Accessing all the nodes in TreeView Control

Question

I have a TreeView Control with set of nodes and child nodes. For example:

ROOT has A,B,C.

A has a1, a2, a3 and then

Answer 1

Don't use nested loops, but go for an recursive solution like:

void ListNodes( TreeNode node )
{
  foreach( var subnode in node.Nodes )
  {
    ListNodes( subnode );
  }
  // Print out node
}

Call this function for your root node.

For your additional question: check the FullPath property.
