Question

There is an array

int[] array = new int[]{6,4,10,7,7,9};

and a number 8.

I wanna sort the array around 8 by nearest number.

the nearest numbers : 9,7,7,10,6,4 respectively

because 9-1 = 8, 7+1 = 8, 7+1 = 8, 10-2 = 8, 6+2 = 8, 4+4 = 8

how can I sort this numbers.
any idea?

Answer 1

var result = array.OrderBy(i => Math.Abs(i - value))
             .ThenBy(i => i < value)
             .ToArray();
