A simple scenario: a custom class that raises an event. I wish to consume this event inside a form and react to it.
How do I do that?
Note that the form and custom class are separate classes.
public class EventThrower
{
public delegate void EventHandler(object sender, EventArgs args) ;
public event EventHandler ThrowEvent = delegate{};
public void SomethingHappened() => ThrowEvent(this, new EventArgs());
}
public class EventSubscriber
{
private EventThrower _Thrower;
public EventSubscriber()
{
_Thrower = new EventThrower();
// using lambda expression..could use method like other answers on here
_Thrower.ThrowEvent += (sender, args) => { DoSomething(); };
}
private void DoSomething()
{
// Handle event.....
}
}
