asp.net mail add ReplyTo

Question

我如何添加一個不同的電子郵件，然後在ReplayTo字段發件人？ 似乎MailMessage.ReplyTo已被棄用，所以我試圖用ReplyToList代替。

但它告訴我，

Property or indexer 'System.Net.Mail.MailMessage.ReplyToList' cannot be assigned to -- it is read only 

這裏是我到目前爲止的代碼：

var reply = new MailAddressCollection(); 
reply.Add("test@test.com"); 
MailMessage mail = new MailMessage(senderEmail,usr.Email,"subject","message"); 
mail.ReplyToList = reply; 
var smtp = new SmtpClient(); 
smtp.Send(mail); 

Answer 1

不能設置它提升到一個全新MailAddressCollection，但是你可以直接添加到現有MailAddressCollection，如下所示：

MailMessage mail = new MailMessage(senderEmail,usr.Email,"subject","message"); 
mail.ReplyToList.Add("test@test.com"); 
var smtp = new SmtpClient(); 
smtp.Send(mail); 

Answer 2

S因斯的ReplyToList是一個只讀屬性，你可以做的唯一途徑是：

mail.ReplyToList.Add(new MailAddress("abc@xyz.com")); 
mail.ReplyToList.Add(new MailAddress("def@abc.com"));
