问题
Otherwise than pointed out in this post I would like to act just before an XmlSerializer starts deserializing (not when finished deserializing)
Background: I have a baseClass that implements INotifyPropertyChanged. This BaseClass is stored as xml in a database and when retrieved deserialized into an object instance. The deserialization executes the setters of this class where my ChangeNotification takes place. On a centralised handler for the changenotification I set the status of the object and keep track of stacks for undoing changes. Apparently I don't want these to be trigerred during deserialization.
Any ideas would be very welcome!
回答1:
XmlSerializer doesn't support serialization callbacks. One option is to use IXmlSerializable, but that is lots of work. In some simple cases DataContractSerializer may be a viable option; it supports the cllbacks, but it does not support as many XML scenarios (most notably: no attributes).
You may be out of luck, in which case consider a separate DTO and domain type. For example, you could deserialize into FooDto, then copy the values into a Foo, manually telling it that this is via serialization.

As commented @ Marc's solution. The most pragmatic way right now (I'm developing a proof of concept for a big chunk of complex functionality) is to default the object after it has been deserialized with a simple public void. In this method I can empty the undo stack and set the status of the object to unchanged.
If I come up with some better ideas I'll post them here.
