serializable

I want to use one or two small xml files to persist some very basic
applications settings and it seems that using xml files will probably be a
better solution than my old way of using the registry.

I am not well versed in XML.  I spent a few hours looking through the Help
system to learn more about reading and writing XML stuff - it seems that NET
does a very solid job supporting such functionality.  Anyway, when reviewing
the XmlWriter and XmlReader classes, I stumbled on the 'serializable'
attribute - which will make some of this persistence even easier.

The problem I'm having is marking some things non-serializable and the Help
system isn't helping me out here.

In one main object I want to serialize, I have a field for an application
password.  The object has properties to return this password in an encrypted
form and an unencrypted form - although there is only one private variable
holding the password.  So if I'm not mistaken, if I want to just mark the
class serializable, then I need to create private variables for the
encrypted password and the unencrypted password and mark the encrypted one
as [NonSerializable()].  Is this correct?  Is there a 'better' way (I
haven't really looked at implementing ISerializable yet).
