How to loop through this dictionary
<p>I have declared a dictionary like this:</p>

<pre><code>Dictionary&lt;string, KeyValuePair&lt;string, string&gt;&gt; dc = new Dictionary&lt;string, KeyValuePair&lt;string, string&gt;&gt;();
</code></pre>

<p>now how can I loop through it? I wanted something like the following so I created that dictionary:</p>

<p>name1
oldValue1
newValue1</p>

<p>name2
oldValue2
newValue2</p>

<p>...</p>
