Asp.Net(C#)送信Emailの使い方


私たちはよくwebプログラムを書いてメールを送る機能を使います.ここでは届出をします.実はこの機能は簡単で、まずWebでconfigのに追加:
 <system.net>
    <mailSettings>
      <smtp deliveryMethod="Network" from="[email protected]" >
        <network host="localhost" defaultCredentials="false" userName="[email protected]" password="passowrd"/>
      </smtp>
    </mailSettings>
  </system.net>

プログラムコード:
SmtpSection cfg = ConfigurationManager.GetSection(@"system.net/mailSettings/smtp") as SmtpSection;
SmtpNetworkElement smtElement = cfg.Network;
//                
MailMessage email; 
string displayName="xxxx"; //email     
if (string.IsNullOrEmpty(displayName))
{
	email = new MailMessage(_FromEmail, _ToEmail);
}
else
{
	MailAddress fromMail = new MailAddress(_FromEmail, displayName, System.Text.Encoding.UTF8);
	MailAddress toMail = new MailAddress(_ToEmail);
	email = new MailMessage(fromMail, toMail);
	//email.Sender = new MailAddress(_FromEmail, displayName, System.Text.Encoding.UTF8);
}
email.IsBodyHtml = isHtml;
email.Body = _Body;
email.Subject = _Subject;
email.BodyEncoding = System.Text.Encoding.UTF8;
//   smtp     ,            
System.Net.Mail.SmtpClient stmp = new SmtpClient(smtElement.Host);
//                ,        credentials        
if (smtElement.DefaultCredentials)
{
	stmp.UseDefaultCredentials = true;
	stmp.Credentials = new System.Net.NetworkCredential(smtElement.UserName, smtElement.Password);
}
//        
stmp.Send(email);
