title: Convert a list of strings to a single string
body: <pre><code>List&lt;string&gt; MyList = (List&lt;string&gt;)Session["MyList"];
  </code></pre>
  
  <p><code>MyList</code> contains values like: <code>12</code> <code>34</code> <code>55</code> <code>23</code>.</p>
  
  <p>I tried using the code below, however the values disappear.</p>
  
  <pre><code>string Something = Convert.ToString(MyList);
  </code></pre>
  
  <p>I also need each value to be separated with a comma ("<code>,</code>").</p>
  
  <p>How can I convert <code>List&lt;string&gt; Mylist</code> to <code>string</code>?</p>
