    <p>I have a problem when attempting to serialize class on a server, send it to the client and deserialize is on the destination.</p> <p>On the server I have the following two classes:</p> <pre><code>[XmlRoot("StatusUpdate")] public class GameStatusUpdate { public GameStatusUpdate() {} public GameStatusUpdate(Player[] players, Command command) { this.Players = players; this.Update = command; } [XmlArray("Players")] public Player[] Players { get; set; } [XmlElement("Command")] public Command Update { get; set; } } </code></pre> <p>and</p> <pre><code>[XmlRoot("Player")] public class Player { public Player() {} public Player(PlayerColors color) { Color = color; ... } [XmlAttribute("Color")] public PlayerColors Color { get; set; } [XmlAttribute("X")] public int X { get; set; } [XmlAttribute("Y")] public int Y { get; set; } } </code></pre> <p>(The missing types are all enums).</p> <p>This generates the following XML on serialization:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-16"?&gt; &lt;StatusUpdate&gt; &lt;Players&gt; &lt;Player Color="Cyan" X="67" Y="32" /&gt; &lt;/Players&gt; &lt;Command&gt;StartGame&lt;/Command&gt; &lt;/StatusUpdate&gt; </code></pre> <p>On the client side, I'm attempting to deserialize that into following classes:</p> <pre><code>[XmlRoot("StatusUpdate")] public class StatusUpdate { public StatusUpdate() { } [XmlArray("Players")] [XmlArrayItem("Player")] public PlayerInfo[] Players { get; set; } [XmlElement("Command")] public Command Update { get; set; } } </code></pre> <p>and</p> <pre><code>[XmlRoot("Player")] public class PlayerInfo { public PlayerInfo() { } [XmlAttribute("X")] public int X { get; set; } [XmlAttribute("Y")] public int Y { get; set; } [XmlAttribute("Color")] public PlayerColor Color { get; set; } } </code></pre> <p>However, the deserializer throws an exception:</p> <pre><code>There is an error in XML document (2, 2). &lt;StatusUpdate xmlns=''&gt; was not expected. </code></pre> <p>What am I missing or doing wrong?</p> <p>EDIT:</p> <p>On request I'm also adding code used to serialize and deserialize:</p> <p>Server:</p> <pre><code> public static byte[] SerializeObject(Object obj) { XmlSerializer xmlSerializer = new XmlSerializer(obj.GetType()); StringWriter writer = new StringWriter(); // Clear pre-defined namespaces XmlSerializerNamespaces xsn = new XmlSerializerNamespaces(); xsn.Add("", ""); xmlSerializer.Serialize(writer, obj, xsn); writer.Flush(); // Send as little-endian UTF-16 string because the Serializer denotes XML as // utf-18 which cannot be easly changed UnicodeEncoding encoder = new UnicodeEncoding(false, false); return encoder.GetBytes(writer.ToString()); } </code></pre> <p>Client:</p> <pre><code> public static object DeserializeXml(string xmlData, Type type) { XmlSerializer xmlSerializer = new XmlSerializer(type); StringReader reader = new StringReader(xmlData); object obj = xmlSerializer.Deserialize(reader); return obj; } </code></pre> <p>Deserialization is invoked with</p> <pre><code>StatusUpdate update = (StatusUpdate) Util.DeserializeXml(xmlData, typeof (StatusUpdate)); </code></pre>

    1. COThe first thing you're missing is not showing us the code you're using to deserialize.

    2. COThis is still incomplete. Where does the string `xmlData` come from when it's serialized as bytes on the other end? I wouldn't be surprised if this is actually an encoding issue. And why does your comment mention "utf-18" when there's no such thing?

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.

SQuiL has stopped working due to an internal error.

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