Question

Hi i am trying to send am email after Button click in Asp.net.

The emails to send the email to will be retrieved from a query.

        string connectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
        SqlDataReader reader;
        string sendMessage = "SELECT aspnet_Membership.Email FROM aspnet_Membership join User_Profile on User_Profile.UserId = aspnet_Membership.UserId JOIN Project_List on Project_List.ProfileId = User_Profile.ProfileId WHERE Project_List.ProfileId = 1";

        using (SqlConnection myConnection = new SqlConnection(connectionString))
        {
            myConnection.Open();
            SqlCommand myCommand = new SqlCommand(sendMessage, myConnection);



            ArrayList emailArray = new ArrayList();
            reader = myCommand.ExecuteReader();


            while (reader.Read())
            {
                emailArray.Add(reader["email"]);
            }

            foreach (string email in emailArray)

it doesn't come up with any errors, and i don't receive any emails

This code should work:

foreach(string email in emailArray)
{
     SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
     smtp.UseDefaultCredentials = false;
     smtp.Credentials = new NetworkCredential("tayyib@gmail.com", "xxxxxxxxx");
     smtp.EnableSsl = true;

     MailMessage msg = new MailMessage("tayyib@gmail.com", email); 
     msg.Subject = "Test1";
     msg.Body = "Test2";

     smtp.Send(msg);
 }

There is security setting which you should turn off in your gmail account.

EDIT: Like I said you should TURN OFF security setting in gmail account ! If this link doesn't help you just google the exception ! Check the Link ! Or this LINK
