Communication between two programs on same computer – How?

Question

I don't know how to begin. After Googling, I've found this here :

//This is how you do it (kudos to sipwiz)
UdpClient udpServer = new UdpClient(localpt); 

//This is what the proprietary (see question) sender would do (nothing special) 
//!!! The following 3 lines is what the poster needs...
//(and the definition of localpt, of course)
UdpClient udpServer2 = new UdpClient();
udpServer2.Client.SetSocketOption(
    SocketOptionLevel.Socket,
    SocketOptionName.ReuseAddress, true);

udpServer2.Client.Bind(localpt);

But I don't know what else I need. I tried an example from here , but got an error message: "An existing connection was forcibly closed by the remote host."

How do I proceed?

Answer 1

I'd suggest ditching UDP. Instead, use Named Pipes .

They are more reliable.

Answer 2

我认为最好将WCF与命名管道绑定一起使用

Answer 3

Named pipe is the best option on the same system. Due the fact that the performance is better then TCP cause the traffic is not using the network interfaces.
