c# - 如何使用c#从gmail读取电子邮件

Question

我想创建窗口应用程序，通过它我可以从 gmail 读取电子邮件。

实际上我想阅读电子邮件的正确格式，例如收件人、发件人、主题、抄送和正文。

        using (Imap imap = new Imap())
        {
            imap.ConnectSSL("mail.company.com");
            imap.Login("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="61000f06040d3e1821020e0c11000f184f020e0c" rel="noreferrer noopener nofollow">[email protected]</a>", "xyx***");

            imap.SelectInbox();
            List<long> uids = imap.SearchFlag(Flag.Unseen);
            foreach (long uid in uids)
            {
                string eml = imap.GetMessageByUID(uid);
                IMail message = new MailBuilder()
                    .CreateFromEml(eml);

                Console.WriteLine(message.Subject);
                Console.WriteLine(message.TextDataString);
            }
            imap.Close(true);
        }    

就是这个错误。无法建立连接，因为目标机器主动拒绝

尝试一下，我已添加端口号以及用于连接到服务器的 gmail imap 服务器

    using (Imap imap = new Imap())
    {
        imap.ConnectSSL("imap.gmail.com", 993);
        imap.Login("<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="d5b4bbb2b0b98aac95b6bab8a5b4bbacfbb6bab8" rel="noreferrer noopener nofollow">[email protected]</a>", "xyx***"); // MailID As Username and Password

        imap.SelectInbox();
        List<long> uids = imap.SearchFlag(Flag.Unseen);
        foreach (long uid in uids)
        {
            string eml = imap.GetMessageByUID(uid);
            IMail message = new MailBuilder()
                .CreateFromEml(eml);

            Console.WriteLine(message.Subject);
            Console.WriteLine(message.TextDataString);
        }
        imap.Close(true);
    }
