Select from following answers:

List<string> sortedItems = new List<string>();Enumerable.Range(0, lstItems.Items.Count).ToList.ForEach(i => sortedItems.Add(lstItems.Items[i].ToString()));lstItems.Items.Clear();lstItems.Items.AddRange(sortedItems.OrderBy(o => o).ToArray());
lstItems.IsSorted = true;
lstItems.Items.Sorted = true;
lstItems.Sorted = true;
