Google.GData.Contacts将联系人添加到Gapps

我正在尝试将联系人添加到Gapps联系人。我尝试了下面的代码。它成功地将联系人添加到Google帐户，没有任何错误。但它不会在帐户中显示添加的联系人。这是我添加联系人的代码

                 credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                new ClientSecrets
                {   
                    ClientId = clientId,
                    ClientSecret = clientSecret
                },
                Scopes = new string[] { "http://www.google.com/m8/feeds/" },
                "user",
                CancellationToken.None,
                new FileDataStore(credPath, true)).Result;
            var token = credential.Token.AccessToken;

            string RedirectURI = "urn:ietf:wg:oauth:2.0:oob";
            OAuth2Parameters parameters = new OAuth2Parameters
            {
                ClientId = clientId,
                ClientSecret = clientSecret,
                // Note: AccessToken is valid only for 60 minutes
                AccessToken = token,
                RefreshToken = credential.Token.RefreshToken,
                RedirectUri = RedirectURI
            };
            RequestSettings settings = new RequestSettings(
                "AppName", parameters);
            ContactsRequest cr = new ContactsRequest(settings);

                Contact newContact = new Contact();
                newContact.Name = new Name()
                {
                    FullName = "Elizabeth Bennet",
                    GivenName = "Elizabeth",
                    FamilyName = "Bennet",
                };
                newContact.Content = "Notes";
                // Set the contact's e-mail addresses.
                newContact.Emails.Add(new EMail()
                {
                    Primary = true,
                    Rel = ContactsRelationships.IsHome,
                    Address = "something@gmail.com"
                });
                newContact.Emails.Add(new EMail()
                {
                    Rel = ContactsRelationships.IsWork,
                    Address = "something@gmail.com"
                });
                newContact.Location = "Pune";
                Uri feedUri = new Uri(ContactsQuery.CreateContactsUri("default"));

                Contact createdContact = cr.Insert(feedUri, newContact); // Is Successfull 
            }`

当我获取联系人时，它会在结果中为我添加联系人。请提出问题的解决方案。

string str = createdContact.Id;
                Feed<Contact> f = cr.GetContacts();
                foreach (Contact c in f.Entries)
                {
                    Console.WriteLine(c.Name.FullName);
                }

谢谢;雷努卡。
