如果您不知道如何进行工作，建议您与客户联系并退还他们.

您可以处理要在其上绘制的窗体的绘画事件.您可以处理控件的事件，并以此为基础.我不知道定向线"是什么意思，但是您可以画任何喜欢的东西.其余的，如鼠标事件，您需要自己编写.我将亲自为线条创建一个类，并收集它们的一个集合，以便我的paint事件可以重复绘制，而我的鼠标事件可以重复进行响应.

I suggest you contact your client and refund them if you have no idea how to do the work.

You handle the paint event of your form to draw onto it. You can handle the event of a control, and draw on that. I have no idea what you mean by ''directed line'', but you can draw anything you like. The rest, like mouse events, you''ll need to write yourself. I''d personally create a class for lines, and have a collection of them that my paint event could iterate over to draw, and my mouse events could iterate over to respond to.
