Serialization of object tree

[Dim]

Hi!

Kinda newbie to .NET nad got following question:
Serializing objects in C#:

I have a complex object that contains lots of data and other object
including GraphicsPath, Point, Rectangle etc.. mostly
from System.Drawing, System.Windows.Forms.

When my object is constructed completelly and all graphics have been created
(btw my object inherits Panel class)
i want to be able to serialize whole bunch starting with my object and down
to the last variable in objects within that i have set.

I tried to serialize it simply by passing it to IFormatter and adding an
open file stream, but i get an exception telling
me that Panel class is not marked as Serializable. Ok i accepted this and
remade object so that only objects within should serialize. But not
enought... even GraphicsPath is apparently not serializable.
So i can't serialize nothing but simple classes with just some variables????
How can i serialize the whole tree.. cause its a big tree and saving only
primitives and reconstructing it later is way too much work.

Thanx!!!

Ok thax man :-) I will look closer at your solution!!

I had the same problem and eventually did it the hard way ;)
I wrote a couple of wrapper classes (one for each non-
serializable type), where I could record all revelant properties.
I serialized these wrappers instead.

I also estabished a small interface to turn oryginal types into
wrappers and back (during serialization and deserialization).
I used a IDeserializationCallback interface and Reflection
(since most of the work went in the root class of my class
hierarchy).

Unfortunately I had to limit amount of types supported, since
was unable to recreate certain types on the basis of their
properties. If you find a better solution, don't forget to let
me know ;)

HTH,
