XmlSerializer and IEnumerable

I'm trying to serialize a class with XmlSerializer. This class implements
the IEnumerable interface. I implemented the IEnumerable interface for
reasons other than Xml serialization.

However I find that the XmlSerializer, because I have an IEnumerable
interface on this class, wants to ignore the public properties of this class
and simply serialize an array of objects.

I wand XmlSerializer to ignore the IEnumerable interface that I have
implemented on this class. How do I do that?

Have you marked your properties with [XmlAttribute] and/or [XmlElement]?
Those are "hints" to the deserializer/serializer as to what/how do convert.
I wrote a custom deserializer that can handle abstract/concrete types and
had to use those attributes + write a few of my own extensively.
De/serialization can automatically handle some objects, but when you start
getting more complex objects, those attributes are indispensible.

Keith,

Yes I am using XmlAttribute and XmlElement attributes.

If a class implements IEnumerable however, you cannot add XML attributes to
it.

For example

[XmlType("Collection")]
public class joaCollection : joaItem, IEnumerable
{
//...

}

Results in the following error...

System.InvalidOperationException: There was an error reflecting type
'DotnetBench.joaCollection'. ---> System.InvalidOperationException: XML
attributes may not be specified for the type DotnetBench.joaCollection.

I also found a reference that says that this behavoir is "by design". Whose
idiotic design is this?

I am very unhappy about this. The reason I want to use IEnumerable is so my
collection can be used in foreach statements. However it appears that if I
want to have a few XML serialized properties in my class I will need to
abandon IEnumerable!

Thanks for the help,
Bob Rundle

Keith,

I'm curious about your custom deserializer. I've finally given up on
XmlSerialize() and will have to write my own serialization. I'm planning to
add a Serialize() method to each of my classes to (de)serialize the
individal class. Is this the proper approach or is there another pattern to
follow?

Bob Rundle
