Question

The documentation (and intellisense) states very clearly that DataTable implements IListSource. But then why doesn’t DataTable have a getList() method, which is (the main) part of the IListView interface?

Answer 1

DataTable uses Explicit Interface Implementation to implement IListSource.

You can still use the method via:

 IListSource listSource = (IListSource)dataTable;
 IList list = listSource.GetList();
