    <p>...new to LINQ and could do with some help.</p> <p>I'm querying some remote xml and using LINQ to put the results into a List. When the xml query only returns 1 record all is fine and i get a fully populated 'GetMPResult' object by accessing [0] item in the list.</p> <p>...but, if there is more than 1 record returned in the xml, i get 'Use the new keyword to create an object instance' </p> <p>any ideas?</p> <pre><code>XDocument myData = XDocument.Parse(e.Result); List&lt;GetMPResult&gt; mp = (from mpItem in myData.Descendants("twfy") select new GetMPResult { Member_id = mpItem.Element("member_id").Value, House = mpItem.Element("house").Value, First_name = mpItem.Element("first_name").Value, Last_name = mpItem.Element("last_name").Value, Constituency = mpItem.Element("constituency").Value, Party = mpItem.Element("party").Value, Entered_house = mpItem.Element("entered_house").Value, Entered_reason = mpItem.Element("entered_reason").Value, Left_house = mpItem.Element("left_house").Value, Left_reason = mpItem.Element("left_reason").Value, Person_id = mpItem.Element("person_id").Value, Title = mpItem.Element("title").Value, Lastupdate = mpItem.Element("lastupdate").Value, Full_name = mpItem.Element("full_name").Value, Url = mpItem.Element("url").Value, Image = mpItem.Element("image").Value, Image_height = mpItem.Element("image_height").Value, Image_width = mpItem.Element("image_width").Value, }).ToList&lt;GetMPResult&gt;(); GetMPCompleteEvent(mp[0]); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
