                //Create object of System.Net.Mail.MailMessage

                MailMessage email = new MailMessage();

                SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");

                //Sender Address

                email.From = new MailAddress(txtFrom.Text);

                //Receiver Address

                email.To.Add(TxtTo.Text);

                email.Subject = TxtSubject.Text;

                email.Body = txtMessage.Text;

                //Email Attachment

                if (linkLabel1.Text.Trim() != "")

                {

                    System.Net.Mail.Attachment attachment;

                    attachment = new System.Net.Mail.Attachment(linkLabel1.Text);

                    email.Attachments.Add(attachment);

                }

              

                SmtpServer.Port = 587; //  Gmail SMTP Port

                //Sender User/Password.

                SmtpServer.Credentials = new System.Net.NetworkCredential(txtUser.Text.Trim(), txtPassword.Text.Trim());

                SmtpServer.EnableSsl = true;

                SmtpServer.Send(email);

                linkLabel1.Text = "";

                MessageBox.Show("send Successfully.");

            }

            catch (Exception ex)

            {

                MessageBox.Show(ex.ToString());

            }

        }
