C#: How to create an attribute on a method triggering an event when it is invoked?

Question

Is there a way in C# or .NET in general to create an attribute on a method which triggers an event when the method is invoked? Ideally, I would be able to run custom actions

Answer 1

You can use ContextBoundObject and IMessageSink. See http://msdn.microsoft.com/nb-no/magazine/cc301356(en-us).aspx

Be warned that this approach has a severe performance impact compared with a direct method call.
