title: C# Dictionary of arrays
body: <p>Can I use C# Dictionary on classes like arrays??</p>
  
  <pre><code>Dictionary&lt;double[],double[]&gt;
  </code></pre>
  
  <p>I am afraid that it will not be able to tell when arrays are equal... </p>
  
  <p><strong>EDIT:<br></strong>
  Will the hashing method in the dictionary take well care of arrays? or just hashing their references?</p>
