    <p>Expanding upon my <a href="https://stackoverflow.com/questions/489173/writing-xml-with-c">earlier problem</a>, I've decided to (de)serialize my config file class which worked great. </p> <p>I now want to store an associative array of drive letters to map (key is the drive letter, value is the network path) and have tried using <code>Dictionary</code>, <code>HybridDictionary</code>, and <code>Hashtable</code> for this but I always get the following error when calling <code>ConfigFile.Load()</code> or <code>ConfigFile.Save()</code>:</p> <blockquote> <p>There was an error reflecting type 'App.ConfigFile'. [snip] System.NotSupportedException: Cannot serialize member App.Configfile.mappedDrives [snip]</p> </blockquote> <p>From what I've read Dictionaries and HashTables can be serialized, so what am I doing wrong?</p> <pre><code>[XmlRoot(ElementName="Config")] public class ConfigFile { public String guiPath { get; set; } public string configPath { get; set; } public Dictionary&lt;string, string&gt; mappedDrives = new Dictionary&lt;string, string&gt;(); public Boolean Save(String filename) { using(var filestream = File.Open(filename, FileMode.OpenOrCreate,FileAccess.ReadWrite)) { try { var serializer = new XmlSerializer(typeof(ConfigFile)); serializer.Serialize(filestream, this); return true; } catch(Exception e) { MessageBox.Show(e.Message); return false; } } } public void addDrive(string drvLetter, string path) { this.mappedDrives.Add(drvLetter, path); } public static ConfigFile Load(string filename) { using (var filestream = File.Open(filename, FileMode.Open, FileAccess.Read)) { try { var serializer = new XmlSerializer(typeof(ConfigFile)); return (ConfigFile)serializer.Deserialize(filestream); } catch (Exception ex) { MessageBox.Show(ex.Message + ex.ToString()); return new ConfigFile(); } } } } </code></pre>

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.
