这只是具有适当的内容类型：text / html，当然还有HTML上下文本身。你的邮件正文不是HTML，但我希望你知道怎么写。
（更准确地说，在MailMessage术语，表示为ContentType.MediaType属性;请参阅下面的最后一个链接。）
这很简单：属性System.Net.Mail.MailMessage.IsBodyHtml可以解决问题：
https://msdn.microsoft.com/en-us/library/system.net。 mail.mailmessage％28v = vs.110％29.aspx [ ^ ]。
如果你想只做一部分你的邮件HTML，它会更棘手。您可以创建多部分邮件消息。部件扮演具有不同内容处置值的附件角色，例如在呈现时嵌入在邮件文本中，或者可下载的附件，或替代视图或链接资源。然后每个部分都可以有自己的内容类型;一个可以是HTML另一个是位图。有关详细信息，另请参阅：
https://msdn.microsoft.com/en-us/library/system.net.mail.attachment%28v=vs.110%29.aspx [ ^ ] ，
https ：//msdn.microsoft.com/en-us/library/system.net.mail.attachmentbase%28v=vs.110%29.aspx [ ^ ]，
https：// msdn .microsoft.com / zh-cn / library / system.net.mail.attachmentbase.contenttype％28v = vs.110％29.aspx [ ^ ]，
https://msdn.microsoft.com /en-us/library/system.net.mime.contenttype.mediatype%28v=vs.110%29.aspx [ ^ ]。-SA
This just a matter of having appropriateContent-type: "text/html", and of course HTML context itself. Your mail body is not HTML, but I hope you know how to write it.
(More exactly, inMailMessageterminology, this is expressed asContentType.MediaTypeproperty; please see the last link below.)
This is easy: the propertySystem.Net.Mail.MailMessage.IsBodyHtmldoes the trick:
https://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage%28v=vs.110%29.aspx[^].
If you want to make only part of your mail HTML, it would be more tricky. You can create multi-part mail message. Parts plays the roles of attachments with differentcontent-dispositionvalues, such as embedded in the mail text when rendered, or downloadable attachments, or alternative views or linked resource. Then each part could have its own content type; one can be HTML another one a bitmap. For further information, see also:
