mail.Fields.Add报错 不是System.Web.Mail.MailMessage成员

[ssun1999]

private void Page_Load(object sender, System.EventArgs e)
{
MailMessage mail = new MailMessage();
mail.To = "[e-mail]";
mail.From = "[e-mail]";
mail.Subject = "this is a test email.";
mail.Body = "Some text goes here";
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); //basic authentication
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "my_username_here"); //set your username here
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "super_secret"); //set your password here

SmtpMail.SmtpServer = "mail.mycompany.com"; //your real server goes here
SmtpMail.Send( mail );
}
