title: Get all the cell values from excel using EPPlus
body: <p>I want to use the ExcelWorksheet object from the EPPlus library and retrieve all the cells with values as well as their positions.</p>
  
  <p>At the end of the day, I want a dictionary similar to this.</p>
  
  <pre><code>Dictionary&lt;KeyValuePair&lt;int, int&gt;, object&gt; values.
  </code></pre>
  
  <p>I am looking for a nice and clean way to extract the cell values into this dictionary for use. </p>
  
  <p>I am quite aware that you can reference the cell values directly as below, but is there a nice clean way of extracting all the data ?</p>
  
  <pre><code>worksheet.Cells[row, column];
  </code></pre>
