Remarks
This read-only property will return the unique identifier for this feature class. All feature classes inside Geodatabases have a unique ID. Coverage and Shapefile feature classes do not, so IFeatureClass::FeatureClassID will always return -1 for Coverage and Shapefile feature classes. Since IFeatureClass inherits from IObjectClass, you can also get the feature class ID from IObjectClass:: ObjectClassID.
