几天前，我访问了博客，其中说 System.Net.Mail.SmtpClient 已过时，开源库 MailKit 和 MimeKit 替换。

Few days back I visited a blog that said System.Net.Mail.SmtpClient is obsolete and an open source library MailKit and MimeKit is replacing it.

我可以看到 docs ，但在参考代码并在库中。是不是已经过时了？

I can see docs for that but not finding the same in reference code and in library. Is it obsolete or not?

[System.Obsolete("SmtpClient and its network of types are poorly designed, we strongly recommend you use github/jstedfast/MailKit and github/jstedfast/MimeKit instead")] public class SmtpClient : IDisposable

推荐答案

正如Liam指出的那样，由于文档中的错误，这已经过时了。 是System.Net.Mail .smtpClient在4.7中过时了？

As Liam pointed out, this is obsolete due to a bug in documentation. Is System.Net.Mail.SmtpClient obsolete in 4.7?
