邮件正文：＆amp;变成（R）

Question

我们有一个网站，我们会在新客户注册时向我们的客户发送自动生成的邮件。我们的邮件有一个看起来像

但是当我们的德国客户收到邮件时，他会收到以下激活链接，您会注意到＆amp;字符更改为®

任何人都可以告诉我为什么＆amp;角色变为®？
如何解决这类问题？

Answer 1

尝试使用CreateAlternateViewFromString属性，这是示例代码

MailMessage emailmsg = new MailMessage("from@address.co.za", "to@address.co.za")
emailmsg.Subject = "Subject";
emailmsg.IsBodyHtml = false;
emailmsg.ReplyToList.Add("from@address.co.za");
emailmsg.BodyEncoding = System.Text.Encoding.UTF8;
emailmsg.HeadersEncoding = System.Text.Encoding.UTF8;
emailmsg.SubjectEncoding = System.Text.Encoding.UTF8;
emailmsg.Body = null;

var plainView = AlternateView.CreateAlternateViewFromString(EmailBody, emailmsg.BodyEncoding, "text/plain");
plainView.TransferEncoding = TransferEncoding.SevenBit;
emailmsg.AlternateViews.Add(plainView);

SmtpClient sSmtp = new SmtpClient();
sSmtp.Send(emailmsg);
