SortedList Desc Order

Question

I am using SortedList to arrange arraylist records dynamically in sort order by datecolumn, but by default it is sorting in ascending

Answer 1

You can just use Reverse() to sort the SortedList in descending order:

var list = new SortedList();

list.Add(new DateTime(2000, 1, 2), "Third");
list.Add(new DateTime(2001, 1, 1), "Second");
list.Add(new DateTime(2010, 1, 1), "FIRST!");
list.Add(new DateTime(2000, 1, 1), "Last...");

var desc = list.Reverse();

foreach (var item in desc)
{
    Console.WriteLine(item);
}
