C# Code Checker

[Paul Jones]

Does anyone know if there is a C# code checker that will spot any (or
preferably all) of the following:
- Unused parameters in functions;
- Unused functions;
- Wrong scope (of functions, variables, enums, etc.,) e.g. can their scope
be reduced from public to protected or private.

Thanks, Paul

FXCop may well do all of those - I can't say I use it myself.

ReSharper (jetbrains.com) is excellent at spotting this kind of thing
within the IDE, but I don't know whether you can tell it to perform the
check outside the IDE and produce a report, for instance.

ReSharper, as John recommended, does all of those things well. Unfortunately
I had to stop using it because of a few silly things, like it made my
context menu ridiculously long.

Paul,

I've been tempted to develop something along those lines - even something
for my own use. There are many opportunities here such as the one you've
mentioned, plus others such as (for example) passing OK, Cancel, Retry to a
MessageBox on the Smartphone - that parameter is always invalid, and
changing method to private in a post-op, and notifying you of recursion
especially in "public int Age { get { this.Age; } }".

I use FxCop regularly and it does help, I wish they would update it
occasionally though - FxCop was release 6/2006.

FxCop with "a grain of salt", please. If you run it against the Microsoft
Enterprise Library you'll get a list of errors that will keep you busy for
days...

Peter,

I make sure to only enable the rules I care about. Do you know if MSFT
plans on updating FxCop? Do you know of any better tools out there worth
trying?

Thanks,

Hilton

If you want serious code analysis get a copy of NDepend. It has a code query
language (CQL) that if the stuff you're looking for isn't already defined
you can use to create a query that will extract whatever information you
like.
