title: How to use no fill for background color of a excel cell using c#?
body: <p>With this:</p>
  
  <pre><code>using Excel = Microsoft.Office.Interop.Excel; 
  </code></pre>
  
  <p>I'm opening the excel and after I'm setting the color of the first cell to transparent like this:</p>
  
  <pre><code>xlRange = xlWorkSheet.get_Range("A1");
  xlRange.Interior.Color = System.Drawing.Color.Transparent;
  </code></pre>
  
  <p>The problem is that it puts white and the "borders" disappear. I want to put the "No Fill" option and it's not working.</p>
  
  <p>I've also tried this:</p>
  
  <pre><code>xlRange.Interior.Color = System.Drawing.Color.Empty;
  </code></pre>
  
  <p>but then it changed the cell color to black.</p>
  
  <hr>
  
  <p>How can I solve this?</p>
