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

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.

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#3.2WhyDelega...

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.

-HTH
