C# Randomize ListView Items

Hi I am using the following to randomize a ListView in C#.

I am wondering if there is a more efficient way to do this as it currently takes 6 seconds per 5000 items.

Looking for working example that would be better than mine.

    lvTitles.BeginUpdate();
    ListView.ListViewItemCollection list = lvTitles.Items;
    Random rng = new Random();
    int n = list.Count;
    while (n > 1)
    {
        n--;
        int k = rng.Next(n + 1);
        ListViewItem value1 = (ListViewItem)list[k];
        ListViewItem value2 = (ListViewItem)list[n];
        list[k] = new ListViewItem();
        list[n] = new ListViewItem();
        list[k] = value2;
        list[n] = value1;
    }
    lvTitles.EndUpdate();
