重载Cpomare函数

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using System.Collections;



namespace LiLe.MV.Process

{

    class ListViewItemComparer : IComparer

    {

        private int col;

        private int code;



        public ListViewItemComparer(int nCol, int nCode)

        {

            col = nCol;

            code = nCode;

        }



        public int Compare(object x, object y)

        {

            int returnVal = -1;



            if (int.TryParse(((ListViewItem)x).SubItems[col].Text, out returnVal)

                && int.TryParse(((ListViewItem)y).SubItems[col].Text, out returnVal))

            {

                returnVal = int.Parse(((ListViewItem)x).SubItems[col].Text) > int.Parse(((ListViewItem)y).SubItems[col].Text) ? 1 : -1;

            }

            else

                returnVal = String.Compare(((ListViewItem)x).SubItems[col].Text,

                    ((ListViewItem)y).SubItems[col].Text);



            returnVal *= code;



            return returnVal;

        }

    }

}

点击表头的消息传达到ColumnClick里

        private void listView_OPC_ColumnClick(object sender, ColumnClickEventArgs e)

        {

            int nSortCode = 1;



            listView_OPC.ListViewItemSorter = new ListViewItemComparer(e == null ? 0 : e.Column, nSortCode);                       



            listView_OPC.Sort();

        }
