title: Access to the path 'C:\\Program Files (x86)\\IIS Express\\Excel.xlsx' is denied
body: <p>I'm working on a ASP.NET MVC 5 project. In this project I want user to download an Excel file using this code : </p>
  
  <pre><code>var workbook = new ExcelFile();
      workbook.Save("Excel.xlsx");
  </code></pre>
  
  <p>But when I enter the URL to download the Excel file. I get the exception : </p>
  
  <blockquote>
    <p>Access to the path 'C:\Program Files (x86)\IIS Express\Excel.xlsx'
    is denied.</p>
  </blockquote>
  
  <p>How can I modify my code so that user can download the Excel file wherever he wants? Instead of IIS Express folder. Thanks.</p>
