You can try this code. Just one more thing Math.Sign reuturns 0 as well so if you have 0 in your array make sure to include that at required place. int [] arr = { 4 -5 6 8 -2 3 -7 9 }; var res = arr.OrderByDescending(x => Math.Sign(x));

Hello Nakhia Shrama Try This..i hope this will help you.. using System.Linq; private int [] GetSortedArray( int [] Arr) { List int > NegArr = Arr.ToList().Where(x => x x).ToList(); // Negative Number List in Ascending Order List int > AllArr = Arr.ToList().Where(x => x > 0).ToList().OrderBy(x => x).ToList(); // Positive Number List in Ascending Order AllArr.AddRange(NegArr); return AllArr.ToArray(); }
