How to fire an event using Dispatcher.BeginInvoke in wpf

I am get confused with the following code.

someObject
.Dispatcher
.BeginInvoke(new SomeDelegate(SomeEvent), SomeParamater);

here SomeDelegate is a delegate, SomeEvent is an event of class.

When I am running the code, SomeEvent is fired and the event handler gets the control.

Can some one explain how it is running?

The question was: how to invoke an event defined as 

public event EventHandler<SomeEventArgs> SomeEvent;

via Dispatcher.BeginInvoke?

It is done like this:

Dispatcher.BeginInvoke(new EventHandler<SomeEventArgs>(SomeEvent), this, new SomeEventArgs());

or any other value instead of this as second argument, wich gets passed to the event handler as the sender argument.
