title: cannot implicitly convert type int to system collections generic list
body: <p>I've been knocking my head on the wall with this for too long. 
  I'm making a blackjack game for school and I'm currently trying to get the card values and add them to their own list. </p>
  
  <p>When I have it set as a var as you see commented out on top it works fine, but when I try to switch it to a list I get the aformentioned error. I'm sure it is something easy I am missing. </p>
  
  <p>The error pops up at the end when I am trying to call the GetCardValue method. </p>
  
  <p>Thanks for any insight. </p>
  
  <pre><code>        /*var cardValue = 0;
          foreach (Card card in userHand)
          {
              card.GetCardValue();
              cardValue = card.GetCardValue();
          }*/
  
          List&lt;int&gt; cardValue = new List&lt;int&gt;();
          foreach (Card card in userHand)
          {
              card.GetCardValue();
              cardValue = card.GetCardValue();
          } 
  </code></pre>
