using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
/*CREDENTIAL CLASS' NAMESPACE*/
using System.Net;
using OpenContactsNet;

namespace WebApplication1
{
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        OpenContactsNet.GmailExtract gm = new OpenContactsNet.GmailExtract();
        NetworkCredential nw = new NetworkCredential("tresorunikin@gmail.com", "titinik");
        OpenContactsNet.MailContactList ml = new OpenContactsNet.MailContactList();
        gm.Extract(nw, out ml);
//Triyng to Show somethin
        Response.Write(ml.Count+" Contacts : ");
        foreach(MailContact mc in ml){
            Response.Write(mc.Email+"

        }
