Hi all,

can anyone told me that Kind of sort is it below:

C#

string[] data = listbox1.Items.Cast<string>().ToArray();

          ArrayList arr = new ArrayList();

          foreach (string s in data)
              if (!s.StartsWith(" "))
                   arr.Add(s);

          arr.Sort();
          listBox2.DataSource = arr;

Sounds like homework?

Solution 2

As mentioned in the solution 1, Sort method of the System.Array class of mscorblib.dll used QuickSort internally as showing below,

C#

IL_0128:  call   instance void System.Array/SorterGenericArray::QuickSort(int32,
                                                                                int32)

Hope it helps :)

Solution 1

If you are asking what kind of sort is used by ArrayList.Sort, it uses Quicksort.
See the Remarks section in this link: http://msdn.microsoft.com/en-us/library/8k6e334t.aspx[^]
