compare dictionaries
<p>i have 3 generic dictionaries</p>

<pre><code>static void Main(string[] args)
{
    Dictionary&lt;string, string&gt; input = new Dictionary&lt;string, string&gt;();
    input.Add("KEY1", "Key1");

    Dictionary&lt;string, string&gt; compare = new Dictionary&lt;string, string&gt;();
    compare.Add("KEY1", "Key1");
    compare.Add("KEY2", "Key2");
    compare.Add("KEY3", "Key3");

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

<p>i'd like to take the list of input and compare each value to the compareTo list and if it doesn't exist add it to the results list?</p>
