If you want to bind dropdownlist using array in asp.net then first add item to the array on page_Load event.
After that pass dataSource as array name to DropdownList. lets take a simple example for binding dropdownlist on page load.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
             Height="23px"
            Width="173px">
        </asp:DropDownList>
