✅ Pipe client server

Hey! I've been reading into the C# Pipe stream stuff, because I need some interprocess communication. What I want is 2 processes being able to send a bit of data to each other whenever. All the example's I've seen so far just - Open a stream - Send some data - Recieve some data back - Close the stream Can somebody point me in the right direction on how to do more long lived communication? If I want to support recieving and sending at the same time, do I need multiple Streams per program?

Or, do I connect a new Client and server everytime I want to send something?

in the end they work more or less like any other stream once the connection is established. so u can have async tasks that simply read the next packet on the event and raise some kind of event ur application can react to and completely unrelated to that u can also simply send packets

So, they Read and Write operations don't interfere? For example if the server writes a buffer and then the client writes a buffer they are separate?

C# Channels Explained (System.Threading.Channels)
In this c# channels tutorial I answer the questions: what is a channel? how does a channel work? how to use a channel? when to use a channel? what problem does a channel solve? Contents: 1. Basic problem that would require shared state to improve.
2. Simple custom implementation of channels. 3. Real World Example of Channels in ASP.NET Core ...

it covers System.Threading.Channels, which I think it what you want

Yeah indeed between processes Ah great, that makes more sense So, then I'm gonna run a thread that listens for incoming data and calls events based on that Is it safe to (while that thread is running) also write to the same stream?

🎉 Thanks! Will close when I get the implementation down Seems this is incorrect I only just now started implementing two way messaging But you cannot actually send and receive at the same time Since internally the stream uses the same handle for sending and receiving If you are sending data, calling any functions to receive data will result in a broken stream exception I'm probably gonna use 2 different pipe streams to mitigate this

hey, i looked at some old code that was used, they did indeed use 2 streams under the hood. sorry for the misinformation 😒
