    <p>I have a list of key/value pairs I'd like to store in and retrieve from a XML file. So this task is similar as described <a href="https://stackoverflow.com/questions/284858/simplest-possible-key-value-pair-file-parsing-in-net">here</a>. I am trying to follow the advice in the marked answer (using a <strong>KeyValuePair</strong> and a <strong>XmlSerializer</strong>) but I don't get it working.</p> <p>What I have so far is a "Settings" class ...</p> <pre><code>public class Settings { public int simpleValue; public List&lt;KeyValuePair&lt;string, int&gt;&gt; list; } </code></pre> <p>... an instance of this class ...</p> <pre><code>Settings aSettings = new Settings(); aSettings.simpleValue = 2; aSettings.list = new List&lt;KeyValuePair&lt;string, int&gt;&gt;(); aSettings.list.Add(new KeyValuePair&lt;string, int&gt;("m1", 1)); aSettings.list.Add(new KeyValuePair&lt;string, int&gt;("m2", 2)); </code></pre> <p>... and the following code to write that instance to a XML file:</p> <pre><code>XmlSerializer serializer = new XmlSerializer(typeof(Settings)); TextWriter writer = new StreamWriter("c:\\testfile.xml"); serializer.Serialize(writer, aSettings); writer.Close(); </code></pre> <p>The resulting file is:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;Settings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt; &lt;simpleValue&gt;2&lt;/simpleValue&gt; &lt;list&gt; &lt;KeyValuePairOfStringInt32 /&gt; &lt;KeyValuePairOfStringInt32 /&gt; &lt;/list&gt; &lt;/Settings&gt; </code></pre> <p>So neither key nor value of the pairs in my list are stored though the number of elements is correct. Obviously I am doing something basically wrong. My questions are:</p> <ul> <li>How can I store the key/value pairs of the list in the file?</li> <li>How can I change the default generated name "KeyValuePairOfStringInt32" of the elements in the list to some other name like "listElement" I'd like to have?</li> </ul>

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.
