Multi client, one server (Sending objects)

TCP/IP

Okay. I've tried to ask this question before but don't think I've worded it correctly. I currently have a TCP server that can accept an unlimited amount of clients and send bytes of data (string). I now want to send custom objects using a method such as Serialization. How do I write a server that will work with my client side code (below) and accept multiple connections? I also need the server to send the object to all other clients once an object has been received so I will need to keep the connection open on client side.

Here is the code I've got for the Serialization process:

Client side:

Person p = new Person("Tyler", "Durden", 30); // create my serializable object
string serverIp = "127.0.0.1";

TcpClient client = new TcpClient(serverIp, 9050); // have my connection established with a Tcp Server

IFormatter formatter = new BinaryFormatter(); // the formatter that will serialize my object on my stream

NetworkStream strm = client.GetStream(); // the stream
formatter.Serialize(strm, p); // the serialization process

strm.Close();
client.Close();

Server side:

TcpListener server = new TcpListener(9050);
server.Start();
Console.WriteLine("Server ready");
TcpClient client = server.AcceptTcpClient();
NetworkStream strm = client.GetStream();
IFormatter formatter = new BinaryFormatter();
Person p = (Person)formatter.Deserialize(strm); // you have to cast the deserialized object
Console.WriteLine("Hi, I'm " + p.FirstName);

strm.Close();
client.Close();

So what I need to know is how do I make the code above, accept multiple connections, keep them open and then send any received objects to all connected clients. Any help would be appreciated.
