Serialize to XML using XSD

[Lars_V_J]

I'm making XML files from Entity Framework objects using this code:

           XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;
            settings.Encoding = utf8noBOM; 
            try
            {
                var rows = ef.message.Where(r => r.Rec_Status == 0); 
                foreach (var row in rows)
                {
                    filename = System.IO.Path.Combine(ConfigurationManager.AppSettings["XMLLogDirIncoming"].ToString(), row.REC_ID.ToString() + ".xml");
                    using (XmlWriter writer = XmlWriter.Create(filename, settings))
                    {
                        DataContractSerializer serializer = new DataContractSerializer(row.GetType());
                        serializer.WriteObject(writer, row);
                    }
                    files.Add(filename);
                }
            }
            catch (Exception ex)

But doing this, I get a lot of "crap" from EF which I don't need. Rather, I'd like the XML to conform to an XSD to reach a certain format. How do I do that? Can I specify an XSD for the serializer, or am I forced to transform my data afterwards?

Thanks in advance :-)

Select a new anonymous object with the fields you need.

The problem is, that my request comes from a gazillion tables (and there might be more in the future. But all have an EntityKey field which I don't need etc.
The things i _need_ are always different from table to table, while the things I _don't_ need are always the same.
I tried to experiment a bit with XML transformation, but with little luck.
I fear, that the only solution is something like the one you describe, but that will require code if or when a new table is added to the "collection".
