foreach (Rules rl in global_rules)
                {
                    if (rl._ratingtype == "Equal to")
                    {
                        if (Convert.ToInt32(rating) == Convert.ToInt32(rl._rating))
                        {
                            //message.To.Add(new System.Net.Mail.MailAddress(rl._mailto));
                            recipient = rl._mailto + "," + recipient;
                        }
                    }
                    else if (rl._ratingtype == "Greater than and equal to")
                    {
                        if (Convert.ToInt32(rating) >= Convert.ToInt32(rl._rating))
                        {
                            //message.To.Add(new System.Net.Mail.MailAddress(rl._mailto));
                            recipient = rl._mailto + "," + recipient;
                        }
                    }
                    else if (rl._ratingtype == "Less than and equal to")
                    {
                        if (Convert.ToInt32(rating) <= Convert.ToInt32(rl._rating))
                        {
                            //message.To.Add(new System.Net.Mail.MailAddress(rl._mailto));
                            recipient = rl._mailto + "," + recipient;
                        }
                    }
                }
                recipient = recipient.TrimEnd(',');
                message.To.Add(new System.Net.Mail.MailAddress(recipient));

推荐答案

邮件对象的收件人"字段实际上是收件人的集合.无需尝试将所有收件人串联为一个字符串，只需将每个收件人单独添加即可，并且只要您的rl._mailto地址均有效，它就可以正常工作.

The "To" field of the mail object is actually a collection of recipients. Instead of trying to concatenate all the recipients into 1 string, just add each one individually and it should work provided each of your rl._mailto addresses are valid.
