Is there any valid reason to ever ignore a caught exception

Question

Wow, I just got back a huge project in C# from outsourced developers and while going through my code review my analysis tool revealed bunches of what it considered bad stuff

Answer 1

Unless your catch code will either

1. Log the exception
2. Repackage the exception into another exception that matches the same abstraction. and throw again
3. Handles the exception the way you see suitable

You can ignore the exception, but at least mention the expected exception in the method docs, so the consumer can expect and handle if necessary
