Here is permutation private void button3_Click(object sender EventArgs e) { listBox1.Items.Add(aaa); listBox1.Items.Add(ccc); listBox1.Items.Add(bbb); char[] abc = new char[3]{'a''b''c'}; setper(abc); char[] aab = new char[3] { 'a' 'a' 'b' };// you will need all char combinations eg aacbba etc setper(aab); listBox1.Sorted = true; //label1.Text = Convert.ToString(listBox1.Items.Count); } private void swap(ref char a ref char b) { if (a == b)return; a ^= b; b ^= a; a ^= b; } public void setper(char[] list) { int x = list.Length - 1; go(list 0 x); } private void go (char[] list int k int m) { int i; if (k == m) { if (listBox1.Items.Contains(list[0].ToString() + list[1].ToString() + list[2].ToString()) == false) { listBox1.Items.Add(list[0].ToString() + list[1].ToString() + list[2].ToString()); } } else for (i = k; i { swap (ref list[k]ref list[i]); go (list k+1 m); swap (ref list[k]ref list[i]); } }

Based on the initial question the following I think is what was requested. If this is not close then we need clarification. char[] ca = { 'a' 'b' 'c' }; String Permutation; foreach (char c1 in ca) foreach (char c2 in ca) foreach (char c3 in ca) Permutation = String.Format({0} {1} {2} c1 c2 c3);

Initial you asked for 3 characters ab c. After Frogleg given the solution your query changed to something else symbols. So why not asked in first thread itself. Thats why i said your question is not clear.

Janis Peksa · Answer

I think it's very clear. What do you not understand ? I need in all combinations 'a' 'b' and 'c' to be added in listbox.

Your question is not clear explain with more details.

Any clues ?

Janis Peksa · Answer

Yes it's great but I need something else. If I will have 5 or 10 symbols ? Need somekind of generator or command to do this.

I came up with code(permutation) to do what you ask but using this listBox1.Items.Add(aaa); listBox1.Items.Add(aab); listBox1.Items.Add(aac); listBox1.Items.Add(aba); listBox1.Items.Add(abb); listBox1.Items.Add(abc); listBox1.Items.Add(aca); listBox1.Items.Add(acb); listBox1.Items.Add(acc); listBox1.Items.Add(baa); listBox1.Items.Add(bab); listBox1.Items.Add(bac); listBox1.Items.Add(bba); listBox1.Items.Add(bbb); listBox1.Items.Add(bbc); listBox1.Items.Add(bca); listBox1.Items.Add(bcb); listBox1.Items.Add(caa); listBox1.Items.Add(cab); listBox1.Items.Add(cac); listBox1.Items.Add(cba); listBox1.Items.Add(cbb); listBox1.Items.Add(cca); listBox1.Items.Add(ccc); listBox1.Sorted = true; is less code

Janis Peksa · Answer

Yes.

You mean you need a b c in all combinations ?
