Do you mean the KeyUp event? KeyPress doesn't get fired for Arrows and the event args doesn't have a KeyCode property but for Arrow Keys in keyUp event they are:
你的意思是 KeyUp 事件？KeyPress 不会被 Arrows 触发，并且事件 args 没有 KeyCode 属性，但对于 keyUp 事件中的 Arrow Keys 它们是：
Keys.Up, Keys.Down, Keys.Left, Keys.right
Keys.Up, Keys.Down, Keys.Left, Keys.right
