The ArrayList object Implements the IList interface using an array whose size is dynamically increased as required.

The Capacity property gets or sets the number of elements that the ArrayList can contain.

The Count property gets the number of elements actually contained in the ArrayList.

The IsFixedSize property gets a value indicating whether the ArrayList has a fixed size.
