郵件不會與多個工作地址

Question

可能重複：
Unable to send an email to multiple addresses/recipients using C#

我用下面的代碼來發送郵件的腳本任務

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); 

據當我使用MailToEmail作爲「myaddress@myMail.com」，即一個電子郵件地址時，正常工作

但這不發送任何郵件（也忽略了最低失敗），當我有多個ADRESS到列表

例如：「MyAdress@MyMail.com; MySecondAddress@MyMail.com」

如何解決此問題？

編輯新代碼

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); 

Answer 1

你未顯示你究竟是如何添加收件人，但添加多個收件人你添加到「收件人」：

MailMessage message = new MailMessage(); 
message.To.Add("sillyjoe@stackoverflow.com"); 

「收件人」是MailAddresses的集合，請確保將它添加到該收藏夾中n並且不試圖將電子郵件地址全部連接成一個MailAddress對象。

Answer 2

要指定多個地址，您需要使用To屬性是一個MailAddressCollection

message.To.Add("one@example.com, one@example.com")); 
message.To.Add("two@example.com, two@example.com")); 

Answer 3

Accoring到MSDN: MailMessage Class 「到」 財產MailAddresses

所以你只需要做的事情的集合像

mailmsg.To.Add(new System.Net.Mail.MailAddress(MailToEmail, MailToEmail)); 
mailmsg.To.Add(new System.Net.Mail.MailAddress(MailToEmail2, MailToEmail2)) 

或在foreach循環

//get email addresses into a collection called emailAdds 
foreach (var emailAdd in emailAdds) 
{ 
    mailmsg.To.Add(new System.Net.Mail.MailAddress(emailAdd, emailAdd)); 
}
