Hello experts,

I have a class that starts as follows;-

namespace ShoppingCartEngine
{
    /// <summary>
    /// Summary description for CartEngine
    /// </summary>
    [Serializable]<-------------------------------------------------PLEASE NOTE THIS LINE
    public class CartEngine
    {
    }

}


Now when I try to load my XML File like so;-
 //Load CartXML
            oXmlDoc = new XmlDocument();
            try
            {
                oXmlDoc.Load(HttpContext.Current.Server.MapPath("XMLFile.xml"));
            }
            catch (Exception ex)
            {
                HttpContext.Current.Response.Write("<br>Error: <br>" + ex.Message);
            }

I get the following error;-
Type 'System.Xml.XmlDocument' in Assembly 'System.Xml, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Runtime.Serialization.SerializationException: Type 'System.Xml.XmlDocument' in Assembly 'System.Xml, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.


What does this error mean?
How do I fix it.

Thank you
