grubiai tariant delegatas leidzia metoda naudoti kaip reiksme, t.y. perduoti 
per parameterus i kita metoda, grazinti (return) is metodo ir t.t. delegatai 
yra type-safe, t.y. jie turi atitikti signatura metodo i kuri jie 
reprezentuos.
Eventai yra tiesiog palengvinimas programuotojui, compileris tai pavercia 
combine/remove delegate operacijas.
pvz is Jeffrey Richter "CLR via C#" knygos

public event EventHandler<NewMailEventArgs> NewMail;

When the C# compiler compiles the line above, it translates this single line 
of source code
into the following three constructs:


// 1. A PRIVATE delegate field that is initialized to null
private EventHandler<NewMailEventArgs> NewMail = null;
// 2. A PUBLIC add_Xxx method (where Xxx is the Event name)
// Allows methods to register interest in the event.
public void add_NewMail(EventHandler<NewMailEventArgs> value) {
// The loop and the call to CompareExchange is all just a fancy way
// of adding a delegate to the event in a thread-safe way
EventHandler<NewMailEventArgs>prevHandler;
EventHandler<NewMailEventArgs> newMail = this.NewMail;
do {
prevHandler = newMail;
EventHandler<NewMailEventArgs>newHandler =
(EventHandler<NewMailEventArgs>) Delegate.Combine(prevHandler, value);
newMail = Interlocked.CompareExchange<EventHandler<NewMailEventArgs>>(
ref this.NewMail, newHandler, prevHandler);
} while (newMail != prevHandler);
}
// 3. A PUBLIC remove_Xxx method (where Xxx is the Event name)
// Allows methods to unregister interest in the event.
public void remove_NewMail(EventHandler<NewMailEventArgs> value) {
// The loop and the call to CompareExchange is all just a fancy way
// of removing a delegate from the event in a thread-safe way
EventHandler<NewMailEventArgs> prevHandler;
EventHandler<NewMailEventArgs> newMail = this.NewMail;
do {
prevHandler = newMail;
EventHandler<NewMailEventArgs> newHandler =
(EventHandler<NewMailEventArgs>) Delegate.Remove(prevHandler, value);
newMail = Interlocked.CompareExchange<EventHandler<NewMailEventArgs>>(
ref this.NewMail, newHandler, prevHandler);
} while (newMail != prevHandler);
}
