Identify IDisposable objects

Question

i have to review a code made by some other person that has some memory leaks. Right now i'm searching the disposable objects to enclause them with the using statement and i would like to know if there is a quick way that tells you all the disposable objects declared in. I mean something like resharper or another visual studio plugin.

thanks.

Answer 1

I know what you mean. I don't know, but look at FxCop. It might have a rule in there somewhere that checks whether objects implementing IDisposable are not disposed. Just a hunch, mind.

UPDATE: Mitch Wheat writes:

FxCop includes the rule, thats says all types that derive from types that implement IDisposable should implement the Dispose() pattern

Thanks, Mitch.

Answer 2

You could do this with ReSharper. With ReSharper you can navigate implementations of any interface with ease by using Alt-End, but for a popular interface such as IDisposable this is not practical.

Here's what you could do:

1. Go to Object Browser (Ctrl-Alt-J or View->Object Browser)
2. Find System.IDisposable
3. Right click and select "Find Usages Advanced" (ReSharper's menu item)
4. User Find, check "Implementations", under Scope choose Solution
5. You will get a list of all types (of your solution) implementing IDisposable. Those in bold are the ones you want - they implement IDisposable directly.

Hope that helps.
