Compare two hashsets?
<p>I have two hashsets like this:</p>

<pre><code>HashSet&lt;string&gt; log1 = new HashSet&lt;string&gt;(File.ReadLines("log1.txt"));
HashSet&lt;string&gt; log2 = searcher(term);
</code></pre>

<p>How would I compare the two?</p>

<p>I want to make sure that <code>log2</code> does not contain any entries from <code>log1</code>. In other words, I want to remove all(if any), items that <code>log1</code> has inside <code>log2</code>.</p>
