port occupied

George George

Hello everyone,

How to check whether a port on the local machine is occupied by another thread/process? (only whether or not occupied is ok, no need to know which party occupied the port.)

Any samples or APIs to use?

thanks in advance,
George

try { Socket.Bind(EndPoint); } catch (Exception error) { }

try to bind the socket to a local end point and if it throws exception the port is used, don`t worry about opening the socket, bind does not listen yet, you have to call other functions for that ;)
