使用jmail組件寄送電子郵件(C#)

首先，下載jmail組件，可以直接安裝；也可以找到jmail.dll，手動註冊組件。命令列環境下，到jmail.dll所在目錄，運行regsvr32 jmail.dll，C＃程式中，行首加上using jmail,如下：(點擊btnSend按鈕後發送郵件)
using jmail;

private void btnSend_Click(object sender, System.EventArgs e)
{
jmail.Message jmessage=new jmail.MessageClass();
jmessage.Charset="GB2312";
jmessage.From="fromuser@benq.com";
jmessage.FromName= "eric lv" ;
jmessage.ReplyTo="replayto@benq.com";
jmessage.Subject="test email from jmessage";
jmessage.AddRecipient("receiver@benq.com" ,"eric lv","123");
jmessage.Body= "jmail 內容" ;
jmessage.MailServerUserName= "eric lv" ;
jmessage.MailServerPassWord= "user password" ;
jmessage.Send("smtp-server",false) ;
MessageBox.Show("email sent successfully!");
jmessage.Close() ;
}
