Detect if a FGDB table/featureclass is compressed

Is it possible to detect if a file geodatabase table/feature class is compressed or uncompressed using code (preferably C#)?

I got this from a colleague:

        public static Boolean IsCompressed(IDataset dataset)
        {
           // Check the table's workspace type.
           IWorkspace workspace = dataset.Workspace;
           WorkspaceType workspaceType = GetWorkspaceType(workspace);
           if (workspaceType == WorkspaceType.FileGDB)
           {
              // Get the dataset's property set and check the "Datafile Format" property.
              IPropertySet propertySet = dataset.PropertySet;
              if (propertySet != null)
              {
                 try
                 {
                    object propertyValue = propertySet.GetProperty("Datafile Format");
                    esriFGDBDatafileFormat datafileFormat = (esriFGDBDatafileFormat)propertyValue;
                    if (datafileFormat == esriFGDBDatafileFormat.esriFGDBCompressedDatafile)
                    {
                       return true;
                    }
                 }
                 catch (InvalidCastException) { }
              }
           }
           return false;
        }

He notes that FileGDB workspaces and feature datasets do not know if they are in a compressed file geodatabase, only tables and feature classes.
