and of course :
Clear(); is correct .
I believe you need to get an instance of the "Root" TreeNode, then Clear its Nodes property.

Aside from the fact that this question is already solved, your solution is incorrect:

* If there are five or more child nodes, your code will remove nodes 0, 2, and 5, leaving 1, 3, and 6+ unscathed.

* If there are less than five child nodes, your code will throw an exception.
