Serialization of Inherited Class

[Michael Slattery]

Hello... although I've found several posts in reguards to this topic, I don't
seem to understand the solution...

When I derive a class from my base class and then serialize using
XMLSerializer, I do not see the properties of the base class.

Project 1 - Class Library

Public Class nameBase
{
Public string name;
}

Project 2 - WinApp

Public Class names : nameBase
{
Public string location;
}

List<namestoSer ialize = new List<names>();
List.add(...)

XmlSerializer mySerializer = new XmlSerializer(t ypeof(List<name s>));
StreamWriter myWriter = new StreamWriter("m yFileName.xml") ;
mySerializer.Se rialize(myWrite r, toSerialize);
myWriter.Close( );

Please help me understand why I don't see the base class name property?

I've tried several XmlInclude(type of(...)) attributes.

Walter,

I was unable to download the project you attached... can you post the code
please.

Thanks,
Mike Slattery

Hi,

I've tested using a simple solution and it works correctly. I'll attach it
here for your reference. (You may have to use Outlook Express to download

A sample serialized xml file:

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfDeriv ed xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http ://www.w3.org/2001/XMLSchema">
<Derived>
<Name>base name</Name>
<Location>url </Location>
</Derived>
</ArrayOfDerived>

Please tell me whether or not my test project works or not. Thanks.

Hi Mike,

I'm assuming that your question is not being able to serialize the
properties inherited from base class, right?

The code I'm using is actually the exact code like yours: a class library
have a base class, a control application has an inherited class. So It's
strange that your code doesn't work.

Is it possible that you forgot to assign value to the "name" field? If not
assigned (has null value), it will not be serialized in the resulting xml
file.

By the way, I just checked using Outlook Express that the attachment is ok
to download.

I've confirmed by evaluating the object (in debug mode) and the base class
has all of the properties assigned...

I'm only using Outlook, not outlook express, so I guess I can't seem to get
that attachment, but I don't think it will show my problem... can you email
me and I'll provide my code.

Thanks,
Mike
