如何将TCPListener设置为始终侦听以及当新连接丢弃当前时

我想承认我不是 c# 中最强的，我通过查看几个教程开发了这个程序，如果您能在答案中详细说明，我将不胜感激。
我希望我的TCP服务器始终侦听传入连接，当新的TCP客户端连接时，我希望它放弃旧连接并使用新连接。

我试图实现这个答案;https://stackoverflow.com/a/19387431/3540143
但我的问题是，当我模拟 TCP 客户端时，但不知何故上面的答案只会收到一条消息(我当前的代码接收发送的所有消息(，我也尝试转换数据，所以我以与以下代码相同的方式接收它，但没有任何成功。
此外，我相信上面的代码只是接受新客户端，而不会丢弃以前的连接客户端。

我当前的代码，可以处理连接并在断开连接后搜索新连接，我想做到这一点，所以我一直在寻找新连接，如果新客户端想要连接，我将丢弃电流以让新连接通过

public class TCPListener
{
    public static void Listener()
    {
        TcpListener server = null;
        try
        {
            // Set the TcpListener on carPort.
            Int32 port = 5002;
            // TcpListener server = new TcpListener(port);
            server = new TcpListener(IPAddress.Any, port);
            // Start listening for client requests.
            server.Start();
            // Buffer for reading data
            Byte[] bytes = new Byte[256];
            String data = null;
            // Enter the listening loop.
            while (true)
            {
                Console.Write("Waiting for a connection... ");
                // Perform a blocking call to accept requests.
                TcpClient client = server.AcceptTcpClient();
                Console.WriteLine("Connected!");
                // Get a stream object for reading
                NetworkStream stream = client.GetStream();
                int i;
                // Loop to receive all the data sent by the client.
                while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
                {
                    // Translate data bytes to a ASCII string.
                    data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
                    Console.WriteLine("Received: {0}", data);
                }
                // Shutdown and end connection
                Console.WriteLine("Client close");
                client.Close();
            }
        }
        catch (SocketException e)
        {
            Console.WriteLine("SocketException: {0}", e);
        }
        finally
        {
            // Stop listening for new clients.
            Console.WriteLine("Stop listening for new clients.");
            server.Stop();
        }
    }
}

编辑：如果有人需要解决我的问题，那么这就是我应用塞西里奥·帕尔多建议时代码的样子，这真的很棒！

    Form form = new Form();

            // TcpListener server = new TcpListener(port);
            server = new TcpListener(IPAddress.Any, port);
            // Start listening for client requests.
            server.Start();

            Byte[] bytes = new Byte[256];
