C # Capture Console (console) Shutdown event

Sometimes the console (console) application that is developed internally by the company runs on the server and automatically shuts down because it encounters certain exceptions, which requires a mechanism to capture the console shutdown event and write the log for ease of maintenance and debugging.

The source code is as follows:
