title: ASP.NET MVC - How can I check if a file exists on an ftp server
body: <p>I'm working on an ASP.NET MVC 5.1 web site, and I need to show a picture if it exists in an ftp server (CDN). Foldername and filename are tied to rules so I know them beforehand. I need to display a message if this file does not exist.</p>
  
  <p>How can I check if this file exists?</p>
  
  <p><a href="https://stackoverflow.com/questions/415962/verify-if-file-exists-or-not-in-c-sharp">Suggested duplicate (Verify if file exists or not in C#)</a> does not help since I need to check if the file exists on a <em>remote</em> server and not a <em>local</em> folder.</p>
