    MailMessage myMessage = new MailMessage();
    myMessage.Subject = "Test Message";
    myMessage.Body = "Hello World";
    myMessage.From = new MailAddress("willrathlou3@gmail.com", "Will");
    myMessage.To.Add(new MailAddress("willrathlou3@gmail.com", "Will"));



    SmtpClient mySmtpClient = new SmtpClient("smtp.gmail.com");

Answer 1

您需要像這樣設置NetworkCredential。

client.Credentials = new NetworkCredential（“用戶名”，“密碼”）;

您的代碼應如下所示。

    MailMessage myMessage = new MailMessage();
    myMessage.Subject = "Test Message";
    myMessage.Body = "Hello World";
    myMessage.From = new MailAddress("willrathlou3@gmail.com", "Will");
    myMessage.To.Add(new MailAddress("willrathlou3@gmail.com", "Will"));

    SmtpClient mySmtpClient = new SmtpClient("smtp.gmail.com");
    mySmtpClient .Credentials=new NetworkCredential("username", "password");

    mySmtpClient.Send(myMessage);
