C# ListView 点击表头对数据进行排序功能的实现代码

private void listView1_ColumnClick(object sender, ColumnClickEventArgs e)    {      if (listView1.Columns[e.Column].Tag == null)      {        listView1.Columns[e.Column].Tag = true;      }      bool tabK = (bool)listView1.Columns[e.Column].Tag;      if (tabK)      {        listView1.Columns[e.Column].Tag = false;      }      else      {        listView1.Columns[e.Column].Tag = true;      }      listView1.ListViewItemSorter = new ListViewSort(e.Column, listView1.Columns[e.Column].Tag);      //指定排序器并传送列索引与升序降序关键字      listView1.Sort();//对列表进行自定义排序}

public class ListViewSort : IComparer  {    private int col;    private bool descK;    public ListViewSort()    {      col = 0;    }    public ListViewSort(int column, object Desc)    {      descK = (bool)Desc;      col = column; //当前列,0,1,2...,参数由ListView控件的ColumnClick事件传递    }    public int Compare(object x, object y)    {      int tempInt = String.Compare(((ListViewItem)x).SubItems[col].Text, ((ListViewItem)y).SubItems[col].Text);      if (descK)      {        return -tempInt;      }      else      {        return tempInt;      }    }  }
