another sockets question

[Jeremy Martin]

This is an example that I found.


public static void Main()
{

try
{
// Set the TcpListener on port 23.
Int32 port = 23;
IPAddress localAddr = IPAddress.Parse("127.0.0.1");

// TcpListener server = new TcpListener(port);
TcpListener server = new TcpListener(localAddr, 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.
// You could also user server.AcceptSocket() here.
TcpClient client = server.AcceptTcpClient();
Console.WriteLine("Connected!");

data = null;

// Get a stream object for reading and writing
NetworkStream stream = client.GetStream();

Int32 i;

// Loop to receive all the data sent by the client.
while((i = stream.Read(bytes, 0, bytes.Length))!=0)
{


My question is does anyone know how to modify it so that I can listen on a port for more than one connection.

Thanks.

I'm not too keen on network programming, but wont it listen for all connections to that port?

[Jeremy Martin]

I would think so but if you telnet in to this example more than once, it will only return data to the first connection.

I'm new to network programming, but I'm working on an app of my own. I am using asynchronous client/server socket connections and once a new connection is created, I spin off a new class to handle the client and then go back to listen on the port for a new connection.

Here's an example from MSDN on asynchronous sockets (nonblocking):
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconusingnon-blockingclientsocket.asp
and that's where I got started with my program, hope that helps out.

I have spent the past week trying to find out a way to implement an easy way to send data using ftp in my applications, and so far without luck. I did it quite easily in Visual Basic, but then I used Winsock controls that had events for everything... Just code and it worked...

With C# it is much harder I think. But when I read the MSDN article on asynchronous sockets, I realized that I could use the delegetes pretty much the same way as vb uses events for it's controls.

When using ftp, I need 2 sockets, one that listens to a port and one that sends data to port 21. I also need them to operate in two threads due to their asynchronous nature... and that's precicely what async. sockets is all about!!!!!

Now comes the real question... how do I really start? In the MSDN article, the methods where nice and all.. but I wish there where some kind of full example... not just the methods.... :(
