c# - C# および ASP.NET で Google Contacts API バージョン 3.0 および OAuth 2.0 を使用して連絡先を追加する

Question

開発者のアカウントを作成し、クライアント ID と秘密鍵を取得しました。私は C# を初めて使用します。C# を使用して連絡先を取得できます。新しい連絡先エントリを追加するためのコードを投稿できますか? Google にはこの目的に関する適切なドキュメントがありますが、C# を使用して実装するには問題があります。助けてください！

ありがとうございました

PHP を使用して達成できた (連絡先の追加)

ここにコードがあります

<?php

$group_id = "6"; // Used as the default 'My Contacts' group.

require_once 'google-api-php-client/src/Google_Client.php';

session_start();

$client = new Google_Client();
$client->setApplicationName("Google Apps PHP Starter Application");
$client->setScopes(array(
'https://apps-apis.google.com/a/feeds/groups/',
'https://apps-apis.google.com/a/feeds/alias/',
'https://apps-apis.google.com/a/feeds/user/',
'https://www.google.com/m8/feeds/',
'https://www.google.com/m8/feeds/user/',
 ));


$client->setClientId('#################################');
$client->setClientSecret('***************************');
$client->setRedirectUri('http://localhost/try/index.php');
$client->setDeveloperKey('DEVELOPER_KEY');

if (isset($_REQUEST['logout'])) {
unset($_SESSION['access_token']);
}

if (isset($_GET['code'])) {
$client->authenticate();
$_SESSION['access_token'] = $client->getAccessToken();
$redirect = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];
header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));
}

if (isset($_SESSION['access_token'])) {

$client->setAccessToken($_SESSION['access_token']);
$token = json_decode($_SESSION['access_token']);


$auth_pass = $token->access_token;



//Get Email of User ------------------------------------

$xml = simplexml_load_string($response); // Convert to an ARRAY
