Remarks

The OpenFeatureClass method can be used to open any existing feature class in the workspace given its fully qualified name. Note that every feature class in a geodatabase has a unique fully qualified name, and the OpenFeatureClass method can be used to directly open feature classes that are part of a feature dataset (the feature dataset name does not need to be specified).

Use the IDatabaseConnectionInfo interface to determine the User and Database (if applicable).  ISQLSyntax::QualifyTableName can be used to determine the fully qualified name for a feature class.  Use the NameExists method on the IWorkspace2 interface to determine if a feature class with the appropriate name exists in a geodatabase.

Opening a feature class that participates in a topology or geometric network will also open all other feature classes participating in the topology or geometric network in memory.
