Question

I presume this is possible? Basically i am receiving using LINQ (LINQ2Entities Entity Framework) data and return it to an IQUERYABLE once i this data i need to transform it to XML in a Memory Stream and a physical file on the hard disk – streamwriter??

Does anyone know if this is possible?

Any help really appreciated

Do i need to use LINQtoXML to accomplish this?

Any examples or tutorials anybody knows of would be great.

Thanks again

EDIT

After a little bit of investigation i think i require a XML Serializer for LINQ2Entities / IQueryable??

LINQ to XML is probably the best choice. You can use functional construction to create an XML tree in a single statement, like:

using (ContactEntities context = new ContactEntities()) {
    XDocument xml = new XDocument(
        new XElement("contacts",
            from contact in context.Contacts
            orderby contact.ContactId
            select new XElement("contact",
                new XAttribute("contactId", contact.ContactId),
                new XElement("firstName", contact.FirstName),
                new XElement("lastName", contact.LastName))));
    xml.Save(yourStream);
}
