VB.NET Core Classes in a Nutshell

Name

IList

Synopsis

This interface defines the basic characteristics of an indexable collection of objects. All array and collection classes implement this interface. IList defines methods by adding an element to the end of a list (Add()), inserting or removing an element at a specific index (Insert() and RemoveAt()), or removing all elements. Remove() removes the first occurrence of a specific object from a list. Changing the elements of a list requires that the class be resizable and modifiable (see the IsFixedSize property). The Contains() method checks to see if a given value is contained in the list, while IndexOf() returns the index of an existing list value.
