implement a class Position containing:
-A static method public static ArrayList identifyPosition (int val,int [] tab) that returns an ArrayList containing all the positions of the value val of the array tab.
example: if tab is {2,0,-1,2,3,5,4,2,5} and val=2 then the method returns the ArrayList {0,3,7} that are the index of the value 2 in the array tab.

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 < tab.Length; i++)
{
if (tab[i] == val) al.Add(i);
}

return al;
}
}

class Test
{
static void Main()
{
int[] tab = {2,0,-1,2,3,5,4,2,5};
ArrayList al = Position.identifyPosition(2, tab);
foreach(int i in al) Console.Write("{0} ", i);
Console.ReadKey();
}
}
