This property provides the ability to access a specific element in the collection by using the following syntax: myCollection[index] (In Visual Basic, myCollection(index)).
The C# language uses the keyword to define the indexers instead of implementing the Item property. Visual Basic implements Item as a default property, which provides the same indexing functionality.
Retrieving the value of this property is an O(1) operation; setting the property is also an O(1) operation.
