Get Google contacts via AuthSub c#

Does any one have a working example of getting google contact via AuthSub in c#

I have tried this url , but i wa开发者_C百科s not able to complete it.

Here is a piece of code from one of my projects:

    public class GoogleContactsProvider : IContactProvider
{
    #region IContactProvider Members

    /// <summary>
    /// Gets the contacts list form the contact provider.
    /// </summary>
    /// <returns></returns>
    public EntityCollection<IContactItem> GetContactsList()
    {
        EntityCollection<IContactItem> collection = new EntityCollection<IContactItem>();

        // Setup the contacts request (autopage true returns all contacts)
        RequestSettings requestSettings = new RequestSettings("AgileMe", UserName, Password);
        requestSettings.AutoPaging = true;
        ContactsRequest contactsRequest = new ContactsRequest(requestSettings);

        // Get the feed
        Feed<Contact> feed = contactsRequest.GetContacts();

        // create our collection by looping through the feed
        foreach (Contact contact in feed.Entries)
        {
            GoogleContactItem newContact = new GoogleContactItem();
            newContact.Name = contact.PrimaryEmail.Address;
            newContact.Summary = contact.Summary;

            collection.Add(newContact);
        }

        return collection;
    }

    /// <summary>
    /// Gets or sets the name of the user for the contact provider.
    /// </summary>
    /// <value>The name of the user.</value>
    public string UserName { get; set; }

    /// <summary>
    /// Gets or sets the password for the contact provider.
    /// </summary>
    /// <value>The password.</value>
    public string Password { get; set; }

    #endregion
}

EntityCollection is a wrapper around a simple List and GoogleContactItem is a wrapper around the retrieved information.

I found this example so simple. link And it works great.
