How to find minimum key in dictionary
<p>I declare dictionary as following:</p>

<pre><code>private Dictionary&lt;int, touchInformation&gt; touchDictionary = new Dictionary&lt;int, touchInformation&gt;();
</code></pre>

<p>And I used as following:</p>

<p><code>touchDictionary[touchID]</code> = touchObject;</p>

<p>So, the touchDictionary will keep the key from touchID. Now, I try to find the minimum key using dictionary but I don't know how to do. Have any suggestion?</p>

<p>Regard,
