how to include cc copy in email notification - asp.net-mvc

Question

How am I include the sender/creator in email notification in my project?
This code is working fine and it notifies all the persons tagged in Assigned To textfield. And now how can I include in CC copy the person who created the report?.
The string created_by is the employee number of the person who created the report and the ad_users table is where all the employee number and email addresses can be found. How can I get the email address of the person who created the report?
public void SendEmail(Guid[] UsersID,
string ir_no,
string place,
int? hn,
int? age,
string gender,
string persons_involved,
string incidentName,
string narrative_report,
DateTime? created_date,
string created_by,
Guid IRID)
{
var Host = ConfigurationManager.AppSettings["SmtpClient"].ToString();
var password = ConfigurationManager.AppSettings["SmtpPassword"].ToString();
var FromEmailID = ConfigurationManager.AppSettings["FromMail"].ToString();
var port = ConfigurationManager.AppSettings["Port"].ToString();
var username = ConfigurationManager.AppSettings["Username"].ToString();
var incident_name = (from i in db.All_Issues
select i.Incident_Patient_Name);
//Users already Activated the accounts
MailMessage mail = new MailMessage();
mail.From = new MailAddress(FromEmailID);
//MailAddress copy = new MailAddress(irCreatorEmail);
//mail.CC.Add(copy);
mail.Subject = "Sample Email";
mail.IsBodyHtml = true;
mail.BodyEncoding = System.Text.Encoding.GetEncoding("utf-8");
//Users not yet Activated
MailMessage mail2 = new MailMessage();
mail2.From = new MailAddress(FromEmailID);
//MailAddress copy2 = new MailAddress(irCreatorEmail);
//mail2.CC.Add(copy2);
mail2.Subject = "Sample Email";
mail2.IsBodyHtml = true;
mail2.BodyEncoding = System.Text.Encoding.GetEncoding("utf-8");
SmtpClient smtpclient = new SmtpClient();
smtpclient.Host = Host;
smtpclient.Port = Convert.ToInt32(port);
smtpclient.Credentials = new System.Net.NetworkCredential(username, password);
smtpclient.EnableSsl = true;
List<ad_users> users = db.ad_users.ToList();
if (UsersID != null)
{
foreach (var Users in UsersID)
{
foreach (var usersList in users)
{
if (Users == usersList.user_id)
{
var adUsersList = db.ad_users.Find(Users);
var emp = adUsersList.employee_nr;
if (emp != null)
{
mail.Body = EmailMessage(ir_no,
place,
hn,
age,
gender,
persons_involved,
incidentName,
narrative_report,
created_date,
created_by,
IRID);
mail.To.Add(usersList.email_address);
}
else
{
mail2.Body = EmailMessageNotActivated(ir_no,
place,
hn,
age,
gender,
persons_involved,
incidentName,
narrative_report,
created_date,
created_by,
IRID);
mail2.To.Add(usersList.email_address);
}
}
}
}
try
{
smtpclient.Send(mail);
smtpclient.Send(mail2);
}
catch (InvalidOperationException /*ex*/)
{
//ModelState.AddModelError("", ex);
}
}
}
Thank you in advance.

Already found the solution in this problem. Just took a long time for posting here for update.
I found the answer by using a Helper wherein, I can get the email of the creator.
public static string GetEmailOfIRCreator(this string empNo)
{
IREntities dbIMR = new IREntities();
var email = dbIMR.ad_users.Where(a => a.employee_nr == empNo).Select(a => a.email_address).FirstOrDefault();
return email;
}
Then I use this helper in my class on sending email notification.
var irCreator = created_by_emp_nr.GetEmailOfIRCreator();
if (mail.To.Count > 0)
{
if (irCreator != null)
{
mail.CC.Add(new MailAddress(irCreator));
}
client.Send(mail);
}
And that's it. I already send an email notification to creator as cc copy.
Hoping this can also help someone.
