Using C# .NET 2.0, I have a composite data class that does have the
[Serializable] attribute on it. I am creating an
XMLSerializer class and passing that into the constructor:
XmlSerializer serializer = new XmlSerializer(typeof(DataClass));
I am getting an exception saying:
There was an error reflecting type.
Inside the data class there is another composite object. Does this also need to have the
[Serializable] attribute, or by having it on the top object, does it recursively apply it to all objects inside?
Look at the inner exception that you are getting. It will tell you which field/property it is having trouble serializing.
You can exclude fields/properties from xml serialization by decorating them with the
I don't think that
XmlSerializer uses the
[Serializable] attribute, so I doubt that is the problem.
Remember that serialized classes must have default (i.e. parameterless) constructors. If you have no constructor at all, that's fine; but if you have a constructor with a parameter, you'll need to add the default one too.
