I have nodes that can be categorized via a multinode treepicker. When on a page that has selected categories, I want to display three items of "related content" randomly.
So for example if a Meal page has selected "Lunch" and "Snacks" as categories I want the random display to choose a list of three other meals that ALSO have selected "Lunch" OR "Snacks".
The best way I can think of doing this is to make a list of the multinode treepicker items:
and then pull one random node ID from that list, which will then be matched against the full list of All Food and displayed, again, randomly. However, I can't figure out how to randomly pull a node ID from the list.
I'd be grateful if anyone could tell me the best way of going about this.
I think you could generate a random number using the count from your list. Then, use that generated number as an index to obtain the random item in the list.
Random random = new Random();
int index = random.Next(catList.Count);
IPublishedContent randomMealPage = catList[index];
I would have liked to have tried it locally in a setup, but I haven't had the opportunity. Please let me know if it works out for you.

Looks like it works! Thank you!
