How to determine whether a .NET exception is being handled?

Question

We\'re investigating a coding pattern in C# in which we\'d like to use a \"using\" clause with a special class, whose Dispose() method does different things dep

Answer 1

Not an answer to the question, but just a note that I never ended up using the "accepted" hack in real code, so it's still largely untested "in the wild". Instead we went for something like this:

DoThings(x =>
{
    x.DoSomething();
    x.DoMoreThings();
});

where

public void DoThings(Action action)
{
    bool success = false;
    try
    {
        action(new MyObject());
        Commit();
        success = true;
    }
    finally
    {
        if (!success)
            Rollback();
    }
}

The key point is that it's as compact as the "using" example in the question, and doesn't use any hacks.

Among the drawbacks is a performance penalty (completely negligible in our case), and F10 stepping into DoThings when I actually want it to just step straight to x.DoSomething(). Both very minor.
