想在列表中找到重复时间跨度的重复项 [英] Want to find duplicates in list which have overlaps timespans

问题描述

public class  MyRows
{
    public string StartStop { get; set; }
    public string EndStop { get; set; }
    public TimeSpan StartTime { get; set; }
    public TimeSpan EndTime { get; set; }
    public string Day { get; set; }
}

List<MyRows> lmr = new List<MyRows>();
lmr.Add(new MyRows { StartStop = "a", EndStop = "b", StartTime = new TimeSpan(09, 00, 00), EndTime = new TimeSpan(11, 00, 00),Day=DayOfWeek.Sunday.ToString() });
lmr.Add(new MyRows { StartStop = "a", EndStop = "b", StartTime = new TimeSpan(09, 00, 00), EndTime = new TimeSpan(11, 00, 00), Day = DayOfWeek.Sunday.ToString() });
lmr.Add(new MyRows { StartStop = "a", EndStop = "b", StartTime = new TimeSpan(10, 00, 00), EndTime = new TimeSpan(12, 00, 00), Day = DayOfWeek.Tuesday.ToString() });
lmr.Add(new MyRows { StartStop = "a", EndStop = "b", StartTime = new TimeSpan(10, 30, 00), EndTime = new TimeSpan(12, 00, 00), Day = DayOfWeek.Sunday.ToString() });
lmr.Add(new MyRows { StartStop = "a", EndStop = "b", StartTime = new TimeSpan(09, 00, 00), EndTime = new TimeSpan(13, 00, 00), Day = DayOfWeek.Tuesday.ToString() });
lmr.Add(new MyRows { StartStop = "a", EndStop = "b", StartTime = new TimeSpan(09, 00, 00), EndTime = new TimeSpan(11, 00, 00), Day = DayOfWeek.Thursday.ToString() });
lmr.Add(new MyRows { StartStop = "a", EndStop = "b", StartTime = new TimeSpan(11, 00, 00), EndTime = new TimeSpan(12, 00, 00), Day = DayOfWeek.Thursday.ToString() });

我想根据StartStop，EndStop，StartTime，EndTime(相同的TimeSpans)和DayOfWeek查找重复项

I want to find duplicates on the basis of StartStop, EndStop, StartTime, EndTime (same TimeSpans) and DayOfWeek

例如，在上面的列表中

• 第一个对象与第二个和第四个对象重复(第四个bcoz 时间跨度重叠)
• 由于时间跨度重叠，第三对象与第五对象重复.
• 第六个对象与第七个对象没有重复，因为时间跨度不重叠，但日期相同.

• first object is duplicate with second and forth object (forth bcoz timespan overlapping)
• third object is duplicated with fifth object because of timespan overlapping.
• sixth object is not duplicated with seventh beacuse timespan are not overlapping but day is same.

推荐答案

在这里，您不会感到复杂，

Here you go without complication,

   var result = lmr.Where(i => lmr.Any(o => YourCondition(i,o) && i != o));

    //up to you
    private bool YourCondition(MyRow i, MyRow o)
    {
        return i.StartTime >= o.StartTime && i.EndTime <= o.EndTime && i.Day == o.Day;
    }
