When use a delegate?

When would you choose to use a delegate rather than calling a function
directly? What's the advantages? Thanks...

Re: When use a delegate?

One prime example is events.

Another is when you have to run more than one "function" when a specific
action happens.

Another is when you have a library that has to make a callback to the
calling application, but you do not know what the event name is at the time
you create the library.

Re: When use a delegate?

Sometimes you don't know what function you're going to want to call, only
its signature. Delegates allow you that flexibility.

Here is a link to a good article that presents an introduction to
delegates - to the extent that delegates are relevant to events.

http://www.codeproject.com/KB/cs/event_fundamentals.aspx#3.2 WhyDelegates4

While the article is about events, one must have a good understanding of
delegates in order to really understand events in C#. So much of the article
addresses delegates.
