我正在尝试检索我的用户登录任何 Google 应用程序服务（如 Gmail）的最近日期（或通过移动设备/imap/pop 等为他们完成此操作）。我是 Google Apps for Education 的域管理员并使用 C# gdata-api。
我想回收学生用户名，如果他们已经离开超过一年而没有登录他们的 gmail 应用程序，并且需要最后访问日期来完成此操作。
请让我知道这是否可能
谢谢你。

我使用了 gmail 报告 API。我忘记了我从哪里得到的，但我从某个地方偷了它。如果你知道在哪里，请留下评论链接。

要使用它：
ReportsManager reports = new ReportsManager("*", "*", "*");
reports.ClientLogin();
Dictionary<string, ArrayList> accountReport = reports.getReport(ReportsManager.ReportType.accounts, DateTime.Today);
int count = accountReport["account_name"].Count;
Hashtable usersLastLoggedIn = new Hashtable();
for (int i = 0; i < count; i++)
{
DateTime lastLogged = DateTime.Parse(accountReport["last_login_time"][i].ToString());
DateTime lastWebMail = DateTime.Parse(accountReport["last_web_mail_time"][i].ToString());
DateTime lastPop = DateTime.Parse(accountReport["last_pop_time"][i].ToString());
if (lastWebMail > lastLogged) { lastLogged = lastWebMail; }
if (lastPop > lastLogged) { lastLogged = lastPop; }
usersLastLoggedIn.Add(accountReport["account_name"][i].ToString().Replace('@' + ConfigurationManager.AppSettings["domain"], string.Empty), lastLogged);
}
