Send a socket between applications c#

Question

I would like to know if there is a way where you have a .net app name appA where it receives a tcp socket connection and then according to some rules will send the socket connec

Answer 1

Proxy

One option is to make AppA a proxy. That is, it accepts the connections, and connects on behalf the client to AppB - and merely forwards the data.

Socket Duplication

The solution you are really looking for is Socket.DuplicateAndClose() (make sure you read the documentation carefully). This allows you transfer the control of a socket between processes.

Typically you would:

• Start AppA, AppB and AppC.
• Use remoting to allow AppA to communicate with AppB and AppC.
• When a connection is made to AppA, determine who to send it to and:
  • Duplicate and close the socket in AppA.
  • Send the socket to the child process via remoting.
  • Open the socket in AppB using the Socket(SocketInformation) constructor.
