I'd like the aspect to exit a method invocation based on a condition like the following:

    [AttributeUsage(AttributeTargets.Method)]
    public class IgnoreIfInactiveAttribute : OnMethodBoundaryAspect
    {
        public override void OnEntry(MethodExecutionEventArgs eventArgs)
        {
             if (condition)
            {
                **// How can I make the method return here?**
            }
        }
    }

Any help much appreciated.
