使用jmail组件发送电子邮件(C#)

首先，下载jmail组件，可以直接安装；也可以找到jmail.dll，手动注册组件。命令行环境下，到jmail.dll所在目录，运行regsvr32 jmail.dll，C＃程序中，行首加上using jmail,如下：(点击btnSend按钮后发送邮件)
  using jmail;

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