title: linq query in list<list<T>>
body: <p>I want to extract only the elements of List corresponding to a specific index from List&lt;List&gt;.<br />
  Tried to do this using LINQ Query and not For or Foreach, but I wasn't lucky<br />
  I want the result like below</p>
  <pre><code>List&lt;List&lt;string&gt;&gt; list = new List&lt;List&lt;string&gt;&gt;();
  list.Add(new List&lt;string&gt; { &quot;1&quot;, &quot;2&quot;, &quot;3&quot; });
  list.Add(new List&lt;string&gt; { &quot;A&quot;, &quot;B&quot;, &quot;C&quot; });
  
  // expectation result List : index 1
  // { &quot;2&quot;, &quot;B&quot; }
  </code></pre>
