How can I convert the integer output of an enum to a two character string?
<p>For the following Enum:</p>

<pre><code>public enum ContentKey {
    Menu = 0,
    Article = 1,
    FavoritesList = 2
};
</code></pre>

<p>The enum ContentKey returns an integer 0,1,2.  How can I convert or cast this so that it returns a two digit zero padded string "00", "01" .. "99" etc</p>
