    <p>I'm having a problem when serializing a Dictionary containing a list of derived objects. The serialized output contains</p> <pre><code>&lt;BaseAttributes xsi:type="Turbine" Id="1975fe1f-7aa8-4f1d-b768-93ad262800cd"&gt; </code></pre> <p>where I would like the BaseAttributes to be substituted with Turbine and the xsi:type to be non-existing.</p> <pre><code>&lt;Turbine Id="1975fe1f-7aa8-4f1d-b768-93ad262800cd"&gt; </code></pre> <p>My code in overall looks like the following. I have a class BaseAttributes from which I derive some classes for example the Turbine class. These classes are stored in a dictionary with a List of BaseAttributes. The dictionary is an implemented serializable dictionary. Below is the code in general.</p> <pre><code>[XmlInclude(typeof(Turbine)), XmlInclude(typeof(Station)), XmlInclude(typeof(Substation))] public class BaseAttributes { [XmlAttribute("Id")] public Guid Id; } public class Turbine : BaseAttributes { private Element windSpeed; public Element WindSpeed { get { return windSpeed; } set { windSpeed = value; } } public Turbine(float windSpeed){ this.windSpeed= new Element(windSpeed.ToString(),"ms"); } //used for xmlserilization private Turbine(){} } public class CollectionOfBaseAttributes { public SerilizableUnitsDictionary&lt;DateTime, List&lt;BaseAttributes&gt;&gt; units; } [XmlRoot("dictionary")] public class SerilizableUnitsDictionary&lt;TKey, TValue&gt; : Dictionary&lt;TKey, TValue&gt;, IXmlSerializable { public System.Xml.Schema.XmlSchema GetSchema() { return null; } public void WriteXml(System.Xml.XmlWriter writer) { XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue), new XmlRootAttribute("Units")); foreach (TKey key in this.Keys) { writer.WriteStartElement("TimeStamp"); writer.WriteAttributeString("Value", key.ToString()); TValue value = this[key]; foreach (TValue value1 in Values) { valueSerializer.Serialize(writer, value1); } writer.WriteEndElement(); } } </code></pre> <p>I don't use a DataContractor for the serialization, as I will not be deserializing the XML. I "just" want to create the XML file with attributes.</p> <p>I have tried to use the XmlElementOverrides, but there is probably something that I just don' understand in the using. Currently I have tried to use it like this:</p> <pre><code>XmlAttributes attrs = new XmlAttributes(); XmlElementAttribute attr = new XmlElementAttribute(); attr.ElementName = "Turbine"; attr.Type = typeof(Turbine); attrs.XmlElements.Add(attr); XmlAttributeOverrides attrOverrides = new XmlAttributeOverrides(); attrOverrides.Add(typeof(CollectionOfBaseAttributes ), "BaseAttributes", attrs); XmlSerializer xmlSerializer = new XmlSerializer(typeof(CollectionOfBaseAttributes ),attrOverrides); </code></pre> <p>But no result from that.</p>

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.
