title: Get first key from Dictionary<string, string>
body: <p>I'm using a <code>System.Collections.Generic.Dictionary&lt;string, string&gt;</code>.</p>
  
  <p>I want to return the first key from this dictionary. I tried <code>dic.Keys[0]</code> but the only thing I have on the <code>Keys</code> property (which is a <code>KeyCollection</code> object) is an enumerator.</p>
  
  <p>Do I have to enumerate through all the keys to get the first one?</p>
