        MailMessage message = new MailMessage(To.Text,from.Text,subject.Text,body.Text);
        message.IsBodyHtml = true;
        SmtpClient client = new SmtpClient("smtp.gmail.com", 587);

我只是遇到了同样的问题，您必须打开“安全性较低的访问权限”。假设密码是正确的，那么您的收件箱中应该有一封电子邮件，说明这一点。这是我正在使用的代码。

public void SendEmail(string address, string attatchment)
    {
        using (MailMessage mail = new MailMessage())
        {
            mail.From = new MailAddress("FromEmail@gmail.com");
            mail.To.Add("ToEmail@gmail.com");
            mail.Subject = "Report";
            mail.Body = "Report";
            mail.IsBodyHtml = true;
            mail.Attachments.Add(new Attachment(attatchment));

            using (SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587))
            {
                smtp.Credentials = new NetworkCredential("FromEmail@gmail.com", "Password");
                smtp.EnableSsl = true;
                smtp.Send(mail);
            }
        }
    }

SMTP服务器需要安全连接，或者客户端未通过身份验证。服务器响应为：5.5.1需要身份验证
