Delegate

[Jimmy]

Hi

Can someone tell me what the advantage of a delegate is? Maybe an example
code would help

Thanks

Hi,

A delegate allow you to call a different method each time, or choose at
runtime what method to call, as long as a method has the same signature that
the delegate you can use it.
Cheers,

For event handlers, or whenever you want a function pointer, basically.

You could think of it as a "one method interface" if you want, but you
don't need to explicitly implement it, or you can pseudo-implement it
several times in the same class (just by giving several different
methods the same signature as the delegate). You can also build
delegate instances from static methods.
