Oh, not again!
Tag it! WPF, WinForms, ASP.NET, what?!!

Assuming you want to work with System.Windows.Forms.TreeView, use System.Windows.Forms.TreeView.Nodes property; it has the methods you need.

That's the way I'd answered if my caffeine level wasn't that low ;)

Thank you. Caffeine is not needed for work. It does not hurt much though, in my opinion. I'm more under tannin, but not concerned about it.

Why selected? Basically, correct, but you need to indicate, for what library? (And OP should tag it!)
Please see my Answer.

Michel [mjbohn] 11-Apr-11 3:02am

But OP has tagged C#. And because the question wasn't that detailed I showed both selected and index
[EDIT] You surely meant ASP,WPF etc to be tagged. Need more caffeine to awaken :)

No, C# is not enough. For example, in WPF the answer would be different.

I've written what I meant. See also my comment to the Question, it is correct.

Google is your friend: Be nice and visit him often. He can answer questions a lot more quickly than posting them here...

If you had searched using your subject, you would have found the answer on MSDN[^]

The OP who do not indicate which UI library is used usually cannot use Google.
They do the search and see 3-4 or more different Tree Views. Which one to look at? :-)
Nevertheless, you're right. My 5.
