Close a Socket Connection

Demonstrates Socket.Close, which gracefully terminates and closes the current TCP, TLS, or SSH channel connection. The argument bounds how long to wait for clean shutdown processing.

Background. A value of 0 waits indefinitely for the clean close, while a positive value waits up to that many milliseconds.
