sockets - C# TCP Client listening for data

Question

I would like to connect to a specific barcode reader at my work but currently I'm facing some problems to understand how TCP stream reading works with C#.

I've looked for many code samples on stackoverflow and as I can see, people oftenly open a connection, send a command and then ask for the reply.

The point is, the barcode reader just accept a TCP connection and then send the data with my data.

I would like find the most efficient way to use TcpClient or NetworkStream to read in a continuous way the data. I mean, I would like to listen for the data when it's incoming but also process many other things at the same time I'm listening.

I was wonderning if simple TCP libraries exists like a one with a Connect function, and an event firing when you receive data (with a delimiter or with a length).

Thanks

TCP doesn't sound right, but if it is it might be acting as a http server.If it is then you'd use a HttpClient. If it is just TCP, you would do something like:Async Client Socket
