How do I copy the content of mime emails?

推荐答案

MIME编码的电子邮件不使用 TIdMessage.Body 属性.他们改用 TIdMessage.MessageParts 属性，其中文本MIME部分存储为 TIdText 对象，附件存储为源自 TIdAttachment 的对象.您必须查看 TIdMessage.ContentType 属性，以了解您使用的是HTML电子邮件还是MIME电子邮件.即使那样，HTML电子邮件实际上仍可能是MIME编码的，因为它们通常包括非HTML电子邮件阅读器的替代纯文本MIME部分.您可以遍历 TIdMessage.MessageParts ，查找 ContentType 为HTML的 TIdText 对象，然后复制 TIdText.Body 内容添加到您的TMemo中.

MIME-encoded emails do not use the TIdMessage.Body property. They use the TIdMessage.MessageParts property instead, where textual MIME parts are stored as TIdText objects and attachments are stored as TIdAttachment-derived objects. You have to look at the TIdMessage.ContentType property to know whether you are working with an HTML email or a MIME email. Even then, chances are that HTML emails are actually MIME encoded, as they usually include an alternative plain-text MIME part for non-HTML email readers. You can loop through the TIdMessage.MessageParts looking for a TIdText object whose ContentType is HTML, then copy the TIdText.Body content into your TMemo.
