推荐答案

在类级别创建一个List<Point>，并在每次单击事件时使用List.Add方法将一个新点添加到列表中. br/>
在某个时候，您将想要清除列表或复制引用并为其分配一个新列表，但这是基本的东西！

Create a List<Point> at class level, and at each click event use the List.Add method to add a new point into the list.

At some point you will want to either clear the list or copy the reference and assign a new list to it, but that''s basic stuff!
