若要运行示例代码, 请将其粘贴到包含名为ListView ListView1的类型的实例的项目中。To run the example code, paste it into a project that contains an instance of type ListView named ListView1. 然后, 确保事件处理程序与ItemMouseHover事件相关联。Then ensure that the event handler is associated with the ItemMouseHover event.

private void ListView1_ItemMouseHover(Object sender, ListViewItemMouseHoverEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Item", e.Item );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "ItemMouseHover Event" );
}
Private Sub ListView1_ItemMouseHover(sender as Object, e as ListViewItemMouseHoverEventArgs) _
