events

I have seen people define their events like this:

public event EventHandler MyEvent = delegate{};

Can somebody explain how this is different from defining it without it? Is it to avoid checking for null when raising the event?

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
