C# ListView中点击表头ColumnClick实现对相应列的排序

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
}

//排序类的定义:
///
///自定义ListView控件排序函数
///
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;
}
}
}
