Hi
I wish to use ASP.Net Session Store to store a value to session. The value or object if you prefer is marked as serializable in order to be placed within the store.

Unfortunately, when running the code I get an unhandled exception error being displayed to the screen. The code itself does not fail at any point in debug. The actual error message in full is "An unhandled exception occurred 'Type 'System.Xml.XmlDocument' in Assembley 'System.Xml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable"

The problem has been traced back to some properties that are xml documents, which due to session store being binary serialization is not compatible with xml documents. I have overcome the problem by making the xml document a string and then turning back again to xml afterwards.

My question is this, is there a better way of doing this? Surely, I don't need to go through all of this save something to session?

Hi, you can create a class as your return variable that will contain the Xml document, then add a serializable declaration.

C#

[Serializable()]
public class XmlReturnClass  {
   ///Declare Xml here
   ///....
   ///....
}

Good luck!
