Is there a C# library that enables me to convert my C# object to/from JSON? My class object will contain intrinsic types, XmlDocument, and ArrayList (which will hold instances of other classes - no relation to this class).

Ajax.NET Pro is the most promising but it appears to have a bug with XmlDocument objects. C#'s XmlSerializer (the preliminary step I would alternatively use to convert my object to JSON) has problems with the ArrayList containing other class objects.

I am looking for a fully working solution for a C# object (.NET framework v1.1) to/from JSON conversion.

Thanks for any pointers.
