How to select the parent node of a child node in a treeview

Question

I currently have a treeview that gets populated with all the files and directories in the root directory. I need to select the parent directory of a child node programatically.
I have tried some code, but it only allows me to select the root directory, which is the first directory in the treeview and not the parent directory of the child node.
If someone could please help me, I would really appreciate it.
Thanks.

What I have tried:

C#

list.SelectedNode = nodes[0];

You didn't even bother reading the documentation on TreeNode, did you?

Every TreeNode object has a Parent that, obviously, refers to its parent TreeNode.

var parent = someChildNode.Parent;
