问题
Title covers it all. I'd like classes which implement IDisposable to show up in a specific color so I can know if I should wrap them in a using block. Is there a setting or a process by which you can extend the IDE?
回答1:
It is certainly possible to do this though it isn't as simple as just changing a setting. You would need to write a Visual Studio addin to accomplish this.

I assume this will become easier/extension-free once Roslyn comes out, but this is presently not easy because you can't access the code as C# from an extension easily.
In Resharper it's easy, though! My example was tested in ReSharper 9.0. Sadly, there's no easy way to give this to you.
- Resharper -> Options -> Code Inspection -> Custom Patterns -> Add, dialog popsup
- Select C# (upper left)
- Select "Find" (upper right)
- Add the pattern of
new $disp$($args$) - Pattern severity: Show as suggestion
- Description: Disposable construction
- "Add Placeholder" of type: Type, name:
disp, type: System.IDisposable - "Add Placeholder" of type: Arguments, name:
args
Save and you'll now get a "suggestion" whenever a new disposable is being constructed.
Adding the pattern $disp$ $var$ = $exp$; could also be helpful. All things equal with exp is defined as an expression.

You cannot. This would require language service support and neither C# or VB.Net provide this functionality.
Cannot is probably too strong of a word. It's certainly possible to do this with an Add-In which does deep inspection of the code and figures out hierarchies. However it's a very non-trivial task.
回答4:
Sure, there is a large set of tools to build VS extensions, see Visual Studio 2008 SDK 1.1 But time required to build such an add-in will require more time that you will spend by browsing components and determining whether they are Disposable or not
回答5:
I am not sure, if FXCop or StyleCop can do this already. But then, it will be a post-compile suggestion/warning.
Resharper suggests this, I guess.
回答6:
The word on the street is this kind of thing will be much easier in VS.NET 2010. The editor is being rewritten in WPF.
回答7:
Maybe I'm a bad person for doing this, but I've been using this piece of code recently:
public static void BulkDispose(object[] objects)
{
foreach (object o in objects)
{
if (o != null)
{
if (o is IDisposable)
{
IDisposable disposable = o as IDisposable;
disposable.Dispose();
}
}
}
}
