It's basically the same way you would handle content. So once you have a reference to the folder, you can call Children() to get it's immediate children or Descendants() to get all items in the folder, however nested (this might bring back other folders, too).
eg.
var folder = Umbraco.TypedMedia(1234);
var allMedia = folder.Descendants();
Or to get all descendant media that is NOT a folder you can do:
var media = folder.Descendants().Where(f => f.DocumentTypeAlias != global::Umbraco.Core.Constants.Conventions.MediaTypes.Folder);
Because I'm using it on a SurfaceController, I'm 100% positive that there's media images inside the folder, and the foreach is broken immediately, altough .Descendants() are not null.
Here's my usage:
var folderId = 1234;
var folder = Umbraco.TypedMedia(folderId);
var allMedia = folder.Descendants();
foreach(var media in allMedia)
{
listOfAllUrls.Add(media.Url);
}
Actualy, 'allMedia.Current' is null but not 'allMedia'
You can use the logic in a controller or a view - the principle is the same.
You probably need to do a null check to ensure that folder exists, and maybe also check if it's a folder type? Are you sure the Id is correct? Check for the ID in the Umbraco Media tree.
if (folder != null)
{
var allMedia = folder.Descendants();
foreach (var media in allMedia)
{
//...
}
}
But that code will definitely work. Presumably you have a List<string> called listOfAllUrls that you are adding this media to? (Though it would be simpler just to use folder.Descendants().Select(x => x.Url).ToList() to do that.
Also, make sure you have included the using Umbraco.Web namespace.
Iterate trough all images in a Media folder
Hi all.
How can I iterate trough all images/objects existing inside one predefined media folder?

Note: Same result with the 2nd approach.
