Checking for Objects that implement IDisposable but aren't properly disposed

Question

Is there a way to automatically check existing C# source code for instances of objects that are not properly disposed of ie. using try / catch / finally or using statements? Or do I need to just manually look at the code?

Answer 1

Take a look at FxCop for VS2010 - I believe they restored the DisposeObjectsBeforeLeavingScope rule - which may do exactly what you want.

Answer 2

• Use FX Cop for a rule to check if IDisposable are placed in a proper Using block...

• You can use reflector to go through the object with IDisposable

Answer 3

CodeRush has some support for spotting obvious variants of this. Another possible option is (perhaps via an optional compilation symbol) add a finalizer to your own IDisposable objects, and complain loudly if they get finalized without being disposed (set a bool flag in the Dispose). But note: having a finalizer changes the behaviour of the objects, so don't leave it in production code (or even your regular unit tests).
