You can define a delegate as such:

public delegate void MyHandler(object p1, object p2, object p3);

and then use it in your event definition:

public event MyHandler MyEvent;

However, this is contrary to best practices and not recommended. Instead, you should encapsulate all the extra information you require into your own EventArgs subclass and use that from your delegate:

public class MyEventArgs : EventArgs
{
    // any extra info you need can be defined as properties in this class
}

public event EventHandler MyEvent;
