    <p>I have the following XML</p> <pre><code>&lt;AllVendors xmlns="http://important/data"&gt; &lt;Vendor&gt; &lt;VendorId&gt;1&lt;/VendorId&gt; &lt;VendorName&gt;Vendor A&lt;/VendorName&gt; &lt;/Vendor&gt; &lt;Vendor&gt; &lt;VendorId&gt;2&lt;/VendorId&gt; &lt;VendorName&gt;Vendor B&lt;/VendorName&gt; &lt;/Vendor&gt; &lt;Vendor&gt; &lt;VendorId&gt;3&lt;/VendorId&gt; &lt;VendorName&gt;Vendor C&lt;/VendorName&gt; &lt;/Vendor&gt; &lt;/AllVendors&gt; </code></pre> <p>and the following CLR type</p> <pre><code>class Vendor { public Vendor(string vendorId, string vendorName) { VendorId = vendorId; VendorName = vendorName; } public string VendorId { get; set; } public string VendorName { get; set; } } </code></pre> <p>and the following basic interaction</p> <pre><code>class VendorInteraction { private List&lt;Vendor&gt; Vendors { get; set; } private void GetVendors(string xml) { var rawData = XElement.Parse(xml); XNamespace ns = Constants.TheNamespace; **var vendors = rawData.Descendants(ns + "AllVendors").Elements().Elements().Select(vendor =&gt; new Vendor(vendor.Value, vendor.Value)).ToList();** if (Vendors == null) Vendors = new List&lt;Vendor&gt;(); else Vendors.Clear(); Vendors.AddRange(vendors); } } </code></pre> <p>My goal is to return a List that would be projected based on a LINQ to XML query. The query that I have so far produces output like this:</p> <pre><code>1 1 Vendor A Vendor A 2 2 Vendor B Vendor B 3 3 Vendor C Vendor C </code></pre> <p>I would like each Vendor instance in the List to look like this:</p> <pre><code>1 Vendor A 2 Vendor B 3 Vendor C </code></pre> <p>I am not very good with LINQ and your help is tremendously appreciated!</p> <p><strong>Update: Actual solution</strong></p> <pre><code>var vendors = rawData.Descendants(ns + "AllVendors").Elements() .Select(x =&gt; new Vendor(x.Element(ns + "VendorId").Value, x.Element(ns + "VendorName").Value)) .ToList(); </code></pre> <p>@AVD and @BrokenGlass got me very close but it seems that I needed to get the Elements collection.</p>

    1. COWhy don't you consider deserializing to your `List<Vendor>`?

    2. CO@Munim Would you consider the XmlSerializer to be more efficient than LINQ to XML? What are the pros and cons of one approach over another?

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.
