Hello Martin,

I tried your program in Windows Console mode and it works, but I=92m
afraid it does not work for my more complicated class object being de-
serialized.

If you have any ideas why please post.  Please don=92t spend too much
time as you have helped enough.

I personally don=92t care that I cannot get my program to work like
yours, even though it would be an improvement, since my old, long way
of checking each element, and de-serialising that element, though more
time consuming, does work for me.  However, it would be nice to
deserialize the entire object =93at once=94, like is done in binary
deserialization.

//Here is the relevant code for deserializing.  It does not work,
since the condition xr.Name =3D=3D =93DecoratedPerson=94 is never reached.

This code fragment appears to be failing: =93if(xr.NodeType =3D=3D
XmlNodeType.Element && xr.Name =3D=3D "DecoratedPerson")=94

When I run the Debugger, the condition xr.Name =3D=3D =93DecoratedPerson=94=
 is
never reached, because xr.Name is:  =93FiRstName=94 or =93theEmaiL=94 or =
=93Age=94
or =93UserId=94, etc. It is never "=3D=3DDecoratedPerson"

Consequently, the List is never populated and always has a count of
zero, being empty.

Thank you for your help.
