Answer 1

就是照搬的MSDN里面，首先是添加列的值： for (int ii = 0; ii < listView2.Items.Count; ii++)
                        {
                            listView2.Items[ii].SubItems.Add(File.GetCreationTime(listView2.Items[ii].Text).ToString());
                        }。
再来就是MSDN的了。
 private int sortColumn = -1; this.listView2.ColumnClick += new System.Windows.Forms.ColumnClickEventHandler(this.listView2_ColumnClick);private void listView2_ColumnClick(object sender, ColumnClickEventArgs e)
        {
            // Determine whether the column is the same as the last column clicked.
            if (e.Column != sortColumn)
            {
                // Set the sort column to the new column.
                sortColumn = e.Column;
                // Set the sort order to ascending by default.
                listView1.Sorting = SortOrder.Ascending;
            }
            else
            {
                // Determine what the last sort order was and change it.
                if (listView1.Sorting == SortOrder.Ascending)
                    listView1.Sorting = SortOrder.Descending;
                else
                    listView1.Sorting = SortOrder.Ascending;
            }
            // Call the sort method to manually sort.
            listView1.Sort();
            // Set the ListViewItemSorter property to a new ListViewItemComparer
            // object.
            this.listView1.ListViewItemSorter = new ListViewItemComparer(e.Column,
                                                              listView1.Sorting);
        }        class ListViewItemComparer : IComparer
        {
            private int col;
            private SortOrder order;
            public ListViewItemComparer()
            {
                col = 0;
                order = SortOrder.Ascending;
            }
            public ListViewItemComparer(int column, SortOrder order)
            {
                col = column;
                this.order = order;
            }
            public int Compare(object x, object y)
            {
                int returnVal;
                // Determine whether the type being compared is a date type.
                //try
                //{
                    // Parse the two objects passed as a parameter as a DateTime.
                    System.DateTime firstDate =
                            DateTime.Parse(((ListViewItem)x).SubItems[col].Text);
                    System.DateTime secondDate =
                            DateTime.Parse(((ListViewItem)y).SubItems[col].Text);
                    // Compare the two dates.
                    returnVal = DateTime.Compare(firstDate, secondDate);
                //}
                // If neither compared object has a valid date format, compare
                // as a string.
                //catch
                //{
                    // Compare the two items as a string.
                    returnVal = String.Compare(((ListViewItem)x).SubItems[col].Text,
                                ((ListViewItem)y).SubItems[col].Text);
                //}
                // Determine whether the sort order is descending.
                if (order == SortOrder.Descending)
                    // Invert the value returned by String.Compare.
                    returnVal *= -1;
                return returnVal;
            }
        }

可能是因为你单击的列的元素不是DateTime的格式的文本.
我看你的代码中,好像只有SubItem是DateTime格式的文本,而Item.Text可能就不是了.如果你点的是这一列可能就出错了.
