How to recursively populate a TreeView with JSON data

The problem is that, as you recursively descend the JToken hierarchy, you also need to recursively descend the TreeNode hierarchy you are creating, adding child nodes to the parent node just created, rather than the root node, along the lines of Recursion, parsing xml file with attributes into treeview c#.

Thus if you do:

    private void Form1_Load(object sender, EventArgs e)
    {
        using (var reader = new StreamReader(path))
        using (var jsonReader = new JsonTextReader(reader))
        {
            var root = JToken.Load(jsonReader);
            DisplayTreeView(root, Path.GetFileNameWithoutExtension(path));
        }
    }

    private void DisplayTreeView(JToken root, string rootName)
    {
        treeView1.BeginUpdate();
        try
        {
            treeView1.Nodes.Clear();
            var tNode = treeView1.Nodes[treeView1.Nodes.Add(new TreeNode(rootName))];
            tNode.Tag = root;

            AddNode(root, tNode);

            treeView1.ExpandAll();
        }
        finally
        {
            treeView1.EndUpdate();
        }
    }

    private void AddNode(JToken token, TreeNode inTreeNode)
    {
        if (token == null)
            return;
        if (token is JValue)
        {
            var childNode = inTreeNode.Nodes[inTreeNode.Nodes.Add(new TreeNode(token.ToString()))];
            childNode.Tag = token;
        }
        else if (token is JObject)
        {
            var obj = (JObject)token;
            foreach (var property in obj.Properties())
            {
                var childNode = inTreeNode.Nodes[inTreeNode.Nodes.Add(new TreeNode(property.Name))];
                childNode.Tag = property;
                AddNode(property.Value, childNode);
            }
        }
        else if (token is JArray)
        {
            var array = (JArray)token;
            for (int i = 0; i < array.Count; i++)
            {
                var childNode = inTreeNode.Nodes[inTreeNode.Nodes.Add(new TreeNode(i.ToString()))];
                childNode.Tag = array[i];
                AddNode(array[i], childNode);
            }
        }
        else
        {
            Debug.WriteLine(string.Format("{0} not implemented", token.Type)); // JConstructor, JRaw
        }
    }

You will get the following tree view structure:
