title: How to check if dictionary's enumerator is null?
body: <p>I am using c# code and curious about checking if Enumerator structure is empty or not.</p>
  
  <p>What I guess is like this.</p>
  
  <pre><code>Dictionary&lt;key, value&gt; dicItems = new Dictionary&lt;key, value&gt;();
  
  Dictionary&lt;key, value&gt;.Enumerator handyEnumerator = dicItems.GetEnumerator();
  
  void UpdateEveryFrame()
  {
      if(handyEnumerator == default(????))  // do something..
  }
  </code></pre>
  
  <p>In fact, I will do by counting dictionary's count. </p>
  
  <p>But I totally want to know how to set Enumerator of dictionary to default(type).</p>
  
  <p>Anyone?</p>
