ASP.NET - The ArrayList Object

Create an ArrayList

The ArrayList object is a collection of items containing a single data value.
Items are added to the ArrayList with the Add() method.
The following code creates a new ArrayList object named mycountries and four items are added:

-------------------------------------------------------

<script runat="server"> Sub Page_Load if Not Page.IsPostBack then   dim mycountries=New ArrayList   mycountries.Add("Norway")   mycountries.Add("Sweden")   mycountries.Add("France")   mycountries.Add("Italy") end if end sub </script> ------------------------------------------------------

By default, an ArrayList object contains 16 entries. An ArrayList can be sized to its final size with the

------------------------------------------------------
TrimToSize() method:

<script runat="server"> Sub Page_Load if Not Page.IsPostBack then   dim mycountries=New ArrayList   mycountries.Add("Norway")   mycountries.Add("Sweden")   mycountries.Add("France")   mycountries.Add("Italy")   mycountries.TrimToSize() end if end sub </script> --------------------------------------------------

An ArrayList can also be sorted alphabetically or numerically with the Sort() method:

--------------------------------------------------- <script runat="server"> Sub Page_Load if Not Page.IsPostBack then   dim mycountries=New ArrayList   mycountries.Add("Norway")   mycountries.Add("Sweden")   mycountries.Add("France")   mycountries.Add("Italy")   mycountries.TrimToSize()   mycountries.Sort() end if end sub </script> ----------------------------------------------------

To sort in reverse order, apply the Reverse() method after the Sort() method:

----------------------------------------------------

<script runat="server"> Sub Page_Load if Not Page.IsPostBack then   dim mycountries=New ArrayList   mycountries.Add("Norway")   mycountries.Add("Sweden")   mycountries.Add("France")   mycountries.Add("Italy")   mycountries.TrimToSize()   mycountries.Sort()   mycountries.Reverse() end if end sub </script> -------------------------------------------------
