Events, references, garbage collecting, memory leaks and weak delegates

shake, I guess that you see that behavior with the SAVanNess sample. This was more than five years ago, and I don't remember why I included this example from Shawn A. Van Ness.

All I know is that this code is not good at all! We don't want the connections to disappear when the GC performs a collection. Especially because the observers are still alive, as you mention.

I'd say that only my example (Fabrice) is correct.

Hi,

Interesting article. I see from your example that when the observers are disconnected and garbage collection is called, the observers cleanly get unsubscribed without much fuss.

However I also have noticed that on calling GC.Collect() all the weak delegates' property wr.IsAlive becomes false even though the array list _Observers is not empty. What would be the point of that?

re: Rethrowing exceptions and preserving the full call stack trace

There was an older comment from 'Jose' about having some issues in VB.NET. I took the directly converted C# -> VB.NET code and tested it. It worked as descibed with no issues. I had code with and without the call to the Sub, and my exception log would show the proper line number with stack trace or omit it as excpected. This is a well explained entry on this topic, thank you. The VB.NET code I used is below:

Private Shared Sub PreserveStackTrace(ByVal exObj As Exception)

Dim preserveStackTrace As MethodInfo = GetType(Exception).GetMethod("InternalPreserveStackTrace", BindingFlags.Instance Or BindingFlags.NonPublic)

preserveStackTrace.Invoke(exObj, Nothing)

End Sub

VB is hiding things so much, that I don't know if it's possible. I don't see how.

Best article I read about this subject. Thanks!
