    <p>In my application I have a <code>PacketList</code> class and <code>Packet</code> class. I'd like to be able to use the serialization helpers on <code>PacketList</code> to come up with something like the desired output, but have no idea what direction to go in.</p> <p>I am writing a program to imitate a server which has a peculiar protocol for sending data.</p> <p>Client sends data with format: <code>COMMAND|ARGUMENT_0|ARGUMENT_1|ARGUMENT_2|...|ARGUMENT_N\0</code>. Where <code>COMMAND</code> could be something like <code>MOVE</code> or <code>LOGIN</code>.</p> <p>The server would respond in the format:</p> <pre><code>&lt;p c='COUNT'&gt; &lt;m p='N' p0='COMMAND_0' p1='ARUGMENT_0' ... pN='ARGUMENT_N'/&gt; &lt;m p='N' p0='COMMAND_1' p1='ARUGMENT_0' ... pN='ARGUMENT_N'/&gt; &lt;m p='N' p0='COMMAND_2' p1='ARUGMENT_0' ... pN='ARGUMENT_N'/&gt; &lt;m p='N' p0='COMMAND_3' p1='ARUGMENT_0' ... pN='ARGUMENT_N'/&gt; ... &lt;m p='N' p0='COMMAND_COUNT' p1='ARUGMENT_0' ... pN='ARGUMENT_N'/&gt; &lt;/p&gt; </code></pre> <p>Where <code>COMMAND_0</code> could be something like <code>UPDATE_POSITION</code> or <code>AUTHENTICATED</code>.</p> <p>Yes, this is a silly way of doing things. No, I don't know why it's done this way. No, I can't change it.</p> <p>Anyways, I am looking to emulate the way that the server sends the packet back to the client. What I have gotten so far is:</p> <pre><code>XmlWriterSettings _Settings = new XmlWriterSettings { OmitXmlDeclaration = true, Indent = true }; StringBuilder _Xml = new StringBuilder(); XmlWriter _Writer = XmlWriter.Create(_Xml, _Settings); _Writer.WriteStartElement("p"); _Writer.WriteAttributeString("c", "1"); _Writer.WriteStartElement("m"); _Writer.WriteAttributeString("p", "2"); _Writer.WriteAttributeString("p0", "COMMAND"); _Writer.WriteAttributeString("p1", "ARGUMENT_0"); _Writer.WriteAttributeString("p2", "ARGUMENT_1"); _Writer.WriteEndElement(); // &lt;/m&gt; _Writer.WriteEndElement(); // &lt;/p&gt; _Writer.Flush(); Console.WriteLine(_Xml.ToString()); </code></pre> <p>This works properly and outputs:</p> <pre><code>&lt;p c="1"&gt; &lt;m p="2" p0="COMMAND" p1="ARGUMENT_0" p2="ARGUMENT_1" /&gt; &lt;/p&gt; </code></pre> <p>However, I'd like to implement this in a cleaner way.</p> <p>My <code>PacketList</code> basically contains a list of <code>Packet</code>s, and <code>Packet</code> contains a <code>String _Command</code> and <code>String[] _Arguments</code>.</p> <p>If anyone could guide me in the right direction it would be much appreciated.</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.
