.NET Windows Forms in a Nutshell

This interface is implemented by classes (such as System.Data.DataSet and System.Data.DataTable ) that can provide one or more lists for a data-binding scenario but are not actually bindable lists in and of themselves .

The ContainsListCollection property determines whether the list is actually a collection of lists itself (as in the System.Data.DataSet - System.Data.DataTable relationship), and the GetList() method returns the System.Collections.IList for the binding scenario.

public interface IListSource { // Public Instance Properties public bool ContainsListCollection {get; } // Public Instance Methods public IList GetList (); }
