c# class instance communication

Question

When you have different instances of the same class such as 'FootballTeam' for example and you want to let another instance of this FootballTeam class know that something occured, whats the best way to go about this?

Events won't really work I guess...

EG:

FootballTeam A = new FootballTeam();
FootballTeam B = new FootballTeam();

// now A needs to let B know about it's manager change
// manager is a property inside this class...

Answer 1

Events could work:

FootballTeam A = new FootballTeam();
FootballTeam B = new FootballTeam();
A.ManagerChanged += B.OnOtherManagerChanged;

Definition of the event -- FootballTeam calls its OnManagerChanged method when its Manager property changes value:

class FootballTeam
{
    public event EventHandler ManagerChanged;

    protected virtual void OnManagerChanged(EventArgs e)
    {
        EventHandler handler = ManagerChanged;
        if (handler != null)
            handler(this, e);
    }

    public void OnOtherManagerChanged(object sender, EventArgs e)
    {
        FootballTeam otherTeam = (FootballTeam) sender;
        // A manager changed on a different FootballTeam instance
        //  ...do something here
    }
}
