c# socket白名单问题

Question

c# socket 服务端设置白名单，拒绝访问，如何实时告知客户端，以及端口占用问题

  TCP    192.168.0.156:5000     0.0.0.0:0              LISTENING       85028
  TCP    192.168.0.156:5000     192.168.0.156:52654    FIN_WAIT_2      85028
  TCP    192.168.0.156:52654    192.168.0.156:5000     CLOSE_WAIT      81072

以下是服务端，请问如何处理客户端，或者服务端应该如何优化

Socket clientSocket = tcpListener.AcceptSocket();
if (whitelist.Contains(clientSocket.RemoteEndPoint.ToString().Split(':')[0]))
{
    ParameterizedThreadStart parameterizedThreadStart = new ParameterizedThreadStart(ReceiveData);//创建一个obj传参的线程委托
    Thread receiveMsgThread = new Thread(parameterizedThreadStart);//创建一个线程
    receiveMsgThread.IsBackground = true;//设置线程为后台线程
    receiveMsgThread.Start(clientSocket);//启动线程并且传入参数clientSocket套接字


    dicClientSockets.Add(clientSocket.RemoteEndPoint.ToString(), clientSocket);//将套接字加入集合
    dicReceiveMsg.Add(clientSocket.RemoteEndPoint.ToString(), receiveMsgThread);//将信息接收线程加入集合
    Form_Server._AddListEvent(clientSocket.RemoteEndPoint.ToString());
}
else 
{
    clientSocket.Close();
}
