Sam Hobbs · Answer

Note that you did not define what you mean by middle. If you need the middle numerically and the array is not sorted then you need to sort it first as in Array.Sort(ia);. Also you can get the middle using ia[ia.Length >> 1].

As you haven't specified that the numbers should be ordered I'm assuming you just want the middle number in the sequence: using System; class Program { static void Main() { int[] ia = {1 12 34 56 22}; Console.WriteLine(The middle number is {0} GetMiddleNumber(ia)); // 34 Console.ReadKey(); } static int GetMiddleNumber(int[] ia) { // if length is odd return middle numer if (ia.Length % 2 == 1) return ia[ia.Length/2]; // if length is even return the first of the two middle numbers return ia[ia.Length/2 - 1]; } }
