socket关闭时需要关闭的东西，停止服务，停止监听，停止socket

1.线程需要关闭

Thread TempThread;   
//开启接收线程   
TempThread = new Thread(new ThreadStart(this.StartReceive));   
TempThread.IsBackground = true;//设置为后台线程   
TempThread.Start();   
  
TempThread.Abort();//关闭线程  

2.监听需要关闭

TcpListener lisner;   
//创建网络监听   
lisner = new TcpListener(ipep);   
lisner.Start();   
  
lisner.Stop();  

3.Socket需要关闭

Socket client = lisner.AcceptSocket();   
  
//关闭套接字   
client.Close();
