    <p>Say you have a <em>Player</em> class that looks like:</p> <pre><code>[XmlRoot] public class Player { [XmlElement] public int Level { get; set; } [XmlElement] public int Health { get; set; } } </code></pre> <p>Here is a complete round-trip to get you started:</p> <pre><code>XmlSerializer xmls = new XmlSerializer(typeof(Player)); StringWriter sw = new StringWriter(); xmls.Serialize(sw, new Player { Level = 5, Health = 500 }); string xml = sw.ToString(); Player player = xmls.Deserialize(new StringReader(xml)) as Player; </code></pre> <p><em>xml</em> is:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-16"?&gt; &lt;Player xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt; &lt;Level&gt;5&lt;/Level&gt; &lt;Health&gt;500&lt;/Health&gt; &lt;/Player&gt; </code></pre> <p>And you guess <em>player</em> is exactly the same as the original object we serialized.</p> <p>If you want to serialize to/deserialize from files you can do something like:</p> <pre><code>using (var stream = File.OpenWrite("my_player.xml")) { xmls.Serialize(stream, new Player { Level = 5, Health = 500 }); } Player player = null; using (var stream = File.OpenRead("my_player.xml")) { player = xmls.Deserialize(stream) as Player; } </code></pre> <p><strong>EDIT:</strong></p> <p>IF you want exactly the XML you show:</p> <pre><code>XmlSerializer xmls = new XmlSerializer(typeof(Player)); XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); ns.Add("", ""); XmlWriterSettings settings = new XmlWriterSettings { OmitXmlDeclaration = true, Indent = true }; using (var stream = File.OpenWrite("my_player.xml")) { using (var xmlWriter = XmlWriter.Create(stream, settings)) { xmls.Serialize(xmlWriter, new Player { Level = 5, Health = 500 }, ns); } } Player player = null; using (var stream = File.OpenRead("my_player.xml")) { player = xmls.Deserialize(stream) as Player; } </code></pre>

    2. COAlso, can you please explain these parts: <Player xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> xmls.Serialize(sw, new Player { Level = 5, Health = 500 }); string xml = sw.ToString(); Player player = xmls.Deserialize(new StringReader(xml)) as Player;

    3. CO*Serialize* produces the XML representation of your objects. *Deserialize* does the opposite: produces objects from their XML representation.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
