如何从列表中找到最低和最高时间？

Question

I have a string list holding time values in this format: 11:25:46.123 , I would like to be able to find highest and lowest time value from this list. How can I do it?

I tried something like this, but I am not sure if it is correct and I don't know what to do next.

List<TimeSpan> time = StringList.Select(x => TimeSpan.ParseExact(x, "HH:mm:ss.fff", null)).ToList();

EDIT: I am getting error:

Input string was not in a correct format.

Answer 1

I am getting error: Input string was not in a correct format.

Your timespan format is not correct. Try this

var StringList = new[] { "21:25:46.123" };
List<TimeSpan> time = StringList
                      .Select(x => TimeSpan.ParseExact(x, @"hh\:mm\:ss\.fff", null))
                      .ToList();
var max = time.Max();
var min = time.Min();

Answer 2

Have you tried:

TimeSpan maxTimeSpan = time.Max();
TimeSpan minTimeSpan = time.Min();

Answer 3

Try this

TimeSpan _maxtime= time.Max(); // For max time
TimeSpan _mintime= time.Min();// For min time

also take a look at MSDN

Answer 4

Try without using ParseExact

List<TimeSpan> times = StringList
    .Select(x => TimeSpan.Parse(x))
    .OrderBy(ts => ts)
    .ToList();
TimeSpan shortest = times.First();
TimeSpan longest = times.Last();
