Hi,

I am using IXmlSerializable interface for conversion of Dataset table objects in to XML format.
Please find the class example below.

public class SecondaryRNCTable: IXmlSerializable
{
   public void ReadXml(System.Xml.XmlReader reader)
   {
      IP = reader.GetAttribute("IP");
      int count = int.Parse(reader.GetAttribute("count"));
      reader.ReadStartElement();
      for (int i = 0; i < count; ++i)
      {
         reader.ReadStartElement();
         SecondaryRNC rnc = new SecondaryRNC();
         rnc.ReadXml(reader);
         Add(rnc);
      }
   }

   public void WriteXml(System.Xml.XmlWriter writer)
   {
      writer.WriteAttributeString("IP", parentDOMIP);
      writer.WriteAttributeString("count", Count.ToString());
      writer.WriteStartElement("SecondaryRNCs");
      foreach (SecondaryRNC rnc in this)
      {
         writer.WriteStartElement("SecondaryRNC");
         rnc.WriteXml(writer);
         writer.WriteEndElement();
      }
      writer.WriteEndElement();
   }
}

We add multiple datatables in a dataset say ds and
ds.writeXML(GZipOutputStream, XmlWriteMode.WriteSchema) is invoked to write in outputstream.
So for some tables, it also write assembly information shown below.
msdata:InstanceType="NeighborList.SecondaryRNCTable, projectName, Version=14.0.0.12, Culture=neutral, publicKeyToken=c2e771ef06d8dbb7"

How can I stop this insertion of string while writing in to outputstream?

Please provide input ASAP.

Thanks,
