using SocketAsyncEventArgs to push data to C# TCP clients

I followed link to create an Async TCP server. However, all examples cover only sending data as a response to receive. My question is how to Push data to a certain TCP client.

Let us say tat a byte[] needs to be sent/pushed to client Id 1. How can I achieve this using SocketAsyncEventArgs architecture?

I know I have to keep a list of active connections and client ids. What should this list look like in order to push data?

    public bool Send(Socket socket, byte[] message)
    {

        SocketAsyncEventArgs completeArgs = new SocketAsyncEventArgs();

        if (socket.Connected)
        {
            // Prepare arguments for send/receive operation.
            completeArgs.SetBuffer(message, 0, message.Length);
            completeArgs.UserToken = socket;
            completeArgs.AcceptSocket = socket;
            completeArgs.Completed += new EventHandler<SocketAsyncEventArgs>(OnIOCompleted);

            // Start sending asyncronally.
            socket.SendAsync(completeArgs);
        }


        return true;


    }
