在C#中,可以使用ListView的ListViewItemSorter属性对ListView进行排序
- 首先,创建一个自定义的比较器类,继承自
IComparer
接口:
using System.Collections; public class ListViewItemComparer : IComparer { private int _column; private SortOrder _sortOrder; public ListViewItemComparer(int column, SortOrder sortOrder) { _column = column; _sortOrder = sortOrder; } public int Compare(object x, object y) { ListViewItem itemX = (ListViewItem)x; ListViewItem itemY = (ListViewItem)y; int result = string.Compare(itemX.SubItems[_column].Text, itemY.SubItems[_column].Text); if (_sortOrder == SortOrder.Descending) return -result; else return result; } }
- 在你的表单上添加一个ListView控件,并为其添加列。同时,需要处理ListView的
ColumnClick
事件,以便在用户点击列标题时对数据进行排序。
using System; using System.Windows.Forms; public partial class MyForm : Form { private int _sortColumn = -1; public MyForm() { InitializeComponent(); listView1.Columns.Add("Name", 100); listView1.Columns.Add("Age", 50); listView1.ColumnClick += ListView1_ColumnClick; } private void ListView1_ColumnClick(object sender, ColumnClickEventArgs e) { SortOrder sortOrder = SortOrder.Ascending; if (_sortColumn == e.Column) { if (listView1.Sorting == SortOrder.Ascending) sortOrder = SortOrder.Descending; else sortOrder = SortOrder.Ascending; } listView1.Sorting = sortOrder; listView1.ListViewItemSorter = new ListViewItemComparer(e.Column, sortOrder); listView1.Sort(); _sortColumn = e.Column; } }
现在,当用户点击ListView的列标题时,将根据所选列对数据进行升序或降序排序。
