。

代码

using System;

public class Program
{
    public static void Main()
    {
        var shortSameDayJourney = new Journey {
            JourneyId = 1,
            // start of journey - 5pm - start
            JourneyStartTime = new DateTime(2018, 12, 17, 17, 00, 00, DateTimeKind.Utc),
            // end of journey - 6pm - end
            JourneyEndTime = new DateTime(2018, 12, 17, 18, 00, 00, DateTimeKind.Utc)
        };

        var scoreTimePeriod = new InsurerTimePeriodScoreSetting {
            // start of insurer's time period.
            StartOfTimePeriod = DateTime.Now + TimeSpan.FromHours(22),
            // end of insurer's time period.
            EndOfTimePeriod = DateTime.Now + TimeSpan.FromHours(30)     
        };

        var minutesInTimePeriod = getNumberOfMinutesThatJourneyWasInTimePeriod(shortSameDayJourney, scoreTimePeriod);
        Console.WriteLine("Number of minutes the journey was within the time period the insurer had sepcified:");       
        Console.WriteLine(minutesInTimePeriod + " minutes");
    }

    public static double getNumberOfMinutesThatJourneyWasInTimePeriod(
        Journey journey,
        InsurerTimePeriodScoreSetting insurerTimePeriod) {

        var JourneyStart = journey.JourneyStartTime;
        var JourneyEnd = journey.JourneyEndTime;

        var timeSpan = insurerTimePeriod.EndOfTimePeriod - insurerTimePeriod.StartOfTimePeriod;
        var startDif = (JourneyStart - insurerTimePeriod.StartOfTimePeriod);
        var endDif =  (insurerTimePeriod.EndOfTimePeriod - JourneyEnd);

        var time = timeSpan - startDif - endDif;

        return time.TotalMinutes;
    }
}

public class Journey {
    public int JourneyId {get;set;}
    // journey start date and time in UTC, comes form a tracking device on vehicle.
    public DateTime JourneyStartTime {get;set;}
    // journey end date and time in UTC, comes form a tracking device on vehicle.
    public DateTime JourneyEndTime {get;set;}
}

public class InsurerTimePeriodScoreSetting {
    public DateTime StartOfTimePeriod {get;set;}
    public DateTime EndOfTimePeriod {get;set;}
}

Answer 1

Timespan 只给出 2 DateTime's 之间的原始时间所以我不得不更改你的 Journey 初始化，这样我就可以在同一天进行比较

   var shortSameDayJourney = new Journey
   {
       JourneyId = 1,
       // start of journey - 5pm - start
       JourneyStartTime = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 17, 00, 00, DateTimeKind.Utc),
       // end of journey - 6pm - end
       JourneyEndTime = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 18, 00, 00, DateTimeKind.Utc)
    };

InsurerTimePeriodScoreSetting

相同

 var scoreTimePeriod = new InsurerTimePeriodScoreSetting
 {
     // start of insurer's time period. 18/12 22:00
      StartOfTimePeriod = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 22, 0, 0, DateTimeKind.Utc),   // DateTime.Now + TimeSpan.FromHours(22),
     // end of insurer's time period. 19/12 6:00
     EndOfTimePeriod = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day + 1, 6, 0, 0, DateTimeKind.Utc)  // DateTime.Now + TimeSpan.FromHours(30)
 };

现在您需要做的只是一个简单的检查 - 旅程时间是否在 InsurerTimePeriodScoreSetting

之间

if (JourneyStart >= insurerTimePeriod.StartOfTimePeriod && JourneyEnd <= insurerTimePeriod.EndOfTimePeriod)
{
// your same calculation here
}
else
   return 0;
