c# - 无法在 C# 中使用 Gmail SMTP 发送邮件

Question

mailMessage.From = new MailAddress(fromEmailAddress);
        mailMessage.Subject = "Test";
        mailMessage.Body = "Manish";
        mailMessage.IsBodyHtml = true;
        mailMessage.To.Add(new MailAddress(toEmailAddress));
        SmtpClient smtp = new SmtpClient("smtp.gmail.com", 465);          
        smtp.EnableSsl = true;
        System.Net.NetworkCredential NetworkCred = new System.Net.NetworkCredential();
        NetworkCred.UserName = userNAme;
        NetworkCred.Password = password;
        smtp.UseDefaultCredentials = true;
        smtp.Credentials = NetworkCred;
        smtp.Send(mailMessage);

我正在尝试配置 Gmail SMTP 并尝试使用 TSL 和 SSL，但上面的代码总是抛出超时异常

我认为您需要将 usedefaultcredentials 设置为 false。否则将不会使用您在网络凭据中设置的用户名/密码。
