查看最后一个链接。这是您指定MIME类型的位置，例如image / jpeg或image / png。请参阅： http://www.iana.org/assignments/media-types/media-types .xhtml [ ^ ]。

Please see:

https://msdn.microsoft.com/en-us/library/system.net.mail.attachmentbase.contenttype%28v=vs.110%29.aspx[^].

See the last link. This is where you specify the MIME type, such as "image/jpeg" or "image/png". Please see: http://www.iana.org/assignments/media-types/media-types.xhtml[^].

As I can see, this is all you need.
