Hi Sonal,

Can you post the method signature and any custom types you are using?

Thank you

I am implementing remoting.. making a remotable object in a facade class to access the getDocumentByID method of the document engine class. the metoh definition goes like :

public Document GetDocumentByID(int documentID, DocumentType documentType) and

public Document GetDocumentByID(int documentID)

(overloaded methods)

Have you marked DocumentType with the [Serializable] attribute?

Thank you

yes.. i have marked document type class as serializable.. can this error come if certain types defined in document type class are unserializable?

Yes, all types have to be serializable.

ok.. can u please let me know what all types(or objects) are non-serializable in .net. and if we mark an object as non serializable.. why do we do that? thanks for all the help

Any class without the class attribute [Serializable] is not serializable.

I.e. any of your classes should include this attribute.

Is DocumentType defined in a separate assembly? Are you hosting in IIS? If so, can you check that the web.config has a reference to the assembly containing DocumentType?

Thank you
