如何在c＃中发送多部分MIME消息？ [英] How to send multi-part MIME messages in c#?

问题描述

我想发送带有HTML组件的多部分MIME消息以及电子邮件客户端无法处理HTML的人的纯文本组件。 System.Net.Mail.MailMessage 类似乎不支持此功能。你如何做？

I want to send multi-part MIME messages with an HTML component plus a plain text component for people whose email clients can't handle HTML. The System.Net.Mail.MailMessage class doesn't appear to support this. How do you do it?

推荐答案

D'哦，这真的很简单...但我会在这里离开答案对于任何像我这样的人来说，在Google搜索之前找到答案...：）

D'oh, this is really simple... but I'll leave the answer here for anyone who, like me, came looking on SO for the answer before Googling... :)

信用到本文。

使用 AlternateViews ，像这样：

//create the mail message
var mail = new MailMessage();

//set the addresses
mail.From = new MailAddress("[e-mail]");
mail.To.Add("[e-mail]");

//set the content
mail.Subject = "This is an email";

//first we create the Plain Text part
var plainView = AlternateView.CreateAlternateViewFromString("This is my plain text content, viewable by those clients that don't support html", null, "text/plain");
//then we create the Html part
var htmlView = AlternateView.CreateAlternateViewFromString("<b>this is bold text, and viewable by those mail clients that support html</b>", null, "text/html");
mail.AlternateViews.Add(plainView);
mail.AlternateViews.Add(htmlView);

//send the message
var smtp = new SmtpClient("127.0.0.1"); //specify the mail server address
smtp.Send(mail);
