How to add an existing feature class to a new feature dataset

Question

I have a feature class.

IFeatureClass AOIfc = AOIfws.OpenFeatureClass("BrigadeAOI");

I need to be able to put this feature class into a feature dataset that is newly created. The following line of code doesn't work for me.

IFeatureDataset AOIfd = AOIfc.FeatureDataset;

How do I accomplish this?

Answer 1

You might be able to do this using IDatasetContainer.AddDataset.

From the IDatasetContainer documentation:

The IDatasetContainer interface lets you move datasets between feature datasets and workspaces. Both objects implement the interface. It should only be used to move datasets between feature datasets and the workspace level within a single workspace, however; it cannot be used to transfer datasets from one workspace to another.
