title: Eliminating use of '2 dots' when using Excel Interop Com Objects - C#
body: <p>I am having trouble releasing Excel Interop Com Objects which is causing my c# application to crash when I attempt to save and then close an Excel workbook created via Excel Interop.  I feel the issue is that in some cases I am using '2 dots' with excel interop COM objects which from what I've read is not allowed.  I have eliminated 2 dots from most lines of code, but I am having troulbe figuring out a way to recreate the following lines of code so that they only use one dot.  If anyone has any suggestions I would greatly appreciate it.</p>
  
  <pre><code>workbook = (Excel.Workbook)app.Workbooks.Open(startForm.excelFileLocation,);
  
  workbook = (Excel.Workbook)app.Workbooks.Add(1);
  
  workSheet_range.Font.Color = System.Drawing.Color.FloralWhite.ToArgb();
  
  workSheet_range.Font.Bold = font;
  
  workSheet_range.Interior.Color = System.Drawing.Color.Red.ToArgb();
  </code></pre>
