How to send mail with class (localhost)?

Question

E-mail + Attachment (vCard) send.

I have no Idea what I am doing wrong, searched for similar Questions for 2 days but no question/solution on Stackoverflow or Google fits my description.

Because I've writed my code diffrently

Send Mail + Attachment Class:

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Web.Configuration;
using System.Net.Mail;
using System.Net.Configuration;
using Compulutions.Net;
using Compulutions.Web;
using System.IO;
using System.Web.Mail;
using System.Collections.Generic;
using System.ComponentModel;
using System.Web.Services.Description;

// System.Web.Mail.SmtpMail.SmtpServer
// using System.Web.Mail.SmtpClient;


namespace vCardGenerator.Website
{
    public class SendvCard
    {
        public void MailvCard(string recipient, string filename)
        {
            Mailer smtp = new Mailer("localhost");

            /* SMTP - port 25 */

            smtp.AddAttachment(filename); //.vcf file Path
            smtp.FromAddress = new MailAddress ("random@mail.com");
            smtp.Subject = "vCard";
            smtp.MailBody = "Attachment is a vCard";
            smtp.AddRecipient(recipient);

#if !DEBUG
            try
            {
#endif
                smtp.SendMail();
#if !DEBUG
            }

            catch (Exception ex)
            {
                Response.Write("Exception Occured:   " + ex);
                    //Responds.Write("Sending vCard Failed! Please try again")
            }
#endif


            //  File.Delete(filename);

            //      vCard.vcf Delete after being send
                FileInfo DeleteFileInfo = new FileInfo(filename);

        /*  FileInfo DeleteFileInfo = new FileInfo("C:\\local\\vCardGenerator.Website" + "\\" + "FirstName_LastName" + ".vcf");
            if (DeleteFileInfo.Exists)
                File.Delete("C:\\local\\vCardGenerator.Website" + "\\" + "FirstName_LastName" + ".vcf"); */
        }
    }
}

Button Send:

protected void btnSend_Click(object sender, EventArgs e)
{
// Send mail with attachment
using (Attachment data = new Attachment("C:\\local\\vCardGenerator.Website\\" + "FirstName_LastName.vcf", MediaTypeNames.Application.Octet))
{

SendvCard smtp = new SendvCard();
}

lblStatus.Text = "Send to:" + " " + txtMail.Text;

FileInfo DeleteFileInfo = new FileInfo("C:\\local\\vCardGenerator.Website" + "\\" + "FirstName_LastName" + ".vcf");
if (DeleteFileInfo.Exists)
File.Delete("C:\\local\\vCardGenerator.Website" + "\\" + "FirstName_LastName" +".vcf");
  }
 }
}

Willing to provide any other/more information if needed.

Trying to get help of the professionals so atleast give me an solution, before burning me.

Sincerely,
Hopeless Creature.

Looks like you have only created an instance of SendvCard and are not invoking the send method in the class (MailvCard).

 SendvCard smtp = new SendvCard();

 smtp.MailvCard("user@domain.com", "filename"); // calls the method on the class
