body: <p>I am using EPPlus to create excel sheet from existing template.</p>
  
  <p>My code uploaded on azure blob storage. which is used by Azure data factory custom activity.</p>
  
  <p>for This activity I need to use template excel file which is in azure blob.</p>
  
  <p>I want to give URL for template file.</p>
  
  <pre><code>var newFile = new FileInfo("Report_Template.xlsx");
  </code></pre>
  
  <p>Is there any solution or alternative?</p>
