If I am returning a read only collection
public class MyReadOnlyCollection : ReadOnlyListBase<MyReadOnlyCollection, MyReadOnly>
via a method in a web service, and what to access and use the collection, is it possible?
This is my web service method:
[
OperationContract]public MyReadOnlyCollection MyCollectyion()
When I add a web reference, it cannot seem to see the collection , but returns the readonly object as a reference that I can use. Ideally I want to loop around the Read Only collection and access each read only object on the client.
It is not possible to return a CSLA business object directly as the result of a web service.
It is also not desirable to do this. It is just a bad idea, and so I have never tried to make it work. No sense enabling something no one should ever do :)
There are numerous threads on this topic in the forum. But there's also a complete chapter in the Expert Business Objects book (chapter 11 in 2005 and chapter 21 in 2008) that discusses the issues and solutions around XML service interfaces.
Thanks Rocky, I took a look at the chapter, so you would advice wrapping the csla business objects with a new abstraction class layer, will look to do this instead. This is what I have done previously, but wondered if there was an easier (less time consuming) method.
Thanks.
