[SOLVED: use Examine] The end goal is that if, in Media, I had a folder schema like "`~/Blog/Blog-1/`", I can find the

Id

of

/Blog-1/

so that I can then put images there through MediaService. My current approach is some sort of loop where I start at GetRootMedia, then find the "Blog" folder by name, then find the child folder by getting the ancestors of that folder, like this:

var nameOfRootFolder = "Blog";
var nameOfChildFolder = "Blog-1";
var folder = MediaService.GetRootMedia().FirstOrDefault(x => x.Name.Equals(nameOfRootFolder));
var childrenFolder =
    MediaService.GetAncestors(folder).FirstOrDefault(x => x.Name.Equals(nameOfChildFolder));

...but that feels bad and, irrespective of any performance issues, wouldn't work past one child folder. So like, what should I do? Is this also an examine query off? And if it is an examine query, could someone give me an example of how I'd find a folder by path? Yours truly, Someone who found out that MediaService existed about 3 hours ago.

yep examine might be you friend.. a query on the media content for

nodeName

=

Blog-1

and

__NodeTypeAlias

of

Folder

.. will get you the id, or guid

__Key

of the media folder

OK. I'd like to think I'm better at using Umbraco than I was the last time Examine showed up, so I'll give it another shot. Thank you!

Yup, re-reading through it right now

you can get rid of of some magic strings..

Umbraco.Cms.Core.Constants.UmbracoIndexes.ExternalIndexName

Umbraco.Cms.Infrastructure.Examine.IndexTypes.Media

{ModelsBuilderNamespace}.Folder.ModelTypeAlias

OK brilliant, that's worked magnificently (I'm now calling the query through a controller and have found that's much easier to set-up for testing, as opposed to the route hijacking approach imo). I think I might have to do a separate query to define the correct parent node, but the more I play around with Examine the more obvious that should be. Simple example following the tutorial just to test, and yes this is just getting the Ids for now.

IEnumerable<string> ids = Array.Empty<string>();
if (_examineManager.TryGetIndex("ExternalIndex", out var index))
{
    ids = index.Searcher.CreateQuery("media")
        .NodeTypeAlias("folder")
        .And()
        .Field("nodeName", "Blog-1")
        .Execute()
        .Select(x => x.Id);
}
