自己都是现做现写,如果想知道最终实现的功能,请看最后

先把源码和资料链接放到这里

链接：https://pan.baidu.com/s/10MxI8-Q33-M_R2WEHqEi1A 密码：j1sz

先说一下哈,不要嫌界面不好看,自己是为了程序尽量的简单,可以通过调整颜色或者通过重绘来使使界面好看,,,,,,,,咱先学会走.....

因为咱们会用到图片所以先把图片资源加载上来,为了

调整的好看一点

现在设置,切换图片

其实呢导入图片应该先建一个资源文件更合理,后期再说

现在是让按钮状态改变了

也修改一下灯的

private void pictureBox2_Click(object sender, EventArgs e)
        {
            if (LedFlage == false)
            {
                LedFlage = true;
                pictureBox2.BackgroundImage = Properties.Resources.switchon;
                pictureBox3.BackgroundImage = Properties.Resources.ledon;
            }
            else
            {
                LedFlage = false;
                pictureBox2.BackgroundImage = Properties.Resources.switchoff;
                pictureBox3.BackgroundImage = Properties.Resources.ledoff;
            }
        }

现在做连接服务器

先说一下很多初学者会遇到的问题

这种情况是你添加了控件的事件函数,然后你又删除了,,,因为我也是经常删.................

我刚才在考虑要不要用委托和回调.....后来想了想这篇就不用了,

大家记得自己试一下这个(反正给大家说了,下次自己肯定用委托和回调写,记住不要偷懒,如果你偷懒了,后期的文章你就会无从下手,因为你连基础的都不知道)

http://www.cnblogs.com/yangfengwu/p/5761841.html

因为和android 一样只有主线程才允许操作控件,咱们就

现在做连接服务器和断开连接

先在电脑上测试
