XML Serialization

[RJN]

Hi

I'm using XML Serialization for serializing an object. I read a set of
records from the database and populate the members of the object if the
value is not null. eg., I have an Employee object which has its members
Id,name and address. If the Id is not null then I will populate its
value from that I got from the databse. When I serialize the object , I
find that xml structure will always have the Id column either with the
actual value or with value 0 if the value is Null in the databse.
<employees>
<employee><Id>111</Id><name>aaa</name></employee>
<employee><Id>0</Id></name></employee>
</employees>

My feeling is this is the default behaviour of xml serializer for data
types int, boolean and date and will have a value 0,0001-01-01 and false
as default values respectively.

I cannot set the property <XmlElement(IsNullable:=True)> for value
types. Is there any way where I can avoid serializing types of int,date
and boolean when they have null values in the database.

Regards

RJN

Why don't you use dataSet, put info into dataSet, use DataSet.WriteXml will meet your requirment.

I can't use dataset as there is a hierarchy within the objects. i.e.,
Employee will have a list of addresses etc..
something like this.

<Employee>
<Id></Id>
<Addresses>
<Address></Address>
</Addresses>
</Employee>

So I construct the object graph and then serialize the object
