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.
