object.RemoveDelegateFromEvent(eventname, delegate)

Delegates are automatically removed from all events when they are released if the reference count of the delegate goes to zero.

Examples

button_OnClick = new DotNetDelegate(sys, "System.EventHandler",  ^NULL,
    &  "ns1.cls1.static_meth1")
button.AddDelegateToEvent("Click", button_OnClick)
