 var result = (
                         from contact in db.Contacts                             
                         join user in db.Users on contact.CreatedByUserID equals user.UserID
                         orderby contact.ContactID descending
                         select new ContactListView
                         {
                             ContactID = contact.ContactID,
                             FirstName = contact.FirstName,
                             LastName = contact.LastName,
                             Company = (from field in contact.XmlFields.Descendants("Company")
                                           select field.Value).SingleOrDefault().ToString()
                         }).Take(10);

Here I described how my database tables look like. So, contacts table has one field that is xml type. In that field is stored Company filename and I need to read it. I tried it using this way:

Company = (from field in contact.XmlFields.Descendants("Company")
                                               select field.Value).SingleOrDefault().ToString()
                             }).Take(10);

but I get following error:

Member access 'System.String Value' of 'System.Xml.Linq.XElement' not legal on type 'System.Collections.Generic.IEnumerable`1[System.Xml.Linq.XElement].

Any solution for this?

Thanks in advance,
Ile
