As Brannon says, it's OrderByDescending and ThenByDescending:
var query = from person in people
orderby person.Name descending, person.Age descending
select person.Name;
is equivalent to:
var query = people.OrderByDescending(person => person.Name)
.ThenByDescending(person => person.Age)
.Select(person => person.Name);
Use System.Linq.Enumerable.OrderByDescending()?
For example:
var items = someEnumerable.OrderByDescending();
Try this:
List<int> list = new List<int>();
list.Add(1);
list.Add(5);
list.Add(4);
list.Add(3);
list.Add(2);
foreach (var item in list.OrderByDescending(x => x))
{
Console.WriteLine(item);
}
This only works in situations where you have a numeric field, but you can put a minus sign in front of the field name like so:
reportingNameGroups = reportingNameGroups.OrderBy(x=> - x.GroupNodeId);
However this works a little bit different than OrderByDescending when you have are running it on an int? or double? or decimal? fields.
What will happen is on OrderByDescending the nulls will be at the end, vs with this method the nulls will be at the beginning. Which is useful if you want to shuffle nulls around without splitting data into pieces and splicing it later.
LastOrDefault() is usually not working but with the Tolist() it will work. There is no need to use OrderByDescending use Tolist() like this.
GroupBy(p => p.Nws_ID).ToList().LastOrDefault();
Try this another way:
var qry = Employees
.OrderByDescending (s => s.EmpFName)
.ThenBy (s => s.Address)
.Select (s => s.EmpCode);
