问题描述

您好，我是这个网站上的新手，我尝试学习C＃。

我有一个关于四色问题的问题。我需要做一个以win形式模拟四个颜色贴图的应用程序。我知道如何使用回溯在控制台应用程序中做，但我尝试使用相同的算法以win形式做但我不知道如何绘制。

anyoane可以帮我提供如何实现这个或完整应用程序源代码的源代码吗？

谢谢！

Hello, i'm new on this site and i try to learn C#.
I have a question about the four color problem. I need to do an aplication that simulate the four color maps in win forms. I know how to do in console application using backtracking, but i tried to do in win form using the same algorithm but i don't know how to draw.
Can anyoane help me with source code of how i can implement this or with source code of the entirely application ?

推荐答案

不，这是你的作业，你应该自己做，不要标记我们做什么！ ：笑：



使用Winforms绘图很简单：只需处理Form或Panel的Paint事件，并使用提供的Graphics上下文。

例如，这将绘制一个与红色圆圈重叠的绿色矩形：

No, this is your homework, and you are expected to do it yourself, not get marked on what we do! :laugh:

Drawing in Winforms is easy: just handle the Paint event for a Form or Panel, and use the supplied Graphics context.
For example, this will draw a Green Rectangle overlapping a Red Circle:

private void myPanel_Paint(object sender, PaintEventArgs e)
    {
    Graphics g = e.Graphics;
    g.FillEllipse(Brushes.Red, 100, 100, 200, 200);
    g.FillRectangle(Brushes.Green, 150, 150, 50, 50);
    }

所以试试吧，试验一下，看看会发生什么！

So try it, experiment, and see what happens!
