Did you try the below mentioned solution ?

You can only send to systems that are listening for your messages. So you need a server application at the remote end, that is not blocked by a firewall.

sir, i have disable the firewall and i am using listener too but it is only listening to pc on LAN.

Richard MacCutchan 19-Feb-14 12:03pm

That makes no sense. A server just listens for messages, it makes no difference where they come from.

agent_kruger 19-Feb-14 12:06pm

point is it is not able to connect to other pc were the listener is.

Then you need to do some investigation to find out why. There is no way anyone here can guess what the problem may be.

sir in my code wen i write "serverSocket.Bind(new IPEndPoint("myIpAddress"), 8999));" it is giving error.

That is like telephoning the garage and saying "my car doesn't work".
Please do some proper debugging, and collect all the information concerning the error; we cannot guess what it may be.

can you suggest a site where i can find the code to send info. over internet in c# win. form

Try this:

serverSocket.Bind(new IPEndPoint(IPAddress.Any), 8999));

sir, i tried "my public ip" instead of this "IPAddress.Any" and it shows the same error as in parsing the public ip.

Please remove this (i.e. IP address) from your comment.Its no need here.

agent_kruger 19-Feb-14 6:08am

sir, i just did it for example but i removed it.

agent_kruger 16-May-14 9:34am

sir, does this thing work over INTERNET not INTRANET?
