C# winform ListView实现表示点击排序

自用的小工具要实现这个功能，网上找了些代码，加工一下，以下步骤，亲测可用。菜鸟可一步步跟着来，老鸟绕道啦。

1. 新建一个排序类，代码如下：

   public 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 = -1;
            double a = 0, b = 0;

            try {
                if (double.TryParse(((ListViewItem)x).SubItems[col].Text, out a) && double.TryParse(((ListViewItem)y).SubItems[col].Text, out b)) {
                    returnVal = a >= b ? (a == b ? 0 : 1) : -1;
                    if (order == SortOrder.Descending) {
                        returnVal *= -1;
                    }
                } else {
                    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;
                    }
                }
            } catch (Exception ex) {
                //do nothing
            }
            return returnVal;

        }

 2. 确保ListView控件的属性设置如下：

3. 列点击事件设定：

        private void lv_KDHistory_ColumnClick(object sender, ColumnClickEventArgs e) {

            if (lv_KDHistory.Sorting == SortOrder.Ascending) {
                lv_KDHistory.Sorting = SortOrder.Descending;
            } else {
                lv_KDHistory.Sorting = SortOrder.Ascending;
            }

            lv_KDHistory.ListViewItemSorter = new ListViewItemComparer(e.Column, lv_KDHistory.Sorting);
            lv_KDHistory.Sort();

        }
