About accessing a raster dataset in a raster catalog

[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
