Bind and Listen on an Available Port in a Range
See more Socket/SSL/TLS Examples
Demonstrates Socket.BindAndListenPortRange, which searches an inclusive port range for an available TCP port, binds it, and begins listening. It returns the selected port, or -1 on failure.
Background. This is useful when any of several ports is acceptable and the application needs to discover which one was bound.
