推荐答案

ContextMenuStrip有自己独立的事件：你可以将Expand项目Click事件发送到一个处理程序，将Collapse发送到另一个处理程序，或者你可以将它们发送到同一个处理程序并使用 sender 参数来决定点击哪个 - 它始终是控件（或表单或类依赖），它首先表示事件。

Each item in the ContextMenuStrip has it's own separate events: you could either send the "Expand" item Click event to one handler, and the "Collapse" even to a different handler, or you could send them both to the same handler and use the sender parameter to decide which was clicked - it is always the control (or form, or class depending) that signaled the event in the first place.
