我们的应用程序发送电子邮件进行确认等。以前使用SMTP。我们设置了链接资源的邮件，它显示的图像内联刚刚好。
现在有一个客户端切换到了Azure，所以我添加了通过Azure发送电子邮件的代码。邮件被发送和接收，但内嵌图像不显示在正文中。它作为一个附件在那里，我不想看到它。
这是我的SendMailPostRequestBody（为了阅读而序列化）：

}我收到了电子邮件，它有三个附件。其中之一就是形象。我希望这一个不是可见的附件时，显示在体内内联。contentBytes不显示它，但其中有一个base64字符串。我可以在outlook中打开邮件中的附件。
为什么图像没有显示在身体里？

我想明白了
显然，您必须将“ContentId”添加到附件的AdditionalData字典中。
因此，对于用于显示内联图像的附件，addtionaldata字典应该如下所示：
然后oulook将能够显示图像。
