{

    public partial class Form1 : Form

        {

            InitializeComponent();

        }

        private void Form1_Load(object sender, EventArgs e)

        {

            System.Xml.XmlDocument document =

            new System.Xml.XmlDataDocument();

            document.Load(@"C:\test\C#\TreeView\TreeView\TreeView\contacts.xml");

            populateTreeControl(document.DocumentElement,

            this.tvPerson.Nodes);

        }

        private void populateTreeControl(

       System.Xml.XmlNode document,

       System.Windows.Forms.TreeNodeCollection nodes)

        {

            foreach (System.Xml.XmlNode node in

            document.ChildNodes)

            {

                // If the element has a value, display it;

                // otherwise display the first attribute

                // (if there is one) or the element name

                // (if there isn't)

                string text = (node.Value != null ? node.Value :

                (node.Attributes != null &&

                node.Attributes.Count > 0) ?

                node.Attributes[0].Value : node.Name);

                TreeNode new_child = new TreeNode(text);

                nodes.Add(new_child);

                populateTreeControl(node, new_child.Nodes);

            }

        }

    }
