Hi Pravesh,

You can use this code:
using System;
using System.Data;
using System.Windows.Forms;
using System.Xml;
using System.IO;
 
namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
            XmlDataDocument xmldoc = new XmlDataDocument();
            XmlNode xmlnode;
            FileStream fs = new FileStream("tree.xml", FileMode.Open, FileAccess.Read);
            xmldoc.Load(fs);
            xmlnode = xmldoc.ChildNodes[1];
            treeView1.Nodes.Clear();
            treeView1.Nodes.Add(new TreeNode(xmldoc.DocumentElement.Name));
            TreeNode tNode;
            tNode = treeView1.Nodes[0];
            AddNode(xmlnode, tNode);
        }
 
        private void AddNode(XmlNode inXmlNode, TreeNode inTreeNode)
        {
            XmlNode xNode;
            TreeNode tNode;
            XmlNodeList nodeList;
            int i = 0;
            if (inXmlNode.HasChildNodes)
            {
                nodeList = inXmlNode.ChildNodes;
                for (i = 0; i <= nodeList.Count - 1; i++)
                {
                    xNode = inXmlNode.ChildNodes[i];
                    inTreeNode.Nodes.Add(new TreeNode(xNode.Name));
                    tNode = inTreeNode.Nodes[i];
                    AddNode(xNode, tNode);
                }
            }
            else
            {
                inTreeNode.Text = inXmlNode.InnerText.ToString();
            }
        }
    }
}
