Here is a code...

public void MailSend(string strfrom, string strto, string strSubject, string strBody, string resumename, string sresumename)
{
    try
    {
        MailMessage msg = new MailMessage(strfrom, strto);// strEmail);

        msg.Bcc.Add("xx@xxxx.com");
        msg.Body = strBody;
        msg.Subject = strSubject;
        msg.IsBodyHtml = true;
        if (resumename.Length > 0)
        {
            Attachment att = new Attachment(Server.MapPath(VirtualPathUtility.ToAbsolute("~/User_Resume/" + resumename)));
            msg.Attachments.Add(att);
        }
        if (sresumename.Length > 0)
        {
            Attachment att1 = new Attachment(Server.MapPath(VirtualPathUtility.ToAbsolute("~/User_Resume/" + sresumename)));
            msg.Attachments.Add(att1);
        }
        System.Net.Mail.SmtpClient cli = new System.Net.Mail.SmtpClient("111.111.111.111",25);
        cli.Credentials = new NetworkCredential("nnnnnnn", "yyyyyy");
        cli.Send(msg);
        msg.Dispose();
        ScriptManager.RegisterStartupScript(this, this.GetType(), "message", "alert('Enquiery submitted sucessfully');", true);
    }
    catch (Exception ex)
    {
        ScriptManager.RegisterStartupScript(this, this.GetType(), "message", "alert('"+ex.Message+"');", true);
    }

create object of Attachment class with file name and add it into message's Attachments property

  Attachment attachment = new Attachment("file.ext");
  message.Attachments.Add(attachment);

Did you check out MailMessage.Attachments property (see MSDN)?

// create attachment and set media Type
//      see http://msdn.microsoft.com/de-de/library/system.net.mime.mediatypenames.application.aspx
Attachment data = new Attachment(
                         "PATH_TO_YOUR_FILE", 
                         MediaTypeNames.Application.Octet);
// your path may look like Server.MapPath("~/file.ABC")
message.Attachments.Add(data);
