推荐答案
要创建已读回执，您需要在MailMessage中添加标题，例如;
To create a read receipt you need to add a header to the MailMessage like;
MailMessage mail = new MailMessage();
mail.Headers.Add("Disposition-Notification-To", "someaddress@mydomain.com");
只需记住，用户可能不同意发送已读回执，因此您无能为力.
Just remember that a user may not agree to send the read receipt, and there is nothing you can do to force it.
很难准确地说出这些代码，但请尝试...
Hard to say exactly without seeing the code, but try...
objSendMail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess;
那应该做.
That should do it.
