title: How to use NPOI to read Excel spreadsheet that contains empty cells?
body: <p>When I read Excel worksheet using NPOI, empty cells are skipped. For example, it the row contains <code>A, B, , C</code> and I read it using </p>
  
  <pre><code>IRow row = sheet.GetRow(rowNb)
  </code></pre>
  
  <p>then <code>row.Cells[1].ToString()</code> will output <code>B</code> (as expected) but <code>row.Cells[2].ToString()</code> will output <code>C</code> instead of an empty string. Is there a way to keep empty cells? Thanks.</p>
