How to bind data to dropdownlist with arrarylist in asp.net

In previous post we have discussed on how to bind the Data in Gridview,Disable dropdownlist .In this post i will show how to bind data to dropdownlist using array list in asp.net.Here i will populate drop down for city names.
<form runat=server>
<asp:DropDownList id="ddlcity" runat="server" />
We have to used ispostback to avoid the populating drop down while every time loading the page

protected void Page_Load(Object Sender, EventArgs E) 
if (!IsPostBack) {
ArrayList citynames = new ArrayList();
citynames.Add ("NewYork");
citynames.Add ("Hyderabad");
citynames.Add ("Bombay");
ddlcity.DataSource = citynames;
