Casting EventTypes (ComServer Wrapper)|OPC UA Implementation: Stacks, Tools, and Samples|Forum|OPC Foundation

Hi there,

I'm developing a small OPC UA Client (using .NET SDK) to access COM AE Server through the COMServerWrapper included in .NET SDK. The AE Server offers some different event types with additional event information accessible through attributes.

Now, when I create a subscription to the wrapped AE Server in my client, I get the events as COMAEBaseEventType with the fields (eventId, eventType, severity, etc...). The eventType field points to a subtype node, named after the correct AE event type. If I'm browsing this eventType, I see the AE event attributes as properties of type variable.

If I'm getting the monitoredItem.Notification as EventFieldList I only see the standard AE event fields. The question is, how do I "cast" this notification to the correct event type and read the special attributes?

I created some types with the ModelCompiler representing the different event types, but see no possibility to use these types. A little advice would be appreciated.
