string? ContentId { get; set; }Property Value
StringThe content identifier.
Remarks
The Content-Id header is used for uniquely identifying a particular entity and uses the same syntax as the Message-Id header on MIME messages.
Setting a Content-Id allows other MimePart objects within the same multipart/related container to reference this part by its unique identifier, typically by using a "cid:" URI in an HTML-formatted message body. This can be useful, for example, when the HTML-formatted message body needs to reference image attachments.
Note
It is recommended that GenerateMessageId or
GenerateMessageId(String) be used to generate a valid
Content-Id value.
Exceptions
| ObjectDisposedException | The IMimeEntity has been disposed. |
