Just a sammple, i have used Ado.Net you can use EF or whatever you want private void SendActivationEmail(int userId) { string constr = ConfigurationManager.ConnectionStrings[ "constr" ].ConnectionString; string activationCode = Guid.NewGuid().ToString(); using (SqlConnection con = new SqlConnection(constr)) { using (SqlCommand cmd = new SqlCommand( "INSERT INTO UserActivation VALUES(@UserId, @ActivationCode)" )) { using (SqlDataAdapter sda = new SqlDataAdapter()) { cmd.CommandType = CommandType.Text; cmd.Parameters.AddWithValue( "@UserId" , userId); cmd.Parameters.AddWithValue( "@ActivationCode" , activationCode); cmd.Connection = con; con.Open(); cmd.ExecuteNonQuery(); con.Close(); } } } using (MailMessage mm = new MailMessage( "sender@gmail.com" , txtEmail.Text)) { mm.Subject = "Account Activation" ; string body = "Hello " + txtUsername.Text.Trim() + "," ; body += " Please click the following link to activate your account" ; body += " + Request.Url.AbsoluteUri.Replace( "CS.aspx" , "CS_Activation.aspx?ActivationCode=" + activationCode) + "'>Click here to activate your account. " ; body += " Thanks" ; mm.Body = body; mm.IsBodyHtml = true; SmtpClient smtp = new SmtpClient(); smtp.Host = "smtp.gmail.com" ; smtp.EnableSsl = true; NetworkCredential NetworkCred = new NetworkCredential( "sender@gmail.com" , " " ); smtp.UseDefaultCredentials = true; smtp.Credentials = NetworkCred; smtp.Port = 587 ; smtp.Send(mm); } } Public Void Registration(user user) { // save int database // fetch userId SendActivationEmail(user.userId); }
