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,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;
      }
    }
  }
