How can I clear event subscriptions in C#?

Question

Take the following C# class:

c1 {
 event EventHandler someEvent;
}

If there are a lot of subscriptions to c1\'s someEven

Answer 1

class c1
{
    event EventHandler someEvent;
    ResetSubscriptions() => someEvent = delegate { };
}

It is better to use delegate { } than null to avoid the null ref exception.
