        SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
        smtp.UseDefaultCredentials = false;
        smtp.Credentials = new NetworkCredential("yourMail", "yourPassword");
        smtp.EnableSsl = true;

        MailMessage msg = new MailMessage(sendFrom, "yourMail");

        msg.ReplyToList.Add(sendFrom);
        msg.Subject = subject;
        msg.Body = bodyTxt;
        System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment(@"C:\Projects\EverydayProject\test.txt");
        msg.Attachments.Add(attachment);

        smtp.Send(msg);

以下是向gmail smtp发送电子邮件的工作代码。从我看到你没有设置UseDefaultCredentials = false，你使用了错误的端口。 你也不能覆盖这样的异常。，抛出初始异常。此外，您还需要关闭Gmail帐户中的安全设置。你可以谷歌。

使用asp.net中的smtp端口465向gmail帐户发送邮件时超时错误
