我有多部分/混合體的郵件包含嵌套的多部分/相關部分與Html部分和相關的圖像部分。有沒有辦法將這些電子郵件構建爲System.Net.Mail的MailMessage實例？如何使用system.net.mail發送非替代性的多個部分
這不是一個備用查詢問題。
- multipart/mixed 1.1。多部分/相關 1.1.1。 text/html 1.1.2。圖片/ gif 1.2。多部分/相關 1.2.1。 text/html 1.2.2。 image/gif
1.1.1與1.1.2相關。但它與1.2.2無關。 1.1.1和1.2.1是獨立的html實體。
我在下面粘貼了一條示例消息。

我知道lumisoft的庫。我看過像MimeKit這樣的其他開源軟件。由於我的要求，我不得不開發自己的解析器。如果我能解決上述問題，那將是完美的。 –
我看不到MailMessage將允許解析或構建複雜的消息，所以你不能這樣做。爲什麼你需要這麼拼命MailMessage？那你爲什麼不做自己的課？如果您需要SmtpClient類，那麼這是一個問題，但如果使用一些免費的可用庫，則您可以編寫自己的SMTP客戶端。 – user2959922
