Find a string in an ArrayList
<p>I want to find a string in <code>Arraylist</code>. For example;</p>

<pre><code>ArrayList al = new ArrayList { "aa", "bb", "cc", "dd" };
string test = "aa";
</code></pre>

<p>But the following doesn't compile:   </p>

<pre><code>if(ArrayList.Equals(test))
</code></pre>

<p><strong>Note</strong>: I would prefer to not write out my own loop to search for the String</p>
