title: How can a border be set around multiple cells in excel using C#
body: <p>I am working on a project that creates excel files.</p>
  
  <p>I am having trouble placing a border on multiple cells to organize the excel file. </p>
  
  <p>Let's say I want a border from cell B5 to B10. There shouldn't be borders between B5, B6, B7,...</p>
  
  <p>Currently, I have this code: </p>
  
  <pre><code>workSheet_range = worksheet.get_Range("B5", "B10");
  workSheet_range.Borders.Color = System.Drawing.Color.Black.ToArgb();
  </code></pre>
  
  <p>It makes the borders, however it places a border around every cell instead of one big border for all cells. </p>
  
  <p>How can I accomplish this? </p>
