need help to sort number

sorry, cant use list. This because after that , next step i need to use the sortlist8.value to do some calculation. the problem above i solved.
Now i meet another problem.
that is i need to use the value from sortlist8 to do calculation .

My total transaction is 5.
for example-> 1 2:3
therefore, i need to use the value divide by total transaction.
the formula is : sortlist8.Value/ total transaction
here is my coding.

Dictionary sortList8 = new Dictionary();
  string sigh = "";
  foreach (string ry in ang)
  {
  if (sortList2.ContainsKey(ry))
  {
  if (!sortList8.ContainsKey(ry))
  {sortList8.Add(ry, sortList[ry]);

  }
  sigh += String.Format("{0}:{1}\r\n", ry, sortList8[ry]) ;
  }
  }
 
  richTextBox12.Clear();
  richTextBox12.AppendText(sigh);

  string b = txtTotalItems.Text;
  double e = Double.Parse(b);
  double a;

  richTextBox9.Clear();
  foreach (double wee in sortList8.Values)
  {

  a = (wee / e);
  richTextBox9.AppendText(a.ToString() + "\n");
}

now my problem is i just can show some only, there are:
0.6
0.6
0.6
0.4

Actually, my expected output is :
0.6
0.6
0.6
0.6
0.4
0.6
0.6
0.4


May i know any error with my coding?

As I said earlier, you can't use a Dictionary for sortList8 which doesn't support duplicate keys. Instead you've got to use an ordinary list.

Here's your data and code modelled as a console app:

i have another problem.
 my arrayList are shown below:
1 2
1 3
1 2
2 3
1 2 3
1 3
2 3
1 2 3


my another sortedeList are shown below:
(1):  4
(2):  4
(1 2):  3
(3):  4
(1 3):  3
(2 3):  3
(1 2 3):  2

Now my problem is i want to compare arrayList with sortedList . if the key are same, then will show value.
my expected output is :
1 2:3
1 3:3
1 2:3
2 3:3
1 2 3:2
1 3:3
2 3:3
1 2 3:2

 my code are below:
Dictionary sortList8 = new Dictionary();
            string sigh = "";
            foreach (string ry in ang)
            {
                if (sortList2.ContainsKey(ry))
                {
                    if (!sortList8.ContainsKey(ry))
                    {
                        sortList8.Add(ry, sortList[ry]);
                        sigh += String.Format("{0}:{1}\r\n", ry, sortList8[ry]);
                    }
                }
            }
        
        richTextBox12.Clear();
   richTextBox12.AppendText(sigh);

hope someone can help me..thx..

Even though you've sorted the ArrayList, you won't be able to get the order you want using that code because sortList2 will impose its own sort order on the keys and will place 1:4 before 1 2:3 for example. Also I see now that you're including duplicates.

To maintain the correct order, replace sortList2 with an ordinary List:

            List list2 = new List();
            string text = "";


            foreach (string key in arryKey)
            {
                if (sortList.ContainsKey(key))
                {
                      string temp =  String.Format("{0}:{1}", key, sortList[key])
                      list2.Add(temp);
                      text += String.Format("{0}\r\n", temp);
                }
            }

            richTextBox5.Clear();
            richTextBox5.AppendText(text);

thanks . ur coding is very helpful.
now if i take the arrayList that already sort to compare with my another sortedLIst.
my sortedLIst is show below:
(1):  4
(2):  4
(1 2):  3
(3):  4
(1 3):  3
(2 3):  3
(1 2 3):  2

 i wan the output is like this:
1 2:3
1:4
2:4
1 2:3
2:4
1:4
2 3:3
2:4
3:4
1 2 3:2
1 2:3
3:4
1 3:3


may i know how to correct the code below?
            richTextBox6.Clear();
            ArrayList arryKey = new ArrayList(richTextBox4.Lines);
            for (int i = 0; i < arryKey.Count; i++)
            {
                string temp = (string)arryKey[i];
                string[] numbers = temp.Trim().Split(' ');
                Array.Sort(numbers);
                arryKey[i] = String.Join(" ", numbers);
                richTextBox6.AppendText(arryKey[i].ToString()+"\n");
            }
 
            SortedList sortList2 = new SortedList();
            string text = "";

            foreach (string key in arryKey)
            {
                if (sortList.ContainsKey(key))
                {
                    if (!sortList2.ContainsKey(key))
                    {
                        sortList2.Add(key, sortList[key]);
                        text += String.Format("{0}:{1}\r\n", key, sortList2[key]);
                    }
                }
            }
           richTextBox5.Clear();
            richTextBox5.AppendText(text);
