It is still unclear to me why we would use events when delegates seem to do
just fine. People say that events make it so the publisher doesn't need to
know about the listeners. What does that mean? Why are events better than
delegates? Thanks

Hello!
I am still transitioning from VB.NET to C#. I undertand the basic concepts
of Delegates, more so of Events and somewhat understand AsyncCallback
methods. But I need some clarification on when to use one over another? If
anyone could provide any additional info, your comments, best practices, any
good articles, specific examples, etc.
Thank you

Hi,
what is the difference between using events and delegates (apart from the
syntax) ?
have a look at following (working) programs please
(you can just copy/paste and build it) :
First program uses delegates, the second events but both do inherently the
same :

There are a set of clients who need to be notified of certain events. I have
used events and delegates (publisher-Subscriber model) for the
notification mechanism. All the clients register with the event publisher
and subscribe for the events that they are interested in. When a certain
event happens, the subscribers are notified about it.
I want the clients to return a value after their callback method is called.
If any of the client...

Hi,
I am new to C# (with long year experience in C++) and I am a bit confused by
the language construct of events. What is it I can do with events that I
cannot do with delegates? At the moment it seems to me that Microsoft has
developed similar functionality via two keywords. I do understand that an
event offers better encapsulation as the underlying delegate is private, but
is that all ?

Hi,
I currently work in a project written fully in C# where we make
extensive use of delegates and events. We have a model where a "state",
an object holding data but not much code but which fires events when
the data changes, is often the central part. Connected to these states
are various observers that act on changes in data, by altering the
information presented to the user, executing code and so on, each
observer with its own...

I understand delegates (static and non-static) and I agree they are
very useful, and that the "Forms" used in the Windows .NET API could
not work without them. That said, I'm curious as to how many heavy
duty pro programmers in this newsgroup have actually used a delegate
in their code, say in the last year of coding. By "use" I mean
constructed a delegate and using it in an Event Source class and an
Event Receiver class.

I'm studying the book "Microsoft Visual Basic.NET Language Reference" and I
would like some clarify the difference between events and delegates. On page
156 I see a WinForms example of timer that uses the "WithEvents" and events.
There is another example on page 124 that shows how to use delegates to sort
an array.
I don't understand the difference between events and delegates. Are they
redundant features? How do I decide which to use?

I've read every example i could find on the subject and still couldn't
figure out its proper usage.
What's the point of delegates, why can't I just invoke the method
directly???
Can someone please help?

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
