Unable to send an email to multiple addresses/recipients using C#

I have used below code to send mail in script task

 string MailFromName = "Admin";
            System.Net.Mail.SmtpClient mailobj = new System.Net.Mail.SmtpClient();
            System.Net.Mail.MailAddress MailFrom = new System.Net.Mail.MailAddress(MailFromEmail, MailFromName);
            System.Net.Mail.MailAddress MailTo = new System.Net.Mail.MailAddress(MailToEmail, MailToEmail);
            System.Net.Mail.MailMessage mailmsg = new System.Net.Mail.MailMessage(MailFrom, MailTo);
            mailmsg.IsBodyHtml = true;
            mailmsg.Subject = strMessageSubject;
            mailmsg.Body = strMessageBody;
            mailobj.Host = strSMTPServerName;
            mailobj.Send(mailmsg);

It is working fine when I am using MailToEmail as “[e-mail]” i.e. for one email address

but this doesn’t send any mail(also it dosen’t fail) when I have multiple adress in to list

ex: “[e-mail]; [e-mail]”

How to resolve this?

EDIT New Code

 string MailFromName = "Admin";
            System.Net.Mail.SmtpClient mailobj = new System.Net.Mail.SmtpClient();
            System.Net.Mail.MailAddress MailFrom = new System.Net.Mail.MailAddress(MailFromEmail, MailFromName);
            System.Net.Mail.MailAddress MailTo = new System.Net.Mail.MailAddress(MailToEmail, MailToEmail);
            System.Net.Mail.MailMessage mailmsg = new System.Net.Mail.MailMessage(MailFrom, MailTo);
            mailmsg.IsBodyHtml = true;
            mailmsg.Subject = strMessageSubject;
            mailmsg.Body = strMessageBody;
            foreach (string str in multipleToMsg)
            {
                mailmsg.To.Add(str);
            }


            mailobj.Host = strSMTPServerName;
            mailobj.Send(mailmsg);

You’ve not shown how exactly you are adding the recipients. However to add multiple recipients you add to the “To” collection:

MailMessage message = new MailMessage();
message.To.Add("[e-mail]");

“To” is a collection of MailAddresses. Make sure you are adding it to that collection and not attempting to concatenate email addresses all into one MailAddress object.
