使用 C# 中提供的开始和结束时间跨度集进行时间重叠检查

Question

与C# 的时间重叠：检查 2 组开始和结束日期组合而不是圈数检查？

">

• 早上 6：00"到"下午 4：30">
">
• 上午 8：29"到"下午 4：30">

Answer 1

private static bool CheckOverlap(TimeSpan startDate1, TimeSpan endDate1, TimeSpan startDate2, TimeSpan endDate2)
{
//TODO: Make sure startDate is lower than EndDate
if (startDate2 < endDate1 && endDate2 > startDate1)
return true;
return false;
}

Answer 2

您可以创建自定义类来发送有关时间段的信息，例如：

public class TimePeriod
{
public DateTime Start { get; set; }
public DateTime End { get; set; }
public TimePeriod(DateTime start, DateTime end)
{
if( start > end)
throw new InvalidArgumentException();
Start = start;
End = end;
}
public bool Overlaps(TimePeriod tp)
{
// it's enough for one's period start or end to fall between the other's start and end to overlap
if ((Start > tp.Start && Start < tp.End ) ||
(End > tp.Start && End < tp.End) ||
(tp.Start > Start && tp.Start < End) ||
(tp.End > Start && tp.End < End) )
return true;
else
return false;
}
}

然后使用变得非常容易：

TimePeriod tp1 = new TimePeriod(dt1, dt2);
TimePeriod tp2 = new TimePeriod(dt3, dt4);
var overlaps = tp1.Overlaps(tp2);
