Even if you are using file page type - behind the scene you are still working with attachments. You should look at <a href="https://docs.kentico.com/api9/content-management/attachments" rel="nofollow noreferrer">attachment api</a> and <a href="http://devnet.kentico.com/docs/10_0/api/html/Methods_T_CMS_DocumentEngine_AttachmentInfoProvider.htm" rel="nofollow noreferrer">AttachmentInfoProvider</a> class

so if you have page object you can do something like

<pre><code>DocumentAttachment da = page?.AllAttachments.FirstOrDefault();
</code></pre>

or

<pre><code> var attachment = AttachmentInfoProvider.GetAttachments()
 .WhereEquals("ColumnFromCMS_Attachment", "value")
 .FirstOrDefault();
</code></pre>

Not sure which one is more applicable, but it should give you the idea...

P.S. you may also take a look <a href="https://github.com/Kentico/Mvc/search?q=attachment&amp;unscoped_q=attachment" rel="nofollow noreferrer">kentico MVC project on github and search for attachment</a>

P.P.S. Check as well <a href="https://docs.kentico.com/k11/developing-websites/developing-sites-using-asp-net-mvc/developing-mvc-applications/retrieving-content-on-mvc-sites/working-with-page-attachments-in-mvc-applications" rel="nofollow noreferrer">Working with page attachments in MVC applications</a>

Thanks so much for the pointers. I was able to get the attachment and return to browser using following approach. The key was using GUID of attachment, but name of the document. 

Code needs some cleanup but just sharing in case someone needs it:

<pre><code>public ActionResult FilePage(string completeAlias)
{
 var kntcoFile = FileProvider.GetFile(completeAlias, "en-US", "MySite").FirstOrDefault();
 if (kntcoFile != null)
 {
 DocumentAttachment attachment = kntcoFile.AllAttachments.FirstOrDefault();
 if (attachment != null)
 {
 string kenticoSite = System.Configuration.ConfigurationManager.AppSettings["KenticoSite"];
 string fileUrl = string.Format("{0}getattachment/{1}/{2}", kenticoSite, attachment.AttachmentGUID, kntcoFile.DocumentName);
 byte[] fileBytes = null;

 using (WebClient wc = new WebClient())
 {
 fileBytes = wc.DownloadData(fileUrl);
 }
 return new FileContentResult(fileBytes, attachment.AttachmentMimeType);
 }
 }
 return new HttpNotFoundResult();
}
</code></pre>

entityMap|blocks|key|57f4h|text|我为图像做了类似的事情，所以我修改了我的，希望能在你的场景中工作。需要注意的是，除非调用重载并传入true以返回AttachmentBinary，否则不会返回它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|24c8q|public+ActionResult+FilePage(string+completeAlias)

I did something like this for images, so I modified mine to hopefully work in your scenario. The thing to note is that the AttachmentBinary isn't returned unless you call the overload and pass in true to return it.

<pre><code>public ActionResult FilePage(string completeAlias)
{
 var kntcoFile = FileProvider.GetFile(completeAlias, "en-US", "MySite").FirstOrDefault();
 if (kntcoFile != null)
 {
 DocumentAttachment attachment = kntcoFile.AllAttachments.FirstOrDefault();
 if (attachment != null)
 {
 var attachmentBinary = AttachmentInfoProvider.GetAttachmentInfo(attachment.AttachmentID, true);
 return base.File(attachmentBinary.AttachmentBinary, attachment.AttachmentMimeType);
 }
 }


 EventLogProvider.LogInformation("GetFile", "NOTFOUND", "attachment Not Found" + completeAlias + " /");
 return null;
}
</code></pre>

We're using ASP.NET MVC website with Kentico 11. When a file is uploaded into the CMS using CMS.File page type, we need to retrieve it on MVC side.

I can do the following maybe?

<code>var kntcoFile = FileProvider.GetFile(completeAlias, "en-US", "MySite").FirstOrDefault();</code>

Assuming the API found the file, how to I get access to the binary data of the file so that I can return it to the browser?
