    <p>I've made my own tree data structure via classes. Now I'm stuck with really basic stuffs. I need to make output tab delimited file from data in <em>my List <code>&lt;MainTreeNode&gt;</code></em>.<br> I think that recursion is only way?!</p> <p>Tree is N-tree, and output have first row as header and other rows are values.</p> <p><strong>Tree:</strong></p> <blockquote> <ol> <li>MSG (MainTreeNode) <ul> <li>MainParam (Must have prop NAME, doesn't have to have prop VALUE) <ul> <li>SubParam1 (Must have prop NAME, must have prop VALUE) </li> <li>SubParam2 (Must have prop NAME, doesn't have to have prop VALUE) <ul> <li>SubSubParam2.1 (Must have prop NAME, must have prop VALUE)<br> etc. </li> </ul></li> </ul></li> </ul></li> </ol> </blockquote> <p><strong>Or:</strong></p> <blockquote> <ol> <li>Message : Name <ul> <li>Param1 : ValueV1 (VALUE must, because it doesn't have children)</li> <li>Param2 <ul> <li>Param2.1 : ValueV2</li> <li>Param2.2 : Value <ul> <li>Param2.2.1 : ValueV3</li> <li>Param2.2.2 : ValueV4 ...etc.</li> </ul></li> </ul></li> </ul></li> </ol> </blockquote> <p>And output have to be like this (first line is header):</p> <pre><code>Param1|Param2/Param2.1|Param2/Param2.2/Param2.2.1|Param2/Param2.2/Param2.2.2 ValueV1|ValueV2|ValueV3|ValueV4 ... </code></pre> <p>So I need probably List for header and for values but I don't know how to implement that in recursion way (or any another).</p> <p>Some of unfinished code:</p> <pre><code>public void PrintToTabFile(List&lt;Message&gt; messages, List&lt;string&gt; parameters) { foreach (string s in parameters) { using (StreamWriter streamWriter = new StreamWriter(@"C:\temp\" + s + ".xls")) { streamWriter.Write("No.\tMsgName\tMsgData1\tMsgData2\tMsgData3"); var msg = messages.Where(x =&gt; x.Parameters.Where(p =&gt; p.ParameterName == s).Count() == 1); List&lt;string&gt; headers = new List&lt;string&gt;(); List&lt;string&gt; values= new List&lt;string&gt;(); //... Stuck!!! } } } private void Recursion(Parameter parameter, List&lt;string&gt; headers, List&lt;string&gt; values) { if (parameter.SubParameters.Count == 0) { int index = headers.IndexOf(parameter.ParameterName); values[index] = parameter.ParameterValue; } else { foreach (Parameter p in parameter.SubParameters) { Recursion(p, headers, values); //and Stuck Probably here or before recursion call } } } </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.
