Try the following: using System; using System.Collections; class Position { public static ArrayList identifyPosition (int val int[] tab) { ArrayList al = new ArrayList(); for(int i = 0; i { if (tab[i] == val) al.Add(i); } return al; } } class Test { static void Main() { int[] tab = {20-1235425}; ArrayList al = Position.identifyPosition(2 tab); foreach(int i in al) Console.Write({0}  i); Console.ReadKey(); } }
