How to split the line by line

hi..i am doing split now. But i face some problem.

For example'
i got data in String array
"1 2"
"1 2 3"
"2 3"
.......
But, after i split the data
All will become like this
1
2
1
2
3
2

but this is not i want..
the expected output that i want is like this
Output 1

2
output2
1
2
3
output3
2
3
and so on......this is my coding. hope someone can help me to solve this problem

List> P = new List>(itemS.ToList());

KeyitemS.Clear();

String[] SplitA;

String[] SplitB;

List l = new List();

foreach (KeyValuePair pair in P)

{

KeyitemS.AppendText(pair.Key + ":" + pair.Value + "\r\n");

l.Add(pair.Key);

}

String ink ="";

List U =new List();

foreach (String inter in l)

{

// MessageBox.Show(inter);

SplitA = inter.Split(' ');

SplitB = new String[SplitA.Length];

for (int i = 0; i < SplitA.Length; i++)

{

SplitB[i] = SplitA[i];

U.Add(SplitB[i]);

}

HashSet hset1 = new HashSet(v);

HashSet hset2 = new HashSet(U);

hset1.IntersectWith(hset2);

foreach (string inter1 in hset1)

{

ink += inter1;

}

MessageBox.Show(ink);

I will not say this a good logic, just for understanding or wait for more replies..

            string[] s1 = { "1 2" };
   string[] s2 = { "1 2 3" };
   string[] s3 = { "2 3" };
   List s = new List();
   s.Add(s1);
   s.Add(s2);
   s.Add(s3);

   for (int i = 0; i < s.Count; i++)
   {
   Console.WriteLine("Output " + (i + 1));
   foreach (string item in s[i][0].ToString().Split(' '))
   {
   Console.WriteLine(item.Trim());
   }
   }
   Console.ReadLine();
