error cannot implicitly convert type 'string' to System.Net.Mail.MailAddressCollection

Split the string on the char ';'

string[] Addresses = s.Split(';');

and then:

MailMessage msg = new MailMessage();
foreach (string address in Addresses)
   msg.To.Add(address);

User following code to send email to multiple recipients,

MyMsg.To.Add(new System.Net.Mail.MailAddress(ToEmail));

I think you need to create a MailAddressCollection and add the email addresses to that collection with new MailAddress("emailadres@domain.extension", "mysite"); Then you assign the collection to the To property of the MailMessage object. It could be you need to split the string on the ";" character and add them to the collection with a for loop.

Basically do the same as this line:

MyMsg.From = new MailAddress("info@mysite.net", "mysite");

but then with the MailAddressCollection.

Hope this helps.

This code below will work fine for you:

public static void SendBulkMail(Shooter sender, List<string> receiversList, string mailtext)
        {
            MailMessage email = new MailMessage();
            email.From = new MailAddress(sender.Mailaddress, string.Format("{0}, {1}", sender.Lastname, sender.Surname));
            foreach (string receiver in receiversList)
            {
                email.Bcc.Add(new MailAddress(receiver));
            }
            email.Subject = string.Format("SMGT BulkMail von {0} {1}", sender.Lastname, sender.Surname);
            email.IsBodyHtml = false;
            email.Body = string.Format("{0}\n\n\n--> Diese Email-Nachricht wurde als BulkMail vom SMGT Web-Portal gesendet. Absender ist {1} {2} ({3} - {4})\n\nDa es sich um ein BulkMail handelt sind alle Empfänger im BCC-Feld aufgeführt",
                                        mailtext, sender.Lastname, sender.Surname, sender.HomeShootingClub.Name, sender.HomeShootingClub.City);
            SmtpClient client = ConnectSmtpClient();
            client.Send(email);
        }

        private static SmtpClient ConnectSmtpClient()
        {
            SmtpClient client = new SmtpClient();
            client.Port = 587;
            client.EnableSsl = true;
            client.DeliveryMethod = SmtpDeliveryMethod.Network;
            client.UseDefaultCredentials = false;
            client.Credentials = new NetworkCredential("someone@gmail.com", "password");
            client.Host = "smtp.gmail.com";
            return client;
        }

Shooter is a class to represent a person.
