hi try.... int[] a = new int[10] { 10 20 30 40 50 60 70 80 90 100 }; int count = (a.Length / 2) - 1; int swapDataIndex = 0; for (var arrayData = 0; arrayData { int dummyNo = a[swapDataIndex + 1]; a[swapDataIndex + 1] = a[swapDataIndex]; a[swapDataIndex] = dummyNo; swapDataIndex += 2; } foreach (var datainArray in a) { Console.WriteLine(datainArray); } hope this will help you.

You can also do this using LINQ: int[] a = new int[10] { 10 20 30 40 50 60 70 80 90 100 }; a = a.SelectMany((i n) => { if(n % 2 == 1) return new int[]{i a[n-1]}; else return new int[0]; }).ToArray(); foreach (var i in a) { Console.Write({0}  i); } The output is: 20 10 40 30 60 50 80 70 100 90

if there are 20 elements in an array and we want to swap 1st element to 2nd 3rd element with 4th 5th with 6 and so on....... means if array is 1[0] index number 2[1] 3 4 5 6 7 8 9 10[9] after swapping the element will be 2[0]index 1 4 3 6 5 8 7 10 9[9]index
