Non-Serializable and MarshalByRef Objects

Hi All,

I'm working in an environment where Serialization is used.  While I basically understand why one would use Serialization, I don't really understand the programming specifics behind it.  I occasionally receive the following error as I build my pages, and don't understand what parts of my code cause it:

"Unable to serialize the session state. Please note that non-serializable objects or MarshalByRef objects are not permitted when session state mode is 'StateServer' or 'SQLServer'."

These errors SEEM to be related to my use of Session vatiables -- though I'm really not sure.

Does anyone out there have any idea of general guidelines to follow when programming in an environment where Serialization is used in order to avoid such errors.  Perhaps a link to an article?

Thanks much,

K

Hi K,

It is related to your session variables, it is easily solved, if you have a session vaiable that is a clas you created, just add the
serializable attibute to at the beginning of the class declaration

<Serializable()> Public Class Yourclassname

This adds code behind the scenes to your class be serialized and thus usable with session state  'StateServer' or 'SQLServer'
the alternative, which doesn't seem to be an option here, is to change the session state to InProc, then you don't have to worry about serialization :)

as for articles go to google and search asp.net and serialization there are lot of articles, but here are a couple to get you started..

Thanks NotaClue --  This info was exactly what I was looking for.  I wish I had the option to change the session state to InProc, but the powers that be lay down such laws:-)

Regards,

K
