How to get the GUID of a node

08/14/2023, 2:48 PMIn a class using IUmbracoContextFactory, I'm trying to get the Guid of a node for later use, but all I get is a load of 00000's. I've tried many things but none work.
I think this should work but it doesn't:
Copy code
var orderConfirmedGuid = siteRoot.DescendantsOrSelf<GeneralPage>().Where(x => x.Name == "Order Confirmed").FirstOrDefault().GetUdi().AsGuid();a

.FirstOrDefault()Anders Bjerner
08/14/2023, 4:23 PMI know this wasn't part of your question, but also some additional tips:
- calls to any Descendant(s) method can be pretty bad for performance for big sites. Might be worth looking for a better way to archive what you're trying to do - although not always there is one
- a call to
.WhereFirstOrDefault.FirstOrDefault(x => x.Name == "Order Confirmed")Guid? orderConfirmedGuid = siteRoot.DescendantsOrSelf<GeneralPage>().FirstOrDefault(x => x.Name == "Order Confirmed")?.Key;j

Where()FirstOrDefault()a

Copy code
OrderConfirmedGuid = siteRoot.DescendantsOrSelf<GeneralPage>().Where(x => x.Name == "Order Confirmed").FirstOrDefault().Key.AsGuid(); Copy code
OrderConfirmedGuid = siteRoot.DescendantsOrSelf<GeneralPage>().FirstOrDefault(x => x.Name == "Order Confirmed").Key.AsGuid();d
