Serialize form

Hi,
I have a problem about serialize the form controls. I wrote a test program
to test serialize a from but fail (->An unhandled exception of type
'System.Runtime.Serialization.SerializationException' occurred in
mscorlib.dll) . Thx in advance. Here is the part of the code:

I don't know what the specific error means, but I would recommend against
trying to serialize something as complex as a form. The reason being that
the serializing engine will walk through the member variables and when you
try to serialize objects that maybe were not meant to be serialized (i.e. a
Button), you risk having conflicts. All nested object must also be
serializable for this to work.

What is the purpose for trying to serialize a Form object? Is it so that
you can easily recreate the form's state later? You might want to consider
creating a data structure that holds all the form state information which
you could then serialize.

Hi Peter,

Thx for reply. Actually, i want to serialize a static collectionbase class
that store few customized buttons which have location, bitmap, and some
controls properties. These button was added to collectionbase class by the
users in runtime. Can i do it in that way? Thx again.

I would suggest, you write your own serialization routine for your
customized button and then, call that routine for all the form's children
from the form. The idea here is, do not depend on the Serializers for UI
elements. You will run into issues when any of these controls have
references to some other object that is not serializable, (or cicular
references - I'm not sure about this part, though).

It's easy to write a simple serializer. I would recommend using XML, to
help you debug easier. Using Reflection, gather all the properties of the
button you are interested in and then, write out xml snippets for each.
