web service serialisation

[azadur]

hi all,
hope you can help.
im writing some webservice to retireve data from a db(sql server)
ive create some objects to encapsulate the data.
the classes have been set as serializable.
from my webservice, i can get a single object or a collection of objects back.
the problem i am having is that the service wont return back collections of object within a class.

e.g

class item
property a
property b
end class

class items

property name

property items as item()

end class

in such a scenario where the items class contains a collection of item, i only get back the property name for example but not the collection.

they are all declared as public
i tried the items with readonly and read/write.
any pointer would be greatly appreciated.

many thanks in advance.

I don't understand your example, or why serialization has anything to do with it. If your method returns a collection of objects withing some kind of collection class why can you not access those multiple objects?

sorry, i was trying to keep it short.
class1 has some public properties
class2 inherits collectionbase. it has 2 public methods, add, remove to keep a collection of class1 objects

i have a class3 which has come properties. it also has a property which is class2.
when i return class3 from the ws, it only serialises the public properties in class3. it does ode serialise the collection of class2 objects
i.e


public property items as class2

it is a serialisation problem, because i am looking for deep serialisation.

so:

class1
public name

class2:collectionbase
public add(o as class1)

class3
public value
public items as class2


my ws returns

<value/>
<value/>


i would like(assume 1 object in the items)

<value/>
<items>
<name />
<items>
<value/>

Maybe you should post some code because I still have no idea what you are talking about.
