A question about Exception

[tony]

Hello!!

As you know every user defined exception must be derived from class
Exception.

Now to my question if I write catch then every exception will be caught.
If I instead write catch(Exception ) then every exception will also be
caught.

These two will catch the exact same exception is this right understod?

"All exception classes should derive from the Exception base class
within the System namespace for compliance with Common Language
Specification (CLS)"

That's my source

Yes, at one time (June 2003 was the last time that article was updated,
written in August 2001) that was the recommendation. Even then, despite
the MS recommendation, it seemed dubious. Now even MS states that you gain
nothing by deriving from ApplicationExce ption. See, for example:

Best Practices for Handling Exceptions
http://msdn2.microsoft.com/en-US/library/seyhszts.aspx

"For most applications, derive custom exceptions from the Exception class.
It was originally thought that custom exceptions should derive from the
ApplicationExce ption class; however in practice this has not been found to
add significant value."
