asp.net 邮件添加 ReplyTo

Question

如何在 ReplayTo 字段中添加与发件人不同的电子邮件地址？似乎 MailMessage.ReplyTo 已被弃用，因此我尝试使用 ReplyToList 代替。

但是它告诉我

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

这是迄今为止我的代码:

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

您无法将其设置为全新的MailAddressCollection，但您可以直接添加到现有的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);
