email.Body = Message;
SmtpClient smtp = new SmtpClient(host, port);
smtp.UseDefaultCredentials = false;
NetworkCredential nc = new NetworkCredential(txtFrom.Text.Trim(), password);
smtp.Credentials = nc;
smtp.EnableSsl = true;
email.IsBodyHtml = true;
email.To.Add(to);
string fileName = "";
if (FileUpload1.PostedFile != null)
{
HttpPostedFile attchment = FileUpload1.PostedFile;
int FileLength = attchment.ContentLength;
if (FileLength > 0)
{
fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
FileUpload1.PostedFile.SaveAs(Path.Combine(Server.MapPath("~/EmailAttachment"), fileName));
Attachment attachment = new Attachment(Path.Combine(Server.MapPath("~/EmailAttachment"), fileName));
email.Attachments.Add(attachment);
