Parameters

• method
  Name of the event delegate.

• args
  Object array of the arguments taken by the delegate.

Remarks

Called by the service objects to fire an event. Invoke uses the value of the SynchronizingObject property to marshal the event to the correct thread. If SynchronizingObject is set to null, the event is fired on the calling thread.

Note

Invoke is only used by service objects that do not derive from either the device’s basic or base class.
