C# Windows Form Application - Send email using gmail smtp
提问by noobie
I have been trying to create a small program to send email through smtp.gmail.com, but it always prompt me that "The operation has timed out". I know there are lots of solutions available on the net but none of it works.
我一直在尝试创建一个通过smtp.gmail.com发送电子邮件的小程序，但它总是提示我“操作已超时”。我知道网上有很多解决方案，但没有一个有效。
try
{
MailMessage message = new MailMessage();
SmtpClient smtp = new SmtpClient();
message.From = new MailAddress("[email protected]");
message.To.Add(new MailAddress("[email protected]"));
message.Subject = "Test";
message.Body = "Content";
smtp.Port = 465;
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.Credentials = new NetworkCredential("[email protected]", "pwd");
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Send(message);
}
catch (Exception ex)
{
MessageBox.Show("err: " + ex.Message);
}
Is there any way to solve this?
有没有办法解决这个问题？
