title: Modify elements in a list by index
body: <p>I need to modify a <code>List&lt;int&gt;</code>  by indexes. I have the indexes in another <code>List&lt;int&gt;</code></p>
  
  <pre><code>List&lt;int&gt; values;
  List&lt;int&gt; indexes;
  
  indexes.Select(i=&gt;values[i]).ForEach(val=&gt;val = 0);
  </code></pre>
  
  <p>Of course, I know the above syntax wont work. However, as I know the indexes of the items that I need to modify, I would like to to modify the list with the indexes with lambda. Is it possible to do that?</p>
