    <p>My XML file looks something like this:</p> <pre><code>&lt;MyXml&gt; &lt;Version&gt; 9.3.2 &lt;/Version&gt; &lt;Resources&gt; &lt;Sets&gt; &lt;ItemCollection&gt; &lt;Item&gt; &lt;Name&gt; Name &lt;/Name&gt; &lt;Age&gt; 66 &lt;/Age&gt; &lt;/Item&gt; &lt;/ItemCollection&gt; &lt;/Sets&gt; &lt;/Resources&gt; </code></pre> <p>I'm trying to get to the items within the ItemCollection, but so far, not luck at all; this is what my code looks like:</p> <pre><code>Stream reader = new FileStream(fileLocation, FileMode.Open); XmlSerializer s = new XmlSerializer(typeof(MyClass)); var items = s.Deserialize(reader) as MyClass; </code></pre> <p>And my objects look like:</p> <pre><code>[Serializable] [XmlRoot("MyXml")] public class MyClass { [XmlElement("Version")] public string Version { get; set; } [XmlElement("Resources")] public List&lt;Resources&gt; Resources{ get; set; } } [Serializable] public class Resources { [XmlElement("Sets")] public List&lt;Sets&gt; Sets { get; set; } } [Serializable] public class Sets { [XmlArray(ElementName = "ItemCollection")] [XmlArrayItem("Item")] public List&lt;Item&gt; Items { get; set; } } [Serializable] public class Item { [XmlElement("Name")] public string Name{ get; set; } [XmlElement("Age")] public string Age { get; set; } } </code></pre> <p>I can get the version just fine, and the hierarchy looks fine, but Name and Age from the Item object are always null. I've tried XmlElement instead of the XmlArray, but that doesn't work either.</p> <p>Any help on how to achieve this will be much appreciated!!! </p> <p><strong>EDIT:</strong> The example I gave was a simplification of the XML that I receive: it is actually a call to the location REST service from the BING API; the XML I get looks like the one in this URL:</p> <p><a href="http://msdn.microsoft.com/en-us/library/ff701710.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/ff701710.aspx</a></p> <p>and what I'm trying to put in my structures are the information within the Location element. </p> <p>My real objects look like this:</p> <pre><code>[Serializable] [XmlRoot("Response")] public class LocationService { [XmlElement("StatusCode")] public string Code{ get; set; } [XmlElement("ResourceSets")] public List&lt;ResourceSets&gt; ResourceSets{ get; set; } } [Serializable] public class ResourceSets { [XmlElement("ResourceSet")] public List&lt;ResourceSet&gt; ResourceSet { get; set; } } [Serializable] public class ResourceSet { [XmlArray(ElementName = "Resources")] [XmlArrayItem("Location")] public List&lt;Location&gt; Locations { get; set; } } [Serializable] public class Location { [XmlElement("Latitude")] public string Latitude{ get; set; } [XmlElement("Longitude")] public string Longitude{ get; set; } } </code></pre> <p>Hopefully this will clarify even further what I'm trying to achieve here.</p> <p>Thanks!</p>

    1. COSo you can generate that structure but not read it back?

    2. COYou don't need the Serializable attribute, it's intended to use with Formatter's derived serializer (BinaryFormatter, SoapFormatter). XmlSerializer relays solely on public properties. I.e. class is serializable via XmlSerializer if and only if it is public and has accessible default constructor. And you also don't need XmlElement attributes where element name is the same as property name. Btw, did you forget the closing tag for MyXml? Because without it the XML structure is invalid.

    3. CO@Dmitry Lobanov Well, thanks for all that info. The best part of asking questions is all the stuff you get to learn. And the file is just an example I put together following the structure of the real XML file. @drachenstern: I get the XML file from a REST service call. I thought making it a simple one would help solving the problem, but I'm guessing I was way off. I'll edit the question.

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.
