Inheriting from CollectionBase
The first step necessary to implement a strongly typed collection is to define a class that generalizes CollectionBase. (You also can inherit from ReadOnlyCollectionBase, to implement a read-only version of the strongly typed collection.) Listing 1 demonstrates how to inherit from the CollectionBase class; we'll assume that we're defining a beer selection collection for a bar franchise, perhaps "Pauly's".
Listing 1—Inherit from System.Collections.CollectionBase to Create a Strongly Typed Collection
public class BeerInventory : System.Collections.CollectionBase
{
}
Listing 1 demonstrates the basic syntax for expressing an inheritance relationship. (The same syntax is used when you want to implement an interface.)
