It is impossible to directly deserialize into instances of Device-Request. Jon Davis9-Feb-10 6:39 Jon Davis9-Feb-10 6:39 Instead of instantiating the serializer with the known type, just instantiate the serializer with the target type? Just what I was looking for. I can specify all the relevant "extratypes" to the serializer but I can't tell it about the namespace (even if I put this in all the attributes it makes no difference).Has

The only fly in the ointment was that I now had an extra public property in ViewInfo that I didn't really want (it had to be public, otherwise XmlSerializer would ignore Using the XmlInclude attribute (as recommended in the exception description) does work (basically, it manually adds a Type to the list discovered during the generation phase), but it means that I Does every data type just boil down to nodes with pointers?

Privacy statement Help us improve MSDN. From MSFT, To increase performance, the XML serialization infrastructure dynamically generates assemblies to serialize and deserialize specified types. A promising option was the Type property on the XmlElement attribute that allows a derived type to be specified.

Deserializing into the abstract type will not work because the xml serilization in animalStr contains more than an Animal, it contains either Cat or Dog.

Differential high voltage measurement using a transformer The Ooh-Aah Cryptic Maze Is an animated corpse with a weapon overpowered? What we are doing here is telling the serializer that if it should come across a property or method called "Parameters" in a ViewInfo Type, then pretend it had an XmlElement Sign In·ViewThread·Permalink Great Code, but you should just make the serializer generic...

The problem is i'm using SOAP::WSDL so i'm not actually writing the XML myself, i'm just creating a Perl hash/array and SOAP::WSDL converts it into the XML. Because DashboardParamsSerializer implements IXmlSerializable, the serializer calls its WriteXml method, and this gives us the opportunity to add an attribute into the current element and store the actual Type into it. That is what is causing the exception you see.

Is there a way to make the serializer pick up what is required off the abstract class or am I going completely the wrong way about this? However, I also need to be able to deserialize the same XML structure back. What are the benefits of an oral exam? So in this case introCommand should contain an instance of PlayElement.

The DashboardParamsSerializer can be a simple wrapper for the DashboardParams like in the following post: http://rboxman.spaces.live.com/blog Sign In·ViewThread·Permalink Multiple namespaces problem? If XmlSerializer was simply casting to the new type rather than explicitly checking that it was a derived type, then the implicit overload methods would silently convert between DashboardParamsSerializer and DashboardParams I suggest further research into factory patterns which seems to be what you are trying to implement here. 26/Sep/2006 13:36 PM said: Thanks for the article. The serializer comes along, sees that XmlParameters is a read/write property of type DashboardParamsSerializer, and asks for its value.

The only thing I have changed from the example in the before mentioned thread is the class names. It is a base class intended to be overridden by any number of classes that hold parameter information. Because the assembly containing Elephant references the assembly containing Animal, you can't add the XmlInclude attribute on Animal, because that would also require a reference in the other direction, and this more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed
