  • I don't understand your question. What is the `hfAllDates` exactly? You are not sorting anything, you are splitting something but that's not clear as well. – Soner Gönül Jan 22 '16 at 07:11
  • did you tried anything? – Arijit Mukherjee Jan 22 '16 at 07:11
  • is the type of date `string[]`? Then you may need to convert each element to `DateTime` first. Then you can sort it easily. – Ian Jan 22 '16 at 07:11

    This isn't quite a duplicate of [this question](http://stackoverflow.com/questions/14667754/sort-string-list-with-dates-in-c-sharp), since that one deals with lists rather than arrays. However, considering how easy it is to convert an array to a list, the answer on that question still applies. – Elezar Jan 22 '16 at 07:16

add namespace using System.Linq;

and use LINQ Query

in ascending order

  var orderedDateList = date.OrderBy(x => DateTime.Parse(x)).ToList();

in Descending oreder

var orderedDateList = date.OrderByDescending(x => DateTime.Parse(x)).ToList();

Convert date from string[] to List<DateTime> first:

List<DateTime> dtList = date.Select(x => DateTime.Parse(x)).ToList();

Then you can easily sort it:

dtList.Sort();

Using Linq's OrderBy:

var sortedDates = date.OrderBy(x => DateTime.Parse(x));

or

var sortedDates = date.OrderByDescending(x => DateTime.Parse(x));

if you are needed to sort dates descending

I suggest using Linq:

var date = hfAllDates.Value.Split('#')
  .Select(line => DateTime.Parse(x))
  .OrderBy(x => x)
  .ToList();
