I'm having trouble getting the .Where clause to work with DynamicMedia.
I want to get the descendants of a certain media folder, and then filter out all the folders.
I can explicitly code this but i came across the .Where option and figured it would be a much more elegant way to do this.
Unfortunately, it just isn't happening...
var images = new DynamicMedia(rootNode).Descendants().Where("NodeTypeAlias == \"Image\"");
Any ideas?
Thanks in advance.S.
You're close, but you aren't using DynamicMedia dynamically. Use Library.MediaById() which returns the dynamic version of the DynamicMedia object.
var images = Library.MediaById(-1).Descendants().Where("NodeTypeAlias == @0", "Image");
Also, the Descendants() method takes a the NodeTypeAlias as a parameter, so the above snippet can be shortened to:
var images = Library.MediaById(-1).Descendants("Image");
Check out the Razor DynamicNode Cheatsheet for a list of all the available properties and methods. It may also be helpful to run through the Umbraco 4.7 Razor Feature Walkthrough.
Ok, that's still not working.
Firstly, I am using this in a .ashx file so I haven't been able to find which using statement is needed to access Library.
Looking on the web I read to substitue RazorLibraryCore(null).MediaById for Library.MediaById.
That seemed to compile ok but then I get an error of "Can only unbox from an object or interface type to a value type".
