Ch 3: Inheritance

So far just one question.

Do most developers define protected virtual events or do they define protected virtual On{eventName} methods to be overridden in a derived class?

In other words, do you prefer this:

public delegate void PlanetDestroyedEventDelegate(object sender, EventArgs e);
public class HG2TG {

    public virtual event PlanetDestroyedEventDelegate PlanetDestroyed;

    public void DestroyPlanet() {
        // zap
        EventArgs e = new EventArgs();
        PlanetDestroyed(this, e);
    }
}

or this:

public delegate void PlanetDestroyedEventDelegate(object sender, EventArgs e);
public class HG2TG {

    public event PlanetDestroyedEventDelegate PlanetDestroyed;

    public void DestroyPlanet() {
        // zap
        this.OnDestroyPlanet();
    }

    protected virtual void OnDestroyPlanet() {
        EventArgs e = new EventArgs();
        PlanetDestroyed(this, e);
    }
}

Pros? Cons?
