.net - 向主机 'smtp.gmail.com' 发送电子邮件总是出错

Question

我正在尝试以编程方式发送电子邮件，但我不断收到以下错误:

The remote name could not be resolved: 'smtp.gmail.com'

这是我正在尝试的代码:

string sender = "example@gmail.com";
string password = "myPwd";
string host = "smtp.gmail.com";
int port = "587";
MailMessage mail = new MailMessage();
SmtpClient smtpServer = new SmtpClient();
smtpServer.Host = host;
mail.From = new MailAddress(sender);
mail.To.Add(recipient);
mail.Subject = emailSubject;
mail.Body = body;
mail.IsBodyHtml = true;
smtpServer.Port = port;
smtpServer.Credentials = new NetworkCredential(sender, password);
smtpServer.EnableSsl = true;
smtpServer.Send(mail);

我一直在尝试，但我不明白哪里出了问题。谁能帮忙？
