Linq Order by a specific number first then show all rest in order
If i have a list of numbers:
1,2,3,4,5,6,7,8
and I want to order by a specific number and then show the rest. For example if i pick '3' the list should be:
3,1,2,4,5,6,7,8
Looking for linq and c#. Thank you
You can use a comparison in OrderBy or ThenBy to perform a conditional sorting.
list.OrderByDescending(i => i == 3).ThenBy(i => i);
I use OrderByDescending because i want matching results first(true is "higher" than false).
Maybe something like this:
List<int> ls=new List<int>{1,2,3,4,5,6,7,8};
int nbr=3;
var result= ls.OrderBy (l =>(l==nbr?int.MinValue:l));
