如果附件是邮件，如何访问附件数据 [英] How to access attachment data if attachment is mail

问题描述

全部，

我以下列方式以编程方式获取附件数据： -

Microsoft.Office.Interop。 Outlook.Attachment attachment = objMail.Attachments [attachmentIndex];

if（attachment.DisplayName.Equals（" Test"））

{  ;

    const string PR_ATTACH_DATA =" http://schemas.microsoft.com/mapi/proptag/0x37010102" ;;

    byte [] attachmentData = attachment.PropertyAccessor.GetProperty（PR_ATTACH_DATA）;

}

现在我的代码工作正常，如果附件是文本文件或图像文件。但是如果附件本身就是一个邮件，它会抛出属性未知或无法找到的异常。

请建议在哪种情况下/附件类型，此属性"http：/ /schemas.microsoft.com/mapi/proptag/0x37010102"将无法工作，在这种情况下，什么是替换属性/方法来获取字节数组中的附件数据？

谢谢

HI全部，

正如Dmitry所回答的那样，可以使用IAttach.OpenProperty来实现。有人可以提供示例，如何调用此函数在C＃中打开任何嵌入的附件。

谢谢

HI All,

I am programmatically getting the attachment data in following way :--

Microsoft.Office.Interop.Outlook.Attachment attachment = objMail.Attachments[attachmentIndex];

if (attachment.DisplayName.Equals("Test"))

{ 

   const string PR_ATTACH_DATA = "http://schemas.microsoft.com/mapi/proptag/0x37010102";

    byte[] attachmentData = attachment.PropertyAccessor.GetProperty(PR_ATTACH_DATA);

}

Now my code is working fine if attachment is text file or image file. But if attachment is itself a mail, it throws the exception that property is unknown or can not be found.

Please suggest in which cases / type of attachments, this property "http://schemas.microsoft.com/mapi/proptag/0x37010102" will not work and in those case what would be alternative property / method to get the attachment data in byte array ?

Thanks

Devendra

HI All,

As replied by Dmitry, it can be achieved using IAttach.OpenProperty. Can someone please provide the example, how can I call this function to open any embedded attachment in C#.

Thanks
