示例
下面的代码示例创建一个窗体,该窗体包含一个 ListView 控件,该控件在单击控件中的 ListView 列时手动对项进行排序。 该示例定义一个名为 的 ListViewItemComparer
类,该类实现 System.Collections.IComparer 执行比较的 ListViewItem 接口。 该示例创建 的 ListViewItemComparer
实例,并使用它来设置 ListViewItemSorter 控件的 ListView 属性。
Sort事件处理程序中的 ColumnClick 方法调用使用 中ListViewItemComparer
定义的方法根据单击的列执行项排序。
