Better to Ref. whole exception handling in C# rather than just focus catch block . e.g. http://www.tutorialsteacher.com/csharp/csharp-exception-handling

Use of return statements are not restricted in a catch block. Use of return is logical. However, a simple principle to follow is, when I write a method with return type is “it should either return an expected value OR it must throw an exception” . With this approach, you can always avoid the NullpointerExceptions. But, if you are catching an exception, and you don’t want it to bubble up - then a return can be written in the catch block or outside of it. If you are returning something to notify an error, I recommend to use exceptions and not return values. Because exceptions are available for that purpose.
