(ii) 2 3 1 in ArrayList, i wan sort it in 1 2 3.

You'll need to convert each string into an array of values, sort that array, then rebuild the string.

I believe you've done all these things in previous posts, just not all together. Give it a try.

Check this example:

``````ArrayList aList = new ArrayList();

ArrayList aListNew = new ArrayList();
//you have to create a new array list, because you cannot modify the list in the loop!
foreach(string item in aList)
{
//creating a int array (generic list):
List<int> intList = item.Split(' ').ToList().ConvertAll<int>(c => Convert.ToInt32(c));
//sorting the list:
intList = intList.Select(s => Convert.ToInt32(s)).OrderBy(o => o).ToList();
StringBuilder sb = new StringBuilder();
for (int j = 0; j < intList.Count; j++)
{
if ((j + 1) < intList.Count)
sb.Append(intList[j].ToString() + " ");
else
sb.Append(intList[j].ToString());
}
}``````

thanks. i get it.
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
my ArrayList is shown below:
1 2
1
2
1 2
2
1
2 3
2
3
1 2 3
1 2
3
1 3
1
3
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
1:4
3:4

hope anyone can help me correct my code..

``````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<string, double> sortList2 = new SortedList<string, double>();
string text = "";

foreach (string key in arryKey)
{
if (sortList.ContainsKey(key))
{
if (!sortList2.ContainsKey(key))
{
