如何从 Linq c# 中的日期时间中删除日期

Question

i want to get only time from a datetime variable in linq query. for eaxample if i have an array of datetime having values

["02/12/1970 14:52:06","14/06/2015 12:32:44"]

then how to extract minimum time from it so that i get output like

"12:32:44" 

as if i take minimum these two it will give output "14:52:44" instead of "12:32:44" as the datepart of first value is smaller than the other.

i try this code:

time1 = table1.Min(x=>x.StartTime)

but it will give "14:52:06" as output

any suggestions?

Answer 1

First extract Time from DateTime and then get Min value

var dates = new List<DateTime>
{
    new DateTime(2020, 6, 9, 12, 35, 45),
    new DateTime(2020, 6, 10, 11, 35, 45)
};

var minTime = dates
    .Select(d => d.TimeOfDay)
    .Min();

#Update

If you want to get DateTime object that has the smallest time part, then use this:

var dateWithMinTime = dates
    .OrderBy(d => d.TimeOfDay)
    .FirstOrDefault();

Answer 2

Try

table1.Min(c => c.StartTime.TimeOfDay)

assuming StarTime is a DateTime .
