Returns the unique ID of the object class.


Each feature class or table registered with the geodatabase is an object class. Object classes have a unique ID which distinguishes them from other object classes in the geodatabase. The ObjectClassID property returns this ID as a long. The object class ID is assigned by the system when the class is created, or registered with the geodatabase, it cannot be modified.

Those feature classes and tables that are in the database, but not registered with the geodatabase will always have an object class ID of -1.
