Exception while creating XmlSerializer with XmlAttributeOve rrides.

I am using XmlSerializer with XmlAttributeOve rrides. The
XmlAttributeOve rrides are used for properties which hold element/s
derived from "AbstractMessag e" type.

System.Xml.Seri alization.XmlRo otAttribute(Nam espace = "http://
www.TestNameSpa ce.org/Test-4-4", IsNullable = false)]
class Root
[System.Xml.Seri alization.XmlEl ementAttribute( Type =
typeof(Abstract _message), ElementName = "Message", IsNullable =
public virtual Abstract_messag e Message
get { return this._messageFi eld; }
set{ this._messageFi eld = value; }

[System.Xml.Seri alization.XmlEl ementAttribute( Type =
typeof(BatchMes ssage), ElementName = "Batch", IsNullable = false)]
public virtual Batch_tCollecti on Batch
get { return this._batchFiel d; }
set{ this._batchFiel d = value; }

[System.Xml.Seri alization.XmlTy peAttribute(Nam espace = "http://
www.TestNameSpa ce.org/Test-4-4")]
public class BatchMesssage
[System.Xml.Seri alization.XmlEl ementAttribute( "Hdr", Order =
0, IsNullable = false)]
public BatchHeader_t Hdr
get{ return this._hdrField; }
set { this._hdrField = value; }
[System.Xml.Seri alization.XmlEl ementAttribute( "Message", Order
= 1, IsNullable = false, Type = typeof(Abstract _message_t))]
public Abstract_messag e_tCollection Messages
get { return this._messageFi eld; }
set { this._messageFi eld = value; }

where type "Batch_tCollect ion" is a collection of "BatchMessa ge" type
For type "Root" "BatchMessa ge" I provide XmlAttributeOve rrides for
property "Message" & "Messages" respt. :

System.Xml.Seri alization.XmlAt tributeOverride s attribOverrides = new
System.Xml.Seri alization.XmlAt tributeOverride s();
System.Xml.Seri alization.XmlAt tributes msgAttribs = new
System.Xml.Seri alization.XmlAt tributes();
msgAttribs.XmlE lements.Add(new
System.Xml.Seri alization.XmlEl ementAttribute( "TestMessageRoo t",
typeof(TestMess age)));
attribOverrides .Add(typeof(Roo t), "Message", msgAttribs);
attribOverrides .Add(typeof(Bat chMesssage), "Message", msgAttribs);

where type "TestMessag e" is derived from "AbstractMessag e" type.
When I try to instantiate the XmlSerializer with the above
XmlAttributeOve rrides as parameter to the constructor it throws the
following exception:

System.InvalidO perationExcepti on was caught
Message="There was an error reflecting type 'Root'."
Source="System. Xml"
System.Xml.Seri alization.XmlRe flectionImporte r.ImportTypeMap ping(TypeModel
model, String ns, ImportContext context, String dataType,
XmlAttributes a, Boolean repeats, Boolean openModel)
System.Xml.Seri alization.XmlRe flectionImporte r.ImportElement (TypeModel
model, XmlRootAttribut e root, String defaultNamespac e)
System.Xml.Seri alization.XmlRe flectionImporte r.ImportTypeMap ping(Type
type, XmlRootAttribut e root, String defaultNamespac e)
at System.Xml.Seri alization.XmlSe rializer..ctor( Type type,
XmlAttributeOve rrides overrides, Type[] extraTypes, XmlRootAttribut e
root, String defaultNamespac e, String location, Evidence evidence)
at System.Xml.Seri alization.XmlSe rializer..ctor( Type type,
XmlAttributeOve rrides overrides, Type[] extraTypes, XmlRootAttribut e
root, String defaultNamespac e)

Inner Exception: There was an error reflecting property 'Batch'.
Inner Exception: There was an error reflecting type 'BatchMessage'.
Inner Exception: Inconsistent sequencing: if used on one of the
class's members, the 'Order' property is required on all particle-like
members, please explicitly set 'Order' using XmlElement, XmlAnyElement
or XmlArray custom attribute on class member 'Messages'.
In the above case if I remove the sequencing property ("Order") from
the XmlElementAttri bute applied on BatchMessage member properties, the
thing seems to work correctly.

Am I using the XmlAttributeOve rride in the right place? Any help on
the above will be appreciated.
Thanks in advance.

Dear all, I have a set of c# data classes which i need to fill their data from xml files. serialization looks to be the best way to accomplish this task. Since the data classes are compiled and i don't have control on the xml structure, I tried using the xmlAttributeOverrides class, to instruct the serializer. I was able to override the attributes for the root element, but I'm having problems understanding how to deserialize arrays.

Hello, Is there a way of telling the XmlSerializer to ignore all namespaces when deserializing. I'm using XmlAttributeOverrides, but I have to do it for every class the OutputObject usses. Is there an "ApplyToAll" kind of feature? I also tried the defaultNamespace, but it didn't work.

Hi, I've hit quite a strange problem with XmlSerializer on my W2K3 server. When I serialize/deserialize using an exe on my local computer (XP), everything works fine. When I put the code out on the server (W2K3) it throws an exception. It only seems to happen when serializing/deserializing _arrays_ of a type. If I just serialize/deserialize one instance, it works fine. The exception I get is: (sorry for the word wrapping.)...

Using the XmlSerializer to deserialize a double.NaN value generates an exception in the framework which the framework then catches.
