C# 获取两个 datetime 对象之间的每两个小时

Question

我想获取两个日期时间对象之间每两小时的列表

以下是我每隔一小时尝试过的内容:

TimeSpan betweenTime = EndTime - StartTime; // 15:00PM - 09:00AM 
IEnumerable<int> hoursBetween = Enumerable.Range(0, (int)betweenTime.TotalHours).Select(i => StartTime.AddHours(i).Hour);   

//Output for hoursBetween
9
10
11
12  
13
14

//if between is every two hour
//the expected Output be like
9
11
13

Answer 1

你可以使用

IEnumerable<int> hoursBetween = Enumerable.Range(0, (int)Math.Ceiling(betweenTime.TotalHours / 2)).Select(i => StartTime.AddHours(i * 2).Hour);
