How to Save/Store non serializable objects
-
While coding for a MS Exchange email client I came up with a peculiar problem. I am using Exchange Web Service Managed API to access the exchange mail server and getting the mail messages. The problems occur when I try to store the message object into the disk. While serializing the object it is throwing a SerializationException saying that - "Type 'Microsoft.Exchange.WebServices.Data.EmailMessage' in Assembly 'Microsoft.Exchange.WebServices, Version=14.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' is not marked as serializable.". One thing is not clear to me, if the object is not serializable then how come it is being transferred through the web service? Secondly, do any one have any idea on how to store this non serializable object into disk. I am in a dire need. Thanks and regards,

Probably, the
EmailMessageisn't the thing being passed across the wire.Anindya Chatterjee wrote:

Two options (but I don't know the details of
EMailMessage, so take with a pinch of salt: a) Make a serializeable object and write a converter to convert bewteen this andEmailMessageb) Hand-serialize the object from its properties etc. That said, the object you have probably contains alot of information needed at runtime and have security implications (which are probably two of the reasons why the object is not marked as serializable). Given there are lots of readonly properties, you won't be able to deserializeEMailMessage, but if you are just interested in storing and retrieving the contents you should be fine.Dalek Dave: There are many words that some find offensive, Homosexuality, Alcoholism, Religion, Visual Basic, Manchester United, Butter.

Does that EmailMessage not have a ToString() and a FromString() method? Since emails are transported as plain ASCII, that should do the thing. Otherwise, create a serializable object containing all the relevant properties, i.e. message body, to, cc, subject, etc. and serialize that.
