Question

我可以在NetworkCredentials上发送电子邮件而不提供密码吗？这是我的代码。

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }
    MailMessage Myemail = new MailMessage();

    private void btnsendemail_Click(object sender, EventArgs e)
    {
        SmtpClient myGmailserver = new SmtpClient("smtp.gmail.com",587);

        myGmailserver.Credentials = new NetworkCredential("Email ID", "password");

        Myemail.From = new MailAddress("Email ID");

        Myemail.To.Add(tbTo.Text);

        Myemail.Subject = tbsubject.Text;

        Myemail.Body = tbmsg.Text;

        myGmailserver.EnableSsl = true;
        myGmailserver.Send(Myemail);
    }
}

在myGmailserver.Credentials = new NetworkCredential("Email ID", "Password");行上它要求输入该特定电子邮件的密码如果我想向某人发送电子邮件而不知道该电子邮件的密码该怎么办？请回答

您可以使用此代码

MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient();
mail.To.Add(email);
mail.From = new MailAddress("mail@domain.com");
mail.Subject = subject;
mail.IsBodyHtml = true;
mail.Body = message;
SmtpServer.Host = "smtpserver";
SmtpServer.Port = 25;
SmtpServer.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
try {
    SmtpServer.Send(mail);
}
catch (Exception ex) {
    Debug.WriteLine("Exception Message: " + ex.Message);
    if (ex.InnerException != null)
        Debug.WriteLine("Exception Inner:   " + ex.InnerException);
}
