you can get that from a socket object the RemoteEndPoint propery
returns a IPEndPoint structure you can use.

The slightly trick bit is getting the socket object, there are 2
options..

1./ The TcpClient class has a Socket property, but it is protected, so
you could create a custom class that derives from it.

2./ You can use the TcpListener.AcceptSocket method which returns a
socket. (you can create a network stream from the socket that you can
use to create BinaryReader and binaryWriter objects)

then you simply use the socket i.e.

(IpEndPoint)socket.RemoteEndPoint.Address.ToString();

Hope that Helps.

(IpEndPoint)socket.RemoteEndPoint.Address.ToString();

oops, missed a pair of brackets..

((IpEndPoint)socket.RemoteEndpoint).address.TString();

Yes and introducing a couple of new errors too

((IpEndPoint)socket.RemoteEndPoint).Address.ToString();

((IpEndPoint)socket.RemoteEndPoint).Address.ToString();

lol, that will teach me to type quick and just hit send...

I hope though that my typo's aside the point was made

Ok, i tried to create my own TcpClient class:
public class MyTcpClient: System.Net.Sockets.TcpClient
{
public MyTcpClient()
{
}

public Socket ReturnSocket()
{
return Client;
}
}

and in server.cs code i have:
MyTcpClient handler = (MyTcpClient)listener.AcceptTcpClient();
(listener is TcpListener).

It compiles, but when i start program it hangs on that line.
Why ? How can i change TcpClient to MyTcpClient so i could use
ReturnSocket() ?

Thanx again

To be honest I wouldn't be inclined to use this method, I would be more
inclined to use the 2nd method I suggested, as the first is a bit of a
hack.

The reason your code is not working is because you have introduced a
new method of the class, what you need to do is simply change the
visibility of the Socket property from protected to public in the
tcpclient class, it's a hack because although the typecast will work,
the accepttcpclient method does not return your type, it returns the
tcpclient.

thx, i used #2 method and it works fine

Is there a way to get the incoming IP using a TcpClient? or is this only available using a Socket

AFAIK you can only get the ipaddress from a socket (but just because I
don't know doesn't mean that there isn't some other way.) . However a
tcpClient does have a socket property, it is protected though and only
available to decendant classes.
