    <p>I have a List of a type named 'Complex':</p> <pre><code>List&lt;Complex&gt; list = new List&lt;Complex&gt;(); ... class Complex { public string Header { get; set; } ... ... ... } </code></pre> <p>There are some repeated headers in list, and these indicate the start of new sections. Each section may be of a different length, as shown below:</p> <pre><code>start 1 2 3 4 5 6 7 start 1 2 3 start 1 2 3 4 5 6 start 1 start 1 2 </code></pre> <p>I would like to get all possible sublists of type Complex using LINQ; that is, all objects with headers, as follows:</p> <ul> <li>1 2 3 4 5 6 7</li> <li>1 2 3</li> <li>1 2 3 4 5 6</li> <li>1</li> <li>1 2</li> </ul> <p>How can I accomplish this using LINQ only?</p> <p>edit: List is created during html page parsing</p> <pre><code>&lt;tr&gt; &lt;td&gt;00:00&lt;!--//-00:00--&gt;&lt;/td&gt; &lt;td&gt;15:00&lt;!--//-00:00--&gt;&lt;/td&gt; &lt;td class="txt_left"&gt;&lt;a href=""&gt;News&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="/TsV2/TV_Video_On.asp?PROG_CODE=TVCR0114"&gt; &lt;img src="/images/new/sub_new/icon_play01_off.gif" alt="play" class="rollover"/&gt;&lt;/a&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;00:15&lt;!--//-00:00--&gt;&lt;/td&gt; &lt;td&gt;15:15&lt;!--//-00:00--&gt;&lt;/td&gt; &lt;td class="txt_left"&gt; &lt;a href="Tv_Pagego.asp?PROG_CODE=TVCR0556"&gt;Nice one&lt;/a&gt;&lt;/td&gt; &lt;td&gt;&lt;a href="/TV2w/TV_2Video_On.asp?PROG_CODE=TVCR0556"&gt;&lt;img src="/images/new/sub_new/icon_play01_off.gif" alt="play" class="rollover"/&gt;&lt;/a&gt;&lt;/td&gt; &lt;/tr&gt; </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
