Serialization problem with late binding

[Sacha]

I'm having trouble serializing some of my classes when using late binding.
When I don't use late binding, it works fine. MyClass inherit from an
abstract class called
AbsMyClass.

If I do the following, it works fine:
#BEGIN
public static void Write( string fileName ){
MyClass myClass = null;
XmlSerializer xmlSerializer = null;
Stream stream = null;

myClass = new MyClass();

xmlSerializer = new XmlSerializer( myClass.GetType () );
stream = new FileStream(file Name, FileMode.Create ,
FileAccess.Writ e, FileShare.None) ;

xmlSerializer.S erialize(stream , gen);
stream.Close();
}
#END

If I do the following, I get a error msg

#BEGIN
public static void Write( string fileName ){
AbsMyClass myAbsClass = null;
XmlSerializer xmlSerializer = null;
Stream stream = null;

//This will get a pre-created myAbsClass using reflection
// The GetAbsClass is used in many other places in my code and it
// correctly return a pre-created class of the right type.
myAbsClass = GetAbsClass("My FullClassName") ;

xmlSerializer = new XmlSerializer(
myAbsClass.GetT ype() );
stream = new FileStream(file Name, FileMode.Create ,
FileAccess.Writ e, FileShare.None) ;

xmlSerializer.S erialize(stream , gen);
stream.Close();
}
#END

#ERROR

Sacha,

Can you give the message that comes with the Exception?
