my   desing

It is so easy!

Read this : http://code.google.com/intl/fr-CA/apis/contacts/docs/2.0/developers_guide_dotnet.html

Code (C#):

using System;
using Google.GData.Contacts;
using Google.GData.Client;
using Google.GData.Extensions;
using Google.Contacts;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        RequestSettings rs = new RequestSettings("exampleCo-exampleApp-1", "your_Google_account_email", "your_password");

        // AutoPaging results in automatic paging in order to retrieve all contacts
        rs.AutoPaging = true;
        ContactsRequest cr = new ContactsRequest(rs);

        Feed<Contact> f = cr.GetContacts();
        foreach (Contact c in f.Entries)
        {
            //Response.Write(c.Title);
            foreach (EMail email in c.Emails)
            {
                Response.Write(email.Address);
            }
            //foreach (GroupMembership g in c.GroupMembership)
            //{
            //    Response.Write("<br/>" + g.HRef);
            //}
            //foreach (IMAddress im in c.IMs)
            //{
            //    Response.Write("<br/>" + im.Address);
            //}
            Response.Write("<br/><br/>");
        }

    }
}

i tried this code.

I did not get what is the utility .please let us know.

its a dll or name space etc 

Hi gopiiipl,

As i said, you have to read : http://code.google.com/intl/fr-CA/apis/contacts/docs/2.0/developers_guide_dotnet.html

You must install the "Google Data API Setup(1.4.0.2).msi"
