If yes how is it done in VS C#?

If you can't read my code, try converting it here[^]

Not only is there nothing close but nothing near the planet

1. Nodes.Find[^]
   
2. Looping all nodes yourself (recursively!) and checking it (will be harder if the tree lazyloads, and should ideally be done on the datasource, not the tree itself)
