C # ComboBox.Items is a property or array?

This question already has an answer here:

  • What is the use of Indexers? 5 answers

Reference to Microsoft Developer Network, ComboBox.Items Property syntax is

public ComboBox.ObjectCollection Items { get; }

It show me that ComboBox.Items will return an object. And that I can use this object add/remove... method to maintain combobox content

But why I can use ComboBox.Items[index] array to return value to me for example, ComboBox.Items[0].Text

So, I don't understand items is a property or is a array.


ComboBox.ObjectCollection is property which has a return type that supports indexing and is collection.

This type implements all these interfaces, which makes it a collection and allows you to do indexing on it.

Public Class ObjectCollection
    Implements IList, ICollection, IEnumerable
