how to combine the latest key and the previous key value

Sin Yee

hi....after i finish my combination, i need to combine back my values to the lastest key.
For example:
my previous data set
1 2 :3
1 2 3 :4
1 2 3 4 :1
2 3 :2
3 4 :1
......
after i doing the intersection(using the key),i need got the new keys.
2 1
2 1 3
2 1 3 4
2 3
3 4

Now, i need to take back the previous values from the previous data set and combine with the lastest key
the expected result that i want is like this:
2 1 :3
2 1 3 :4
2 1 3 4 :1
2 3 :2
3 4 :1

the values is come from previous data without changing anything.
how i combine this two so that can show this result?

Trying adding the following to the end of your previous code:

   string[] myArray3 = new string[myArray2.Count];

   et.Reset(); // reset itemS enumerator to just before first key/value pair

   for(int i = 0; i < myArray3.Length; i++)
   {
   et.MoveNext();
   myArray3[i] = String.Format("{0}:{1}", myArray2[i], et.Value.ToString());
   }

   string message2 = String.Join("\r\n", myArray3);
   ItemKey.AppendText(message2);

thanks for helping...really thanks .....

here is my coding
HashSeths1 = new HashSet();

   var g = from k in sItem.Keys
   orderby sItem[k] descending
   select k;

   foreach (var k in g)
   {
   //display3 += k + ":" + sItem[k] + "\r\n";
   SingleSupport.AppendText(k + ":" + sItem[k] + "\r\n");
   hs1.Add(k);
   }

   //key for comabination
   List myArray1 = new List();

   IDictionaryEnumerator et = itemS.GetEnumerator();
   while (et.MoveNext())
   {
   KeyitemS.AppendText(et.Key.ToString() + ":" + et.Value.ToString() + "\r\n");
   myArray1.Add(et.Key.ToString());
   }

   HashSet hs2 = new HashSet(hs1);
   HashSet hs3 = new HashSet();

   List storehs2 = new List();

   for (int i = 0; i < myArray1.Count; i++)
   {
   foreach (string t in myArray1[i].ToString().Split(' '))
   {
   hs3.Add(t);
   }

   var clone = new HashSet(hs2);

   hs2.IntersectWith(hs3);

   foreach (string f in hs2)
   {
   storehs2.Add(f);
   }

   hs2 = clone;
   hs3.Clear();
   }
   string[] strarry = storehs2.ToArray();

   string[] myArray2 = new string[myArray1.Count];
   int[] lens = new int[myArray1.Count];
   int index = 0;

   foreach (string y in myArray1)
   {
   lens[index] = y.Replace(" ", "").Length;
   index++;
   }
   index = 0;
   int index2 = 0;

   string[] temp = new string[lens[0]];
   foreach (string q in strarry)
   {
   if (index2 < lens[index])
   {
   temp[index2] = q;
   index2++;
   }
   else
   {
   myArray2[index] = String.Join(" ", temp);
   index++;
   temp = new string[lens[index]];
   temp[0] = q;
   index2 = 1;
   }
   }
   myArray2[index] = String.Join(" ", temp);

   string message = String.Join("\r\n", myArray2);
   ItemKey.AppendText(message);


i need to take the key (myArray2) to combine with the "et.value.toString()" to generate that result i want...but i don't know how to do it...
