事件类型

示例

下面的代码示例演示了此成员的用法。 在此示例中,事件处理程序报告事件的发生情况 ItemMouseHover 。 此报告可帮助你了解事件发生的时间,并可以帮助你进行调试。 若要报告多个事件或频繁发生的事件,请考虑将 MessageBox.ShowConsole.WriteLine 消息替换为 或将消息追加到多行 TextBox

若要运行示例代码,请将其粘贴到包含名为 ListView1的类型的ListView实例的项目中。 然后,确保事件处理程序与 ItemMouseHover 事件相关联。

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) _ 
     Handles ListView1.ItemMouseHover

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Item", e.Item)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"ItemMouseHover Event")

End Sub
