Serializer problem?

[Albert Jan]

Hi,

I use the XmlSerializer in C# to serialize an object containing an email
message to xml. This works often fine, but for some mailmessages the
serialization fails with the message 'There was an error generating the XML
document'

Can the serialization process be dependent on the data in the object
members? If so, what kind of data can cause this problem?

Any help is appreciated.

ps. the code used:

XmlSerializer serializer = new XmlSerializer(typeof(Pop3Message));
MemoryStream x=new MemoryStream() ;
TextWriter writer = new StreamWriter(x);
try
{
serializer.Serialize(writer, mess);
}
catch(Exception ex)
{
