How can i add the strings to child nodes inside a node?

Question

I have this code:

TreeNode newNodeText = null;
TreeNode newNodeParsed = null;
TreeNode rootNode = treeView1.Nodes[0];

if (!txtDir.Text.Contains("/"))
{
    newNodeText = new TreeNode(txtDir.Text);
    rootNode.Nodes.Add(newNodeText);
}
else
{
    List<string> test1 = txtDir.Text.Split('/').ToList();
    for (int i = 0; i < test1.Count; i++)
    {
        newNodeParsed = new TreeNode(test1[i]);
        rootNode.Nodes.Add(newNodeParsed);
    }                       
}

If in the textBox(txtDir) the string i type dosen't contain any '/'then the new node will be add under the root in the treeView1.

But if i type in the textBox(txtDir) for example test1/test2/test3/test4 Then i need that test1 will be under root under the rootNode but test2 will be inside test1 and test3 to be inside test2 and test4 inside test3

Inside i mean under like a sub directory.

I need do it in the else part for now it will just add it to the root.

You can't keep adding the nodes to the same parent, so try updating the reference to the new parent as you loop:

TreeNode nextNode = rootNode;
for (int i = 0; i < test1.Count; i++) {
  newNodeParsed = new TreeNode(test1[i]);
  nextNode.Nodes.Add(newNodeParsed);
  nextNode = newNodeParsed;
}
