    <p>I have an object <code>InputFile</code> that has arrays and objects to hold the contents of a file. I also have <code>ABCFile</code> and <code>XYZFile</code> that are both inherited from <code>InputFile</code> that will read different types of file and store them into the projected members of <code>InputFile</code>.</p> <p>Since the serialization and deserialization of both of these objects are identical to the parent object, I have implemented a standard XML serialization interface on the parent object. During deserialization a few paramters are read, a <code>Read</code> function is called (to load a file), then the deserialization finishes.</p> <p>The serialization works great, but the deserialization (of <code>List&lt;InputFile&gt;</code>) doesn't work because the deserializer calls the parents stub <code>Read</code> file function instead of <code>ABCFile</code> or <code>XYZFile</code>'s.</p> <p>How can I get the deserialization to recognize the correct type of object to use? It is possible that my <code>List&lt;InputFile&gt;</code> will have a mix of file types.</p> <p>Thanks</p> <p>The code I use to serialize the object:</p> <pre><code>public class InputFileHolder : IXmlSerializable { ... public void WriteXml(XmlWriter w) { XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); ns.Add("", ""); XmlSerializer ifXml = new XmlSerializer(typeof(List&lt;InputFile&gt;)); ifXml.Serialize(w, InputFiles, ns); //More serialization } </code></pre> <p>Any ideas how to maintain the object type when I custom serialize the List?</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.
