title: c# - How to create 2D array with unknown number of rows, but known number of columns?
body: <p>I am trying to create 2-dimensional array of ints with two columns, but an unknown amount of rows. I know that in order to create the 2D array itself I do the following:</p>
  
  <pre><code>List&lt;List&lt;int&gt;&gt; myList = new List&lt;List&lt;int&gt;&gt;();
  </code></pre>
  
  <p>But how do I modify this to specify the number of columns? And how would I add a row to this array?</p>
