我是什么尝试过：

What I have tried:

string pweda = "password"; //(ConfigurationManager.AppSettings["password"]);
string from = "[e-mail]"; //Replace this with your own correct Gmail Address
string to = "[e-mail]"; 
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
            mail.To.Add(to);
            mail.From = new MailAddress(from);
            mail.Subject = "This is a test mail";
            mail.SubjectEncoding = System.Text.Encoding.UTF8;
            mail.Body = "Test Mail.";

            mail.Priority = MailPriority.High;
            SmtpClient client = new SmtpClient();

            //Add the Creddentials- use your own email id and password
            client.UseDefaultCredentials = false;
            client.Credentials = new System.Net.NetworkCredential(from, pweda);
            client.Port = 587; // Gmail works on this port
            client.Host = "smtp.gmail.com";
            client.EnableSsl = true; //Gmail works on Server Secured Layer

            try
            {
                client.Send(mail);
                Response.Write("Message Sent...");
            }
            catch (Exception ex)
            {
                Exception ex2 = ex;
                string errorMessage = string.Empty;
                while (ex2 != null)
                {
                    errorMessage += ex2.ToString();
                    ex2 = ex2.InnerException;
                }
                HttpContext.Current.Response.Write(errorMessage);
            }
