dpmain 主界面开启心跳调用Socket 处理接受消息类

private void timer1_Tick(object sender, EventArgs e) { //客户端调用服务器 if (AlertingSignal.Alarmessage == 0) { PublicClass.ClientConnection.ClientPractice(); thread = new Thread(new ThreadStart(PublicClass.ClientConnection.ClientAccept)); thread.Start();//启动线程 } else { return; } }

写一个控制台应用程序（服务器）  模拟 装置发来的短消息
