I am new to c# and I am building server / client application.
I have created both the server and the client successfully , but when any client connects to the server... I need to save that client because the server is supposed to send them a message after 10 minutes .

```
private void Form1_Load(object sender, EventArgs e) {
    TcpListener myList;

    myList = new TcpListener(IPAddress.Any, 8001);

    while (true)

    {
        TcpClient client = myList.AcceptTcpClient();

        MessageBox.Show("Connection accepted from " + client.Client.LocalEndPoint.ToString());
    }
}

```

Now , my problem is how to save "client" id or anything about this client which is connected, to send message after 10 minutes from server to this client.

Can anyone help please?
