Get a list of all tree nodes (in all levels) in TreeView Controls

Question

How can I get a list of all tree nodes (in all levels) in a TreeView control?

Answer 1

Because TreeView has many levels, do recursive function:

   public void AddNodeAndChildNodesToList(TreeNode node)
    {
        listBox1.Items.Add(node.Text);    // Adding current nodename to ListBox     

        foreach (TreeNode actualNode in node.Nodes)
        {
            AddNodeAndChildNodesToList(actualNode); // recursive call
        }
    }

Than call this function for all first level Nodes in TreeView:

    foreach (TreeNode actualNode in treeView1.Nodes)         // Begin with Nodes from TreeView
    {
         AddNodeAndChildNodesToList(actualNode);
    }

Code is from site C# TreeView
