    <p>I have an Object with (de-)serializes its configuration via system.xml.serializer</p> <p>The config is in a class looking like this:</p> <pre><code> public struct Phase { public Int16 Trafo; public KorrekturWerte Spannung; public KorrekturWerte Strom; [XmlArray("Min")] public double[] Min; [XmlArray("Max")] public double[] Max; public bool CheckThis; } public class ParameterHardware { public string WAGOId = "00:30:DE:05:33:CB"; public Byte Phasen = 0x07; public Phase L1; public Phase L2; public Phase L3; } </code></pre> <p>(De-)Serializing this on a WindowsXP-System works just fine, but on Windows CE, the Min/Max-Array is just mussing after de- and then reserializing ("CheckThis" was put there as a test and follows after serializing the "Strom" values). As KorrekturWerte is again a struct, depth can't be the problem. The [XmlArray ...] wasn't there in my first version, it's just from another test.</p> <p>Edit:</p> <ul> <li><p>The Problem is not (only) in serialization. Trying to access Min[...] I get a null reference error.</p></li> <li><p>Maybe it's not clear: I have a serialization of the class, which contains <em>all</em> values. Deserialize it to initialize the class and then reserialize it as a debug-check. Now the fields are missing. (The original file was serialized in XP, where it works all right)</p></li> <li><p>Changeing the double[] to List does not help. (Same result) </p></li> <li><p>The xml-files: Original:</p> <p> 00:30:DE:05:53:65 1 50 -0.2 1 0.004 0.994 0 0 0 0 0 500 32 15000 15000 1 true 50 0 1 0 1 0 0 0 0 0 500 32 15000 15000 1 50 0 1 0 1 0 0 0 0 0 500 32 15000 15000 1 </p></li> </ul> <p>Reserialization (sorry, CE serializes in one single line):</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;&lt;ClassTest_FCT_Extern xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;&lt;Hardware&gt;&lt;WAGOId&gt;00:30:DE:05:53:65&lt;/WAGOId&gt;&lt;Phasen&gt;1&lt;/Phasen&gt;&lt;L1&gt;&lt;Trafo&gt;50&lt;/Trafo&gt;&lt;Spannung&gt;&lt;Offset&gt;-0.2&lt;/Offset&gt;&lt;Steigung&gt;1&lt;/Steigung&gt;&lt;/Spannung&gt;&lt;Strom&gt;&lt;Offset&gt;0.004&lt;/Offset&gt;&lt;Steigung&gt;0.994&lt;/Steigung&gt;&lt;/Strom&gt;&lt;CheckThis&gt;true&lt;/CheckThis&gt;&lt;/L1&gt;&lt;L2&gt;&lt;Trafo&gt;50&lt;/Trafo&gt;&lt;Spannung&gt;&lt;Offset&gt;0&lt;/Offset&gt;&lt;Steigung&gt;1&lt;/Steigung&gt;&lt;/Spannung&gt;&lt;Strom&gt;&lt;Offset&gt;0&lt;/Offset&gt;&lt;Steigung&gt;1&lt;/Steigung&gt;&lt;/Strom&gt;&lt;CheckThis&gt;false&lt;/CheckThis&gt;&lt;/L2&gt;&lt;L3&gt;&lt;Trafo&gt;50&lt;/Trafo&gt;&lt;Spannung&gt;&lt;Offset&gt;0&lt;/Offset&gt;&lt;Steigung&gt;1&lt;/Steigung&gt;&lt;/Spannung&gt;&lt;Strom&gt;&lt;Offset&gt;0&lt;/Offset&gt;&lt;Steigung&gt;1&lt;/Steigung&gt;&lt;/Strom&gt;&lt;CheckThis&gt;false&lt;/CheckThis&gt;&lt;/L3&gt;&lt;/ClassTest_FCT_Extern&gt; </code></pre> <ul> <li><p>Sorry for bringing everything slice by slice. Here is the serialization code (using System.Xml.Serialization;)</p> <pre><code>try { fstream = new FileStream(filepath, FileMode.Open, FileAccess.Read); reader = new XmlTextReader(fstream); serializer = new XmlSerializer(typeof(T)); retobj = (T)serializer.Deserialize(reader); } catch (Exception e) { Debug("Serialization: "+e.ToString()); retobj = Activator.CreateInstance&lt;T&gt;(); } </code></pre></li> </ul> <p>Debug is not called, so there don't seem to be any errors.</p> <ul> <li>The .net Version is 2.0</li> </ul>

    3. COIn your question you write the Min/Max-Array is missing, so you have to use a different datatype of write your own implementation on Windows CE.

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.
