我想同时处理click和doubleclick事件但是我只能得到显示的Click事件消息。

Answer 1

这是因为您在单次点击

也就是说，您在单击（带有{{1} ），系统将无法识别双击。超过了它认为下次点击（在对话框显示时按住）的时间。分开双击序列。

相反，请使用MessageBox并在output window中查看结果

Debug.WriteLine

Jakob Busk Sørensen的精彩评论

这也意味着您可以单击使用的功能受到限制如果您还想使用双击。基本上任何东西单击运行，也将双击运行。或者考虑根据您要执行的操作单击右键。

Answer 2

如果您要同时处理Click和Double-Click并执行不同的操作，或者要防止一次激活两次相同的操作，则可以延迟{{1}中的代码的执行}处理程序，基于SystemInformation.DoubleClickTime值（可由用户根据偏好设置）。

然后，在尚未执行Click动作的情况下，在Click处理程序中执行一个动作。

Double-Click
