title: List all Files and Folders from Google Drive V2 using .Net
body: <p>I am creating an application using Google Drive API in .Net using the Google API .Net client library. </p>
  
  <p>In that list request get all files from root folder as well as from child folders and shared files. I don't want to list them all. I want list of files which are available in root folders only, not from sub folders. Hows that possible?</p>
  
  <p>My code is below : </p>
  
  <pre><code> FilesResource.ListRequest listRequest = service.Files.List();
   var files = listRequest.Execute();
  </code></pre>
  
  <p>for that I have define scope as  </p>
  
  <pre><code>var Scopes = { DriveService.Scope.Drive };
  </code></pre>
