Difference in invoking through Delegates and Events C#

Question

What is the difference?

Using Delegate

public delegate void TestDelegate();
public TestDelegate delObj = SomeMethod;

public void S

It works exactly same. If you use

public event EventHandler SomeEvent;

the C# compiler does (simplified code):

private EventHandler SomeEventField;
public void add_SomeEvent( EventHandler handler) {
    this.SomeEventField = (EventHandler)Delegate.Combine(this.SomeEvent, handler);
}
public void remove_SomeEvent( EventHandler ) {
   this.SomeEventField = (EventHandler)Delegate.Remove(this.SomeEvent, handler);
}

The method add_SomeEvent is called when you use SomeEvent += ... and the remove_SomeEvent is called when you use SomeEvent -= ....

However in both cases there are used same delegates.
