About accessing a raster dataset in a raster catalog

To access a raster dataset in a raster catalog, see the following code:
[C#] 
Public IRasterDataset GetRasterCatalogItem(IRasterCatalog catalog, int oid)
{
    //OID is the ObjectID of the raster dataset in the raster catalog.
    IFeatureClass featureClass = (IFeatureClass)catalog;
    IRasterCatalogItem rasterCatalogItem = (IRasterCatalogItem)
        featureClass.GetFeature(oid);
    return rasterCatalogItem.RasterDataset;
}
[VB.NET] 
Public Function GetRasterCatalogItem(ByVal catalog As IRasterCatalog, ByVal oid As Integer) As IRasterDataset
    'OID is the ObjectID of the raster dataset in the raster catalog.
    Dim featureClass As IFeatureClass = CType(catalog, IFeatureClass)
    Dim rasterCatalogItem As IRasterCatalogItem = CType(featureClass.GetFeature(oid), IRasterCatalogItem)
    Return rasterCatalogItem.RasterDataset
End Function
