Help with making a C# P2P Chat Program

Question

Hi everyone,

I want to make a P2P Chat client, all I want it to do is to be able to send text across to each peer.

I looked at a Chat Client from this example: http://www.geekpedia.com/tutorial239_Csharp-Chat-Part-1---Building-the-Chat-Client.html

And am wondering if it can be converted to a p2p program? If so how can it be and can someone provide some code as it will help a lot.

If it can't how can I make a really simple p2p chat program? Codes and examples will be very helpful.

btw I did look at this article, but it didn't help me: http://msdn.microsoft.com/en-us/library/ms751502.aspx

Answer 1

For P2P, you need to use UdpClient instead of TcpClient. Google should help you from here :)

Edit: Sorry, I made false assumptions in this answer. If you want to continue using TCP, that's just fine. Instead of creating a separate server application, add the server code to your client application, so that either the sender or receiver acts as the server.

I did a similar project once, only using bluetooth rather than Internet.
Mine wasn't chat so much as IM, since it only allowed for two people to converse, but we got it working by using the technique in brydgesk's edit and having the client ('talker') and server ('listener') together in the same application, in such a way that the server only puts out received messages to the local client, rather than rebroadcasting to all connections.

Hope this little bit is helpful, I don't think this is really the right place to help you write the entire application.

If it is to be done on the intranet, why not use WCF named pipes? I provide an example on my blog entitled: Create a Intra-Application Named Pipe using WCF in .Net using C#; IPC Communications.. You will need to use the non local http bindings so its not local to the machine. HTH
