Answer 2

你需要与Gmail进行验证定义的邮件设置SMTP：

名

var client = new SmtpClient("smtp.gmail.com", 587); 
client.EnableSsl = true; 
client.Credentials = new NetworkCredential("youraccount@gmail.com", "secret"); 

var mail = new MailMessage(); 
mail.From = new MailAddress("youraccount@gmail.com"); 
mail.To.Add("youraccount@gmail.com"); 
mail.Subject = "Test mail"; 
mail.Body = "test body"; 
client.Send(mail);
