發送電子郵件到主機「smtp.gmail.com」總是示數

Question

我試圖以編程方式發送的電子郵件，我不斷收到以下錯誤：

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

這是我想要的代碼：

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); 

我總是嘗試，但我不明白髮生了什麼問題。誰能幫忙？
