            if (a == x.Count)
            {
                retval.Add("");
                return retval;
            }
            foreach (Object y in x[a])
            {
                foreach (string x2 in foo(a + 1, x))
                {
                    retval.Add(y.ToString() + " " + x2.ToString());
                }

What's the problem? A recursive function is one which calls itself so put a breakpoint and figure out what is going wrong.

You are WAY off my friend. First, you don't ever get the P.ID you are looking for. Second, you are simply concatenating the contents of 3 arrays to get your output... don't make it more complicated than it has to be. Thirdly, there is no reason for a recursive function.

C#

static void Main(string[] args)
{
    List<string> userID = new List<string>() = { "1", "2","3","4"};
    List<string> unitName = new List<string>() = { "Anil", "Kumar","Phani","Shruthi"};
    List<string> pID = new List<string>() = { "0", "1" ,"1","2"};

    for(int i=0; i < pID.Count; i++)
    {
        if (pID[i] == args[0])
        {
             Console.WriteLine(userID[i] + " " + unitName[i] + " " + pID[i]);
        }
    }

Console.ReadKey();

Call your program passing the desired P.ID on the command line. You will get the output you want.
