Provides access to members that have information about the workspace.
The IWorkspace2 interface provides the NameExists method that facilitates determining the existance of the specified type of dataset with the supplied name. IWorkspace2 is only implemented for geodatabases and (at versions later than 9.3.1) shapefile workspaces.
|Indicates if a dataset with the given name exists within the workspace.

NameExistsallows you determine if a dataset of the specified type and the supplied name already exists within the Workspace. When the name string parameter is not qualified, NameExists will return True if any objects of the specified dataset type exists in the Workspace with the current user as the owner. When a fully qualified name parameter is specified, NameExistswill return True if an object of the specified dataset corresponds to the qualified name (on ArcSDE geodatabases a fully qualified name would be databasename.username.tablename). NameExistswill also consider tables that are not registered with the geodatabase.
The specified type must be supplied, the esriDTAny value is not supported.
If you would like to find out if a specific feature class exists in a feature dataset you should loop through the results of IFeatureClassContainer::ClassByName as NameExists will always check the entire Workspace for the existance of the feature class.
