Remarks
The IFeatureDatasetExtension interface is used to return a reference to the feature dataset associated with the extension. A reference to IFeatureDatasetExtension can be obtained by using the IFeatureDatasetExtensionContainer::FindExtension method with the appropriate esriDatasetType.
The following code demonstrates how to get a reference to the IFeatureDatasetExtension in order to create a network dataset. It assumes you have a reference to the feature dataset (pFDS) in which the network dataset will be created and populated data element (pDENDS).
public void esriGeoDatabase__IFeatureDatasetExtension(IFeatureDataset featureDataset, IDEDataset deDataset)
{
// Cast to the IFeatureDatasetExtensionContainer interface
IFeatureDatasetExtensionContainer featuredatasetextensionContainer = (IFeatureDatasetExtensionContainer)featureDataset;
// Get a reference to the feature dataset extension for network datasets
IFeatureDatasetExtension featuredatasetExtension = featuredatasetextensionContainer.FindExtension(esriDatasetType.esriDTNetworkDataset);
IDatasetContainer2 datasetContainer2 = (IDatasetContainer2)featuredatasetExtension;
IDataset dataset = datasetContainer2.CreateDataset(deDataset);
