创建选定时间间隔的列表

为什么不计算 项目数 ?

int IntervalParameter = 5;

// .Range(0, 1440 / IntervalParameter) - see Zohar Peled's comment -  
// is brief, but less readable
List<string> query = Enumerable
  .Range(0, (int) (new TimeSpan(24, 0, 0).TotalMinutes / IntervalParameter))
  .Select(i => DateTime.Today
     .AddMinutes(i * (double)IntervalParameter) // AddHours is redundant
     .ToString("HH:mm"))                        // Let's provide HH:mm format 
  .ToList();

像这样?

public static IEnumerable<TimeSpan> Intervals(TimeSpan inclusiveStart, TimeSpan exclusiveEnd, TimeSpan increment)
{
    for (var time = inclusiveStart; time < exclusiveEnd; time += increment)
        yield return time;
}

示例用法:

foreach (var time in Intervals(TimeSpan.Zero, TimeSpan.FromDays(1), TimeSpan.FromMinutes(15)))
{
    Console.WriteLine(time);
}
